1 00:00:01,350 --> 00:00:10,920 This is Derek Hockaday talking with much investor at his home in Fallbrook on the 4th of June to one for Martin. 2 00:00:10,920 --> 00:00:15,360 Just tell me how you came to come to Oxford. What led to that? 3 00:00:15,360 --> 00:00:26,070 Well, the immediate reason was that Richard Doll later Sir Richard Doll was appointed Regis, professor of Medicine. 4 00:00:26,070 --> 00:00:35,580 Prior to that, he had going to be deputy director of the MRC Clinical Research Centre at North Park. 5 00:00:35,580 --> 00:00:46,320 And I was all set really for a shift to North Park, but then somewhat out of the blue became the Regis professor appointment. 6 00:00:46,320 --> 00:00:49,710 And in those days, it was still a little bit of money around. 7 00:00:49,710 --> 00:00:58,080 And Richard was able to bring three or four of his sort of chosen junior colleagues with him. 8 00:00:58,080 --> 00:01:06,300 These included Malcolm Pike, Richard Peto, the Peter Smith and myself and one or two others. 9 00:01:06,300 --> 00:01:11,340 And so we were able to come to posts at Oxford. 10 00:01:11,340 --> 00:01:15,810 So in July 1969, I think it was. 11 00:01:15,810 --> 00:01:24,800 I became a clinical lecturer in Richard Dols department, the department at the Regis Professor of Medicine. 12 00:01:24,800 --> 00:01:36,900 And now that was. Were you in the main building up in the George Pickering's Road area, or were you in over towards the institute? 13 00:01:36,900 --> 00:01:44,160 We were in the George Pickering area and a very prominent person there, 14 00:01:44,160 --> 00:01:52,080 and somebody who I remember very fondly was John Oliver, who is who was first assistant. 15 00:01:52,080 --> 00:01:58,470 And I found John very supportive and helpful person. 16 00:01:58,470 --> 00:02:07,620 Some people found him a little difficult at times. I always found John extremely helpful and I was very pleased to have him around. 17 00:02:07,620 --> 00:02:13,920 Obviously, there were others left over from George Pickering's time. 18 00:02:13,920 --> 00:02:20,700 Perhaps the most notable would be Laurie Bailin, who was who's now a professor in Australia, where he'd be retired now. 19 00:02:20,700 --> 00:02:31,920 But at that time he was, I think he was one of the first assistant to the Regis professor and a very good clinician, another very nice person. 20 00:02:31,920 --> 00:02:36,240 And there were lots of other, very pleasant people there, too. 21 00:02:36,240 --> 00:02:43,620 I'm interested what you said about Joan, because your sort of medicine was in German sort of medicine and he was a laboratory worker. 22 00:02:43,620 --> 00:02:48,030 It's very good that he was able to facilitate your sort of supplies. 23 00:02:48,030 --> 00:02:54,390 Well, I can give you one reason why I was in favour from word go. 24 00:02:54,390 --> 00:03:06,120 And that's simply we both were derived from University College Hospital and John Lewis said, absolutely. 25 00:03:06,120 --> 00:03:12,450 So John Arnold was very, very loyal to you C-H, and there were quite a lot of people around. 26 00:03:12,450 --> 00:03:19,680 But if you were from UC H, then that certainly gave you a good start in the John and rigidly had been there. 27 00:03:19,680 --> 00:03:27,240 No. Well, Richard Richard, certainly the MRC Statistical Research Unit, 28 00:03:27,240 --> 00:03:37,290 which is the outfit I joined when I joined Richard Doll in 1966 that was based at University College Hospital Medical School, 29 00:03:37,290 --> 00:03:45,930 but Richard himself was not a graduate of fussy age. I can't remember exactly which medical school he came from, but it wasn't UK age. 30 00:03:45,930 --> 00:03:53,490 What led you to go towards epidemiology and statistics and research in that sort of field? 31 00:03:53,490 --> 00:04:01,470 Yes. Well, that that is actually an interesting question. 32 00:04:01,470 --> 00:04:03,750 When I was at school, 33 00:04:03,750 --> 00:04:14,790 I had always assumed design is going to become an engineer because I've always been deeply interested in mechanical devices and engineering devices. 34 00:04:14,790 --> 00:04:23,640 And when I went into the lower sixth form at my school, I went into the maths, physics and chemistry six four. 35 00:04:23,640 --> 00:04:29,460 But my headmaster intervened and said that was not what he hoped I would do. 36 00:04:29,460 --> 00:04:39,810 And at that stage, after a lot of bargaining, he persuaded me to go into the biological sixth form and do botany, zoology, chemistry and physics. 37 00:04:39,810 --> 00:04:50,820 And that, of course, meant that I then became a doctor because I think of the 12 boys in that class, 11 became doctors. 38 00:04:50,820 --> 00:05:00,030 Even at that time, I was very interested in data on how and why and and quite numerical. 39 00:05:00,030 --> 00:05:10,050 And during my medical training, I was always very interested in aetiology and pathogenesis and how things, 40 00:05:10,050 --> 00:05:15,630 how they occurred in the community for infectious diseases, how they spread and things of that sort. 41 00:05:15,630 --> 00:05:29,550 So that interest was always very latent. Now, after I qualified, I actually made a remarkable and unusual decision. 42 00:05:29,550 --> 00:05:38,010 I decided, in fact, to take time away from clinical medicine and to learn about statistics and computing. 43 00:05:38,010 --> 00:05:43,470 And I was fortunate enough to obtain a post in the Department of Statistics at Rotherham, 44 00:05:43,470 --> 00:05:46,980 said Experimental Station, which is actually an agricultural show. 45 00:05:46,980 --> 00:05:57,030 But that, of course, was headed by Dr Frank Yates, who is the officer in Yates, a highly distinguished statistician. 46 00:05:57,030 --> 00:06:06,870 And I worked there with two people. I work with Dr Brian Leach, who is a veterinary epidemiologist, and we're Dr Michael Healy. 47 00:06:06,870 --> 00:06:12,900 Michael Healy, eventually becoming professor of medical statistics at the London School of Hygiene and Tropical Medicine. 48 00:06:12,900 --> 00:06:20,730 And I also became very closely involved with an obstetrician gynaecologist, Leonard Baron from Newcastle, 49 00:06:20,730 --> 00:06:24,810 and we started analysing data and writing papers together while I was there. 50 00:06:24,810 --> 00:06:30,510 He was up in New York. He was up in Newcastle. Tragically or sadly, he was late 80s. 51 00:06:30,510 --> 00:06:36,570 He died last December, a very valued friend and colleague. 52 00:06:36,570 --> 00:06:44,730 After a while, I decided that I had probably learnt enough about statistics and computing as much as I wanted to learn anyway, 53 00:06:44,730 --> 00:06:49,140 and I decided to go back to clinical medicine, which I did for a while. 54 00:06:49,140 --> 00:06:54,450 So I actually completed my house appointments very late. 55 00:06:54,450 --> 00:07:01,410 Both of them were done at Barnet General Hospital and the first one was done with. 56 00:07:01,410 --> 00:07:04,770 The surgical job was done with David Bailey, 57 00:07:04,770 --> 00:07:12,030 who had been first met at first surgical assistant at U.S. age and who I knew well, who was very good to me. 58 00:07:12,030 --> 00:07:21,420 And the second was with Dr. Oliver Garrard Garrard, who was a distinguished physician, and I learnt a lot there at the end of the year. 59 00:07:21,420 --> 00:07:30,360 I was uncertain whether to continue with clinical medicine or whether to move into epidemiology. 60 00:07:30,360 --> 00:07:38,400 It was really meeting Richard Doll and talking to Richard Doll that persuaded me that I would actually like to become an epidemiologist. 61 00:07:38,400 --> 00:07:43,230 And that's how it answered. Yeah, I met Richard at Rotherham St. 62 00:07:43,230 --> 00:07:49,470 Richard quite often came to Rotherham, said he was doing quite a lot of work with Michael Healey, right? 63 00:07:49,470 --> 00:07:56,490 And so that's really how I first met Richard, and that's where we met and those around, you know, 64 00:07:56,490 --> 00:08:06,270 and I met while we were still at school and we first met when I was 17 and she was 15. 65 00:08:06,270 --> 00:08:19,050 And it she was really, quite frankly, so beautiful that I tell you it was the first time I saw her. 66 00:08:19,050 --> 00:08:24,370 And it produced a relationship, a happy relationship. 67 00:08:24,370 --> 00:08:30,060 But she was the last it. We've now we're now well beyond our diamond wedding. 68 00:08:30,060 --> 00:08:34,380 So there is some reason I always connected with references to that room. 69 00:08:34,380 --> 00:08:36,870 And you are. No, you are absolutely right. 70 00:08:36,870 --> 00:08:48,450 Because Anne, she worked as a secretary at UCL and she worked for Jay-Z Young and she worked for Linda Brown, George and she. 71 00:08:48,450 --> 00:08:53,730 She then went and worked. Rossum stayed in Frank Gates's departments. 72 00:08:53,730 --> 00:08:58,710 Have I when she went there because you were there, you know, she was there. 73 00:08:58,710 --> 00:09:08,910 That's the thing to do in there. No, I don't. I don't think it's I and was working at Rotherham instead before I went there. 74 00:09:08,910 --> 00:09:15,790 And she continued to work there for quite a while afterwards. 75 00:09:15,790 --> 00:09:19,800 That's something that I was wondering about when you joined Richard Doll. 76 00:09:19,800 --> 00:09:27,780 Were you at that stage doing your own number crunching or were you already relying upon big computers? 77 00:09:27,780 --> 00:09:35,880 No, by then, by the time I joined Richard, so most of the stuff we did was being done on computers. 78 00:09:35,880 --> 00:09:48,810 But on the other hand, the desk calculator was also the vital bits of equipment we had the highly obnoxious bronze figure machines, 79 00:09:48,810 --> 00:09:59,810 which which are dreadful to use, and we also had really quite nice machines made by facet desk calculators and also, I think, electronic calculators. 80 00:09:59,810 --> 00:10:12,440 Just about beginning to appear. But no, we used the University of London computing facilities and I I was competent enough to do what I needed to do. 81 00:10:12,440 --> 00:10:21,740 The University of London computers. So when you moved to Oxford, how did the facilities for computing compare with London's? 82 00:10:21,740 --> 00:10:29,810 Well, I think the facilities for computers at Oxford probably were better, right? 83 00:10:29,810 --> 00:10:47,060 Although I had less to do with them immediately than I did while I was in London, because most of the work I did at Oxford was collaborative. 84 00:10:47,060 --> 00:10:59,960 And usually the even in those early days would involve somebody who was more experts at computers and computing than I was. 85 00:10:59,960 --> 00:11:08,030 I mean, fortunately, I had learnt enough to understand how things worked and what programmes did what and what results meant and things. 86 00:11:08,030 --> 00:11:09,050 Things of that sort. 87 00:11:09,050 --> 00:11:19,080 But nonetheless, I wasn't really after I can do what's really in the frontline of computing, and that would be the boundaries set up, 88 00:11:19,080 --> 00:11:26,120 which is that if this was indeed then based in Bambi Road and the computer that was in use when I arrived there, 89 00:11:26,120 --> 00:11:37,340 this computer and which seemed to do what was required, but of course, compared with what we have now was laughable. 90 00:11:37,340 --> 00:11:44,210 I remember Jim, then men were dinky. So was there a sort of little subsection there? 91 00:11:44,210 --> 00:11:52,040 Well, what happened was I came I came with Richard in 1969, 92 00:11:52,040 --> 00:12:05,120 and the one of the first things I said about doing in my spare time to the distress of my family was to write my MDA thesis. 93 00:12:05,120 --> 00:12:14,030 And this was on the basically all the benefits and risks of oral contraceptives and air in which I have done a lot of work 94 00:12:14,030 --> 00:12:22,730 and I'd done a lot of work on that topic while still at the statistical unit in the Multi Statistical Research Unit. 95 00:12:22,730 --> 00:12:29,780 So that occupied my spare time. During the day, I was doing all sorts of other things. 96 00:12:29,780 --> 00:12:36,140 Other projects of various sorts, some of were MRC projects and some of them the other sorts of projects. 97 00:12:36,140 --> 00:12:43,400 And I I stayed as a lecturer in Richard's department until 1972, 98 00:12:43,400 --> 00:12:53,750 when I then went to the United States for six months and worked with a man called Herschel Drake on drug safety studies. 99 00:12:53,750 --> 00:12:58,550 He ran an outfit called the Boston Globe Drug Surveillance Programme. 100 00:12:58,550 --> 00:13:03,680 So I worked with him in 1972. That wasn't a sabbatical. 101 00:13:03,680 --> 00:13:10,490 It was unpaid leave. But I may say I was paid twice as much in America as I was in Britain. 102 00:13:10,490 --> 00:13:19,730 When I came back for a short while, I was acting director of the DHS, 103 00:13:19,730 --> 00:13:26,210 as it was then the DHS as a cancer unit, a unit which had been directed by Richard Doll. 104 00:13:26,210 --> 00:13:38,510 But he was sort of reaching retirement age. And but I was it was while I was doing that job that I was asked if I would become 105 00:13:38,510 --> 00:13:46,100 would accept the post of this sort of social media dimension that was in late 72. 106 00:13:46,100 --> 00:13:53,060 I was asked, no, sorry in 1973. Mm-Hmm. And I did agree to that. 107 00:13:53,060 --> 00:13:59,180 So I became head of that group, and that group was based in Kimball Road. 108 00:13:59,180 --> 00:14:07,180 It was I took over the premises that had been occupied by my priest, predecessor Alice Stewart. 109 00:14:07,180 --> 00:14:16,160 And it was one of the people, roadhouses, and that's where Jim and others were based. 110 00:14:16,160 --> 00:14:20,240 So that's why Jim was there and indeed why I was there. 111 00:14:20,240 --> 00:14:25,070 When you were working with Richard Perle before you came to Oxford. 112 00:14:25,070 --> 00:14:29,870 First few years in Oxford. Was he somebody who very much directed the group? 113 00:14:29,870 --> 00:14:39,500 Or did each member more or less do what interests me and the bit of each, really? 114 00:14:39,500 --> 00:14:54,050 Richard was certainly always interested in what members of his outfit were doing, and he was always available for advice and encouragement, 115 00:14:54,050 --> 00:15:00,410 and he would read through draughts of papers very carefully and often was a co-author. 116 00:15:00,410 --> 00:15:05,180 But he for the most part, 117 00:15:05,180 --> 00:15:11,660 he did let people pursue subjects that interested them precisely provided that they 118 00:15:11,660 --> 00:15:17,850 were relevant to their image and important and that they were going to be done well. 119 00:15:17,850 --> 00:15:26,600 Now, in fact, it's worth mentioning here that one of the first tasks I was given when I joined 120 00:15:26,600 --> 00:15:33,200 the MRC Statistical Research Unit in 1966 at UCLA under Richard's direction. 121 00:15:33,200 --> 00:15:43,760 One of the very first things I was asked to do was to investigate the possible relationship between venous thromboembolism and oral contraceptive use. 122 00:15:43,760 --> 00:15:53,690 And I set up one of the definitive studies which showed that there was a very marked increase in risk of venous thromboembolism. 123 00:15:53,690 --> 00:15:58,370 The relative risk was about eight for the oral contraceptives that didn't use. 124 00:15:58,370 --> 00:16:03,960 It was a hospital based case control study. So that was something that Richard asked me to do. 125 00:16:03,960 --> 00:16:11,330 One on behalf of the MRC one hospital group 19 hospitals was included in that study. 126 00:16:11,330 --> 00:16:23,810 And it gave such clear results that it gave me an enormous insight into the methodology of studies established to examine the safety, 127 00:16:23,810 --> 00:16:31,280 in particular a widely used medications. And it launched my career in two directions. 128 00:16:31,280 --> 00:16:43,520 First of all, in the direction of drugs and drug safety, and during my working life, I worked very, very extensively with the CSM and the MHRA. 129 00:16:43,520 --> 00:16:54,650 And secondly, on the field of fertility and control of fertility with which in which I work very extensively with the World Health Organisation. 130 00:16:54,650 --> 00:17:03,470 So a lot of my work went sort of in the woman's health is and the other branch really went more broadly into the drug safety in direction. 131 00:17:03,470 --> 00:17:10,910 MHRA Did you say what the Medicines and Healthcare Products Regulatory Agency, what used to be this? 132 00:17:10,910 --> 00:17:18,020 Well, the CSM, I think, is the Commission on Human Medicines and the Dunlop Committee is and started off. 133 00:17:18,020 --> 00:17:24,890 You remember, following thalidomide, all those horrors I put in about 30 years or one or other of their bodies. 134 00:17:24,890 --> 00:17:34,910 And in fact, I only stopped. Yeah. In fact, I did some work last year at the age of 77, so but I don't think I likely do anymore. 135 00:17:34,910 --> 00:17:40,440 And did that mean a lot of travelling up to London? Yes. One day a week or. 136 00:17:40,440 --> 00:17:46,040 Oh well, I did a lot of travelling up to London anyway, as I did lots of other things. 137 00:17:46,040 --> 00:17:55,670 But the CSA meetings were monthly, but at one time I was also doing the. 138 00:17:55,670 --> 00:18:04,880 There was a separate adverse reactions drug and the drug committee that was considered an adverse 139 00:18:04,880 --> 00:18:11,510 drug reactions and that used to meet also monthly and they wouldn't be at the same time. 140 00:18:11,510 --> 00:18:17,990 So even even in that area, I could be trundling up to London for two days a month. 141 00:18:17,990 --> 00:18:27,260 But as I said they were, I was still heavily involved with the MRC and various other bodies, so I did plenty of commuting to London. 142 00:18:27,260 --> 00:18:33,440 And how much reviewing, you know, looking at projects. And so for the MLC, would you have done a lot? 143 00:18:33,440 --> 00:18:45,200 Yeah, a lot, but not as much as I ended up doing for W.H.O., but I put huge amounts of effort into W.H.O. 144 00:18:45,200 --> 00:18:54,020 I the the the the section that deals with human reproduction. 145 00:18:54,020 --> 00:19:01,250 The control of fertility was certainly during the time I was principally active. 146 00:19:01,250 --> 00:19:06,810 A very important part of W.H.O. I don't know how important it is now. 147 00:19:06,810 --> 00:19:16,760 I hope it's still very important because too many people see same day Graeme Smith was involved with David and David and I. 148 00:19:16,760 --> 00:19:23,330 We had many a chuckle together and you travel up together sometimes. 149 00:19:23,330 --> 00:19:32,300 David's wonderful sense of humour used to pop up every, every meeting, really. 150 00:19:32,300 --> 00:19:38,660 He used to. He used to laugh at me a lot because I always insisted on eating polio medicine, 151 00:19:38,660 --> 00:19:43,310 sometimes chocolate during the meetings, and he he he was tickled pink by that. 152 00:19:43,310 --> 00:19:48,700 I didn't quite know quite why he found it so funny, but it was quite funny. 153 00:19:48,700 --> 00:19:55,880 Now, while you were involved with contraceptives, did you get into the world of fertilisation? 154 00:19:55,880 --> 00:20:00,230 And I mean, stepped in it with the role that only. 155 00:20:00,230 --> 00:20:16,610 Only indirectly, insofar as that area of activity was a major interest to W.H.O. because W.H.O. was not only concerned with control of fertility, 156 00:20:16,610 --> 00:20:28,850 but also with infertility, which is a tragic problem just as unwanted children can be a tragic problem. 157 00:20:28,850 --> 00:20:40,130 So the I certainly served on all this with Steptoe at W.H.O., but I never did any research in those areas. 158 00:20:40,130 --> 00:20:49,490 And now, you know, to the outsider, the contraceptives seem to veer to and fro a bit as to their dangers. 159 00:20:49,490 --> 00:20:53,210 And would you agree with that or? 160 00:20:53,210 --> 00:21:09,940 Well, I think one of the major problems right the way through was with the media and the 10 still to the 10 still to be true. 161 00:21:09,940 --> 00:21:18,710 I, they often report inaccurate information and sometimes information that is completely wrong. 162 00:21:18,710 --> 00:21:28,610 And because contraception at that time at least was the sort of subject that always caused people to pick up their ideas. 163 00:21:28,610 --> 00:21:39,770 Any finding that you came out with or others came out with would excite a lot of attention in the media, especially if it was bad news. 164 00:21:39,770 --> 00:21:44,130 And I may say an awful lot of the work I did resulted in good news. 165 00:21:44,130 --> 00:21:53,150 Yes. For instance, we were very much involved in demonstrating that oral contraceptive use has no important effect on breast cancer. 166 00:21:53,150 --> 00:21:56,560 It does in current use by young people. 167 00:21:56,560 --> 00:22:05,080 It increases risk by a tiny amount because the disease is so rare in users who are young. 168 00:22:05,080 --> 00:22:10,880 The effect is really barely detectable even in huge studies. 169 00:22:10,880 --> 00:22:25,070 And of course, the balance of benefit and risk for oral contraceptives is definitely now been shown in many studies, including those of our own. 170 00:22:25,070 --> 00:22:32,060 To be positive, the benefits outweigh the risks. That doesn't mean there are no risk, but the benefits outweigh the risks. 171 00:22:32,060 --> 00:22:37,970 The the other thing I would say is that although I was very interested in contraception, 172 00:22:37,970 --> 00:22:44,150 not just oral contraceptives, but other approaches, including sterilisation and also an abortion, 173 00:22:44,150 --> 00:22:55,370 but I became more generally interested in women's health, and I became increasingly interested in the old reproductive cancers and in breast cancer. 174 00:22:55,370 --> 00:23:01,790 I became interested in the menopause and its consequences, perhaps especially osteoporosis, 175 00:23:01,790 --> 00:23:06,740 but also called it kind of the cardiovascular consequences. 176 00:23:06,740 --> 00:23:16,160 And also in the 1980s onwards, I became heavily involved in these screening issues in relations, 177 00:23:16,160 --> 00:23:23,390 especially the breast and service that turned out to be an interesting area. 178 00:23:23,390 --> 00:23:27,650 Were you involved in the herpes and cervical cancer story? 179 00:23:27,650 --> 00:23:35,570 Not here again. Not not directly in that. 180 00:23:35,570 --> 00:23:42,980 I mean, we didn't collect samples that were then investigated for evidence of herpes infection, 181 00:23:42,980 --> 00:23:54,080 but we did do studies that were very relevant to the infectious aetiology or the basically infectious aetiology of cancer of the cervix. 182 00:23:54,080 --> 00:24:11,480 We did a very risky study in which we investigated the husbands of women who had only ever had one partner, 183 00:24:11,480 --> 00:24:16,820 but women who nonetheless had cancer of the cervix. 184 00:24:16,820 --> 00:24:32,600 And we found that essentially all the women who to the best of our endeavours investigations had only ever had one partner, either husband. 185 00:24:32,600 --> 00:24:38,000 We found that in every case virtually, that was not true for their husband. 186 00:24:38,000 --> 00:24:47,390 And obviously, that supported the notion that there was an infectious agent of his herpes was of interest in the early days. 187 00:24:47,390 --> 00:24:59,260 But of course, is human papillomavirus subtypes really the underlying problem with with cancer, the cervix and and people don't. 188 00:24:59,260 --> 00:25:02,470 Really speaking, don't get. 189 00:25:02,470 --> 00:25:11,790 Certainly the common forms of cervical cancer without human papillomavirus, but other things may accentuate the effect of human papillomavirus. 190 00:25:11,790 --> 00:25:16,800 So how did you find that out by talking to the husbands at length? 191 00:25:16,800 --> 00:25:22,140 I mean, was that sort of evidence is that this is published? 192 00:25:22,140 --> 00:25:26,100 Derek, unfortunately in The Lancet. 193 00:25:26,100 --> 00:25:38,370 But we we interviewed the women as part of a study of the aetiology of cancer, the cervix, and it was done by a careful interview. 194 00:25:38,370 --> 00:25:53,910 And then we let a long time interval pass it, and we then undertook a study of the factors affecting disease and illness in the men themselves. 195 00:25:53,910 --> 00:26:02,940 But we also incorporated the questions that we wanted to ask about sexual partners, 196 00:26:02,940 --> 00:26:13,800 and I'm happy to say that no link was made at the time between the two sets of interviews. 197 00:26:13,800 --> 00:26:19,350 I may say this this study obviously went through. An ethics committee was done in the 1980s. 198 00:26:19,350 --> 00:26:23,690 The interviewing of the men was all done by David Skegg, right? 199 00:26:23,690 --> 00:26:27,930 Hugh Davies, of course, later became vice chancellor. 200 00:26:27,930 --> 00:26:36,180 Until very recently, he's been vice chancellor of the University of Otago in New Zealand, and David had the courage to do these tricky interviews. 201 00:26:36,180 --> 00:26:47,250 But we did leave a long gap. Yes, and there was no obvious linkage between the two interviews, but it was a difficult study. 202 00:26:47,250 --> 00:26:52,560 We thought a lot about doing doing it, and we did get ethical committee permission to do it. 203 00:26:52,560 --> 00:26:59,490 And it is written up in The Lancet. Good to go to the meeting with. 204 00:26:59,490 --> 00:27:04,560 No prescribing is to be straight with the man today or for symptoms. 205 00:27:04,560 --> 00:27:14,840 Has that proven to be bad news or good news? Well, I don't think anybody for a long time would dream of prescribing still being wrong. 206 00:27:14,840 --> 00:27:23,850 The the we got very heavily into the investigation of hormone replacement therapy. 207 00:27:23,850 --> 00:27:35,230 It followed on on very logically from other work we've done and interested in menopause and postmenopausal events. 208 00:27:35,230 --> 00:27:41,940 The initially, as you know, 209 00:27:41,940 --> 00:27:49,860 the message in relation to hormone replacement therapy was feminine forever and 210 00:27:49,860 --> 00:27:59,010 long term use of primary principally conjugated equine oestrogens was encouraged, 211 00:27:59,010 --> 00:28:08,610 especially in the United States. Then it was discovered that unopposed oestrogen has increased the risk of thromboembolism. 212 00:28:08,610 --> 00:28:13,230 This is why I'm sorry I might say increase the risk of of endometrial cancer, 213 00:28:13,230 --> 00:28:20,430 but unopposed stimulation of the end of each year, resulting in endometrial cancer that caused a bit of a hiccup. 214 00:28:20,430 --> 00:28:27,720 And that led to the incorporation of a progestogen component in hormone replacement therapy because 215 00:28:27,720 --> 00:28:36,300 the progesterone would suppress the oestrogenic stimulation of the endometrium that later on, 216 00:28:36,300 --> 00:28:38,670 other problems began to emerge. 217 00:28:38,670 --> 00:28:52,890 We did the study in the mid-nineties, which we we thought would be a safety study looking at hormone replacement therapy and thromboembolism, 218 00:28:52,890 --> 00:29:00,360 and we thought it was a safety study because nobody believed that hormone replacement therapy, as opposed to the bill, caused thromboembolism. 219 00:29:00,360 --> 00:29:06,090 And this study was largely funded by sharing much to their credit. 220 00:29:06,090 --> 00:29:10,860 I may say because as it turned out, when we completed the study, 221 00:29:10,860 --> 00:29:20,460 we found that hormone replacement replacement therapy did have a two to threefold effect on increasing the risk of thromboembolism. 222 00:29:20,460 --> 00:29:32,790 So that was another problem for HRT. In the early days, it was believed that HRT is protective against cardiovascular disease, 223 00:29:32,790 --> 00:29:37,380 and I must admit that some of the early studies did support that point of view, 224 00:29:37,380 --> 00:29:53,370 but they were probably due the results and probably due to the artificial selection of people at low risk of coronary myocardial infarction, 225 00:29:53,370 --> 00:30:00,340 the artificial nection of people at risk of these, this condition for hormone replacement therapy. 226 00:30:00,340 --> 00:30:10,010 And so the early results were reassuring, and it wasn't really until randomised controlled trials were done, in particular, 227 00:30:10,010 --> 00:30:22,830 a huge American study called the Women's Health Initiative that the full picture came out about the benefits and risks of hormone replacement therapy. 228 00:30:22,830 --> 00:30:27,880 And there was an increase small increase the risk of arterial disease. 229 00:30:27,880 --> 00:30:35,890 In that study, venous thromboembolism was confirmed. There was also some increase in the risk of breast cancer. 230 00:30:35,890 --> 00:30:39,760 There were, of course, beneficial effects on osteoporosis. 231 00:30:39,760 --> 00:30:52,320 But the balance of benefit and risk for many women looked looked unfavourable and pull in replacement therapy has been used less and less now. 232 00:30:52,320 --> 00:31:02,860 Now is this misused clearly for women who have severe menopausal symptoms, but they will rarely use it for more than perhaps three or four years, 233 00:31:02,860 --> 00:31:16,750 whereas in the past, some advocates claim that women should use HRT for 25 30 years ago, taking it until until they died, if you like. 234 00:31:16,750 --> 00:31:19,990 So the HRT story, too has been quite interesting. 235 00:31:19,990 --> 00:31:26,850 One to get back to your oral contraceptives any real difference between the so-called generations of pill? 236 00:31:26,850 --> 00:31:32,440 Oh boy, has that been a controversial one? 237 00:31:32,440 --> 00:31:37,840 Well, there's no doubt that the early, very high oestrogen or most, 238 00:31:37,840 --> 00:31:47,770 most high oestrogen pills that were in use when I did these MRC studies and the study in the 1960s, 239 00:31:47,770 --> 00:31:54,130 there's no doubt that they carried a higher risk than pills containing less oestrogen 240 00:31:54,130 --> 00:32:01,720 and that emerged fairly early on and let manufacturers to modify their formulations. 241 00:32:01,720 --> 00:32:12,530 The early formulations contained considerably more oestrogen that was necessary the the then the later, 242 00:32:12,530 --> 00:32:23,290 then which obviously emerged in relation to a new generation of progestogen as the after the after the initial pills, 243 00:32:23,290 --> 00:32:32,800 we used the early pills with the high dose of oestrogen new pills came in, which used low doses of oestrogen and indeed lower doses of progestogen. 244 00:32:32,800 --> 00:32:36,340 Those was sort of second generation pills. 245 00:32:36,340 --> 00:32:46,090 But then a new generation of pills appeared in the late 80s and the 90s, using New Progestogen as the third generation progestogen. 246 00:32:46,090 --> 00:32:58,390 And the argument about whether they carry a greater risk thrombosis and embolism in the second generation pills innocent still continues. 247 00:32:58,390 --> 00:33:10,090 Generally speaking, most people accept that they do carry a slightly higher risk of thrombosis and embolism than the second generation pills, 248 00:33:10,090 --> 00:33:16,090 and that the industry in particular still continues to fight this call. 249 00:33:16,090 --> 00:33:23,920 And because many of those progestogen as their babies and their more expensive pills, 250 00:33:23,920 --> 00:33:32,680 they would obviously refer them to be prescribed to the generic ones which make up the second generation pills. 251 00:33:32,680 --> 00:33:36,400 Now, obviously, medicines always on the move. 252 00:33:36,400 --> 00:33:45,820 You know, things are changing, and I've always thought that sometimes epidemiological studies may not have been asking a question that was important, 253 00:33:45,820 --> 00:33:53,470 such as aspirin and particularly vascular disease as people found aspirin and thrombotic. 254 00:33:53,470 --> 00:33:58,150 And there would have been a lot of good studies before that never asked about aspirin therapy. 255 00:33:58,150 --> 00:34:02,920 How often did that sort of thing that I'm I'm absolutely sure. 256 00:34:02,920 --> 00:34:20,120 Sure, that's true. The sometimes associations are sort i.e. you're chasing specific hypotheses, but certainly in epidemiological studies. 257 00:34:20,120 --> 00:34:28,910 Findings, unexpected findings may pop out of the data and the interest in the, you know, 258 00:34:28,910 --> 00:34:44,230 the protective effect of aspirin against myocardial infarction that was clearly apparent in the database held by Dr Hirsch or Jake in Boston. 259 00:34:44,230 --> 00:34:54,580 When I went when I went to work with him in 1972, that was one of the things that we had observed and it was because they had a big database. 260 00:34:54,580 --> 00:34:58,900 They had lots of diseases and lots of exposures. They were they had probes. 261 00:34:58,900 --> 00:35:03,190 Sophisticated programmes that look for drug disease associations. 262 00:35:03,190 --> 00:35:13,300 That was one that came out very consistently and interestingly enough, at that time, Peter Elwood, Cardiff was with Archie, 263 00:35:13,300 --> 00:35:21,430 Cochrane was running, I think, one of the very first trials of aspirin on the basis that it might protect against Mark. 264 00:35:21,430 --> 00:35:24,670 I thought I'm not quite sure where the idea would come up from there, 265 00:35:24,670 --> 00:35:30,160 perhaps from basic research on the effects of aspirin in vitro or something of that sort. 266 00:35:30,160 --> 00:35:38,740 And when we conveyed the results from Boston to Peter because I knew Peter was doing this study, 267 00:35:38,740 --> 00:35:42,610 he broke the code in his study and he found that he was showing usually a 268 00:35:42,610 --> 00:35:47,810 protective effect and in a way that's where the modern aspirin story started. 269 00:35:47,810 --> 00:35:53,020 Mm hmm. But there are there are certainly other chance effects in these. 270 00:35:53,020 --> 00:36:00,340 I mean, we now live in the days where there are enormous databases, huge numbers of diagnoses, 271 00:36:00,340 --> 00:36:05,920 huge numbers of exposures and quite a lot of information on confounding factors. 272 00:36:05,920 --> 00:36:12,130 And people can dredge data endlessly for drug disease associations. 273 00:36:12,130 --> 00:36:18,340 I mean, think of the way that people now dredged data for genetic associations. 274 00:36:18,340 --> 00:36:26,320 I mean, the endless nightmares they're looking for gene disease associations. 275 00:36:26,320 --> 00:36:33,970 And so one has to be on one's toes in trying to sort these things out. 276 00:36:33,970 --> 00:36:39,490 The social and community medicine, what's its relationship to epidemiology? 277 00:36:39,490 --> 00:36:45,460 Is it putting into practise epidemiological findings or is it more than that? 278 00:36:45,460 --> 00:36:56,950 Well, social and community medicine was my time when I was appointed as what was called the social medicine came from Alice Stewart's department. 279 00:36:56,950 --> 00:37:00,640 The third part was devoted to social medicine. 280 00:37:00,640 --> 00:37:14,260 The community bit came from the fact that community medicine was then a popular new name for what we might now call public health and used to do. 281 00:37:14,260 --> 00:37:20,740 And indeed. And so that's why we became social and community medicine. 282 00:37:20,740 --> 00:37:30,220 I mean, the those titles covered a very wide range of possibilities. 283 00:37:30,220 --> 00:37:39,190 Obviously, looking at the importance of social factors and behavioural factors in relation to disease would be an obvious one from the from the name, 284 00:37:39,190 --> 00:37:47,950 but also looking at the community based problems and looking at health care 285 00:37:47,950 --> 00:37:55,300 and using epidemiological methods to try and evaluate the benefits or risks, 286 00:37:55,300 --> 00:38:03,670 perhaps of different types of health care. And now all I personally was always interested. 287 00:38:03,670 --> 00:38:10,900 Most in the clinical side of epidemiology is most interested in investigating investigating 288 00:38:10,900 --> 00:38:17,530 diseases and what might cause them and what might prevent them and how they might be treated. 289 00:38:17,530 --> 00:38:22,630 But there were other people working within that discipline whose interest might be entirely 290 00:38:22,630 --> 00:38:31,600 on the organisation of health care and the evaluation of different types of health care. 291 00:38:31,600 --> 00:38:38,650 So it's it was it was a title that really covered a huge range of possible topics. 292 00:38:38,650 --> 00:38:49,150 But nonetheless, epidemiological principles, I think still underlie the different sorts of investigations were undertaken, 293 00:38:49,150 --> 00:38:53,680 whether they were in the health care area or in the more clinical area. 294 00:38:53,680 --> 00:39:02,080 So in a way to see if the difference between looking up to one person and looking after a flock and you know, 295 00:39:02,080 --> 00:39:09,190 some people put their emphasis on what happens to the folk. Others are concerned at the time with one particular. 296 00:39:09,190 --> 00:39:19,900 Well, absolutely right. And certainly, people concerned with the organisation of health care would be very concerned with the flock. 297 00:39:19,900 --> 00:39:24,950 But of course, using every person based epidemiological methods, 298 00:39:24,950 --> 00:39:33,210 the individual is of great importance to because you would have to be collecting data from and about individuals. 299 00:39:33,210 --> 00:39:43,240 You just mentioned here something that you might not bring up, but which I think is of some interest. 300 00:39:43,240 --> 00:39:49,630 And that is that when I was appointed to The Post in 1973, which I took up in 1974, 301 00:39:49,630 --> 00:39:58,600 the the chair and social media medicine in my job description was a charge to look at. 302 00:39:58,600 --> 00:40:12,490 The future of academic, academic, general practise good, and at that time, that was quite a difficult thing to be asked, 303 00:40:12,490 --> 00:40:26,590 especially apps in a medical school like Oxford, because I think general practise at that time was still regarded as somewhat second best. 304 00:40:26,590 --> 00:40:34,300 And there were people whom I shall certainly not name who thought there was no academic content in general practise, 305 00:40:34,300 --> 00:40:42,850 which of course, you and I know is absurd. So I did meet a certain amount of opposition in trying to further this. 306 00:40:42,850 --> 00:40:52,570 However, early on I got involved with an amazing chap called John Hessler, who was a general practitioner. 307 00:40:52,570 --> 00:40:55,960 And I think in Reading or Hindley, I think it's only fair. 308 00:40:55,960 --> 00:41:07,390 And John was such a dynamic force, and he and I worked really hard together to try and develop academic general practise, 309 00:41:07,390 --> 00:41:11,410 and we worked closely with the Royal College of General Practitioners. 310 00:41:11,410 --> 00:41:20,920 We got some money from the Dorothy McKenzie Trust, Royal College of General Practitioners and eventually with Rosemary Roos help. 311 00:41:20,920 --> 00:41:24,970 We got sufficient together to appoint a reader in general practise. 312 00:41:24,970 --> 00:41:29,830 And that, of course, was my dear friend and colleague Dr Coffey. 313 00:41:29,830 --> 00:41:36,940 Yes. And Godfrey and I worked very, very happily together over more than two decades, 314 00:41:36,940 --> 00:41:44,710 and academic general practise at Oxford now is really a very important part of the medical school. 315 00:41:44,710 --> 00:42:00,730 And so I do feel a little pride in a way that that was something we managed to achieve against a background of some opposition. 316 00:42:00,730 --> 00:42:04,690 And you know, I was going to ask you about the medical students with, 317 00:42:04,690 --> 00:42:11,290 did you would you see yourselves starting with general practise when the medical students went out to the general practitioners? 318 00:42:11,290 --> 00:42:16,480 Or were you more asking epidemiological questions about general practise? 319 00:42:16,480 --> 00:42:26,020 Oh, you know, I can't remember exactly what the medical students did before we began to get with 320 00:42:26,020 --> 00:42:32,950 with regard to general practise before Godfrey and I started to try and pull. 321 00:42:32,950 --> 00:42:38,650 You've started to appoint tutors and say, Well, we got some support from the dean of the school, more support from me. 322 00:42:38,650 --> 00:42:42,340 And then, of course, students went out to general practise. 323 00:42:42,340 --> 00:42:45,790 I think they did have an attachment before then. 324 00:42:45,790 --> 00:42:51,940 I'm not sure about that. But once we began to formalise it, 325 00:42:51,940 --> 00:42:58,600 then they were being taught important parts about aspects of disease or point of view in primary 326 00:42:58,600 --> 00:43:02,800 care and the interface between primary and secondary care and all those sorts of things. 327 00:43:02,800 --> 00:43:13,030 The girlfriend and I, we worked so closely together because the department community developed a social community. 328 00:43:13,030 --> 00:43:20,050 Medicine eventually became the brunt of community medicine, general practise and then the Department of Public Health and Primary Care. 329 00:43:20,050 --> 00:43:26,260 That's how it was when I retired in 2000, and Godfrey and I worked hand-in-glove. 330 00:43:26,260 --> 00:43:35,260 Godfrey, although an excellent clinician, was deeply interested in preventive medicine and in epidemiological methods, 331 00:43:35,260 --> 00:43:44,590 and we we produced Joint Teaching Programme for general epidemiology and public health and primary care. 332 00:43:44,590 --> 00:43:50,980 And so we would have common teaching programmes and often teach with general practitioners. 333 00:43:50,980 --> 00:43:54,430 And of course, we're were really great general practitioners around. 334 00:43:54,430 --> 00:44:00,160 I mean, Andrew Marcus Schofield, oh, people like that immensely, right? 335 00:44:00,160 --> 00:44:06,520 The general practitioners in Oxford and yes, Andrew Marcus and Theo Schofield being just two of them. 336 00:44:06,520 --> 00:44:16,900 Martin Lawrence, Yes, the late Martin Lawrence was, of course, another very bright star and many others too. 337 00:44:16,900 --> 00:44:26,380 Uh oh yes, we we have had very good people and we managed to appoint some remarkably good judges. 338 00:44:26,380 --> 00:44:32,350 And anyway, I think we did manage to establish the base. 339 00:44:32,350 --> 00:44:38,350 Was it subsequently developed into something very good, the general after? 340 00:44:38,350 --> 00:44:48,220 I'll just mention this very quickly. When I retired and Caulfield had retired before Michael Schofield, another I man, he was you sage. 341 00:44:48,220 --> 00:44:53,050 He was a Houseman when I was a student, so Godfrey and I knew each other well. 342 00:44:53,050 --> 00:44:58,350 When Godfrey retired and then I retired, David Weatherall was. 343 00:44:58,350 --> 00:45:11,410 Determined to separate general practise from from public health said the departments became separate and golfing, I opposed this. 344 00:45:11,410 --> 00:45:18,550 But David was wise and powerful and said the department did split. 345 00:45:18,550 --> 00:45:28,000 Martin Lawrence would probably become head of the advanced general practise, but he tragically died from cancer of the colon around that time. 346 00:45:28,000 --> 00:45:32,980 And instead, David meant it. Now David is a member of my department. 347 00:45:32,980 --> 00:45:38,710 He was trained in both community medicine and general practise, and he was. 348 00:45:38,710 --> 00:45:44,530 He was an amazingly effective head of departments, especially from the research point of view. 349 00:45:44,530 --> 00:45:53,020 And he really, I think, has built built general practise enormously during the 10 years that he was around, 350 00:45:53,020 --> 00:46:00,450 I suppose from about 2000 to 2010 or 2011 or whatever it was, David decided to retire at 60. 351 00:46:00,450 --> 00:46:09,060 Mm hmm. Uh, he's he's he said. He said to me, I think the time is right. 352 00:46:09,060 --> 00:46:14,320 The the the the effort I put in, as has left its mark. 353 00:46:14,320 --> 00:46:23,630 Yes. I always thought the business of the students living with the GP's that was was universe or was it just wasn't it? 354 00:46:23,630 --> 00:46:29,050 Wasn't it? But that's to be very, exactly the very. 355 00:46:29,050 --> 00:46:39,700 Now how much did you see the students? Otherwise, I mean, lectures, tutorials, what we we developed a course that was repeated six times a year. 356 00:46:39,700 --> 00:46:53,530 Right? Which was a two week module. And it would include it was small, obviously small group based and the the groups. 357 00:46:53,530 --> 00:46:58,540 The most of the times were about 12 people and perhaps 14 sometimes. 358 00:46:58,540 --> 00:47:01,070 And just doing you for that. 359 00:47:01,070 --> 00:47:09,310 Yes, we would have we would appoint a tutor for each group, although the tutor would bring in other people to lead sessions. 360 00:47:09,310 --> 00:47:14,320 And so some of whom would come from the NHS and some who come in the academic department. 361 00:47:14,320 --> 00:47:26,560 And we would have a series of seminars and exercises and some for a while goodly while public health visits to the. 362 00:47:26,560 --> 00:47:34,270 Some of our NHS colleagues were keen that we should continue with some public health visits to places like Far More Reservoir, 363 00:47:34,270 --> 00:47:39,100 for instance, and students like this, and drew a budget for a long, long time. 364 00:47:39,100 --> 00:47:49,570 They used to go to British Leyland and the they would have a session at Epsom Sessions and Occupational Health. 365 00:47:49,570 --> 00:48:01,420 And I always remember. I can't resist mentioning this, but at that time, British Leyland, as you probably know, this were building Rolls-Royce bodies. 366 00:48:01,420 --> 00:48:03,700 And for a long, long period, 367 00:48:03,700 --> 00:48:13,030 Rolls-Royce bodies were built there and they were enormously carefully filled with any deficit with the lead containing material. 368 00:48:13,030 --> 00:48:17,680 And around that area where they were doing that work on the bodies, 369 00:48:17,680 --> 00:48:25,480 it was a line beyond which no female of reproductive age was allowed to regress because of lead. 370 00:48:25,480 --> 00:48:31,160 And you can imagine the sort of general response of the delightful young lady. 371 00:48:31,160 --> 00:48:37,570 Is she now proof of being stopped at this words? 372 00:48:37,570 --> 00:48:42,550 That was a rule. So if you were, if you were going to keep that rule, then you wouldn't go to Bell. 373 00:48:42,550 --> 00:48:47,920 So we all accepted it and was it wasn't about lead poisoning there. 374 00:48:47,920 --> 00:48:51,920 I don't think so. I think it was all enormously carefully controlled. 375 00:48:51,920 --> 00:49:02,440 I think Bell had pretty good occupational health service and you're looking just sort of medical surgical grand rounds. 376 00:49:02,440 --> 00:49:08,920 I did go sometimes and very occasionally I might be on something. 377 00:49:08,920 --> 00:49:17,530 Uh, I was. I, as any question might sort of turn off. 378 00:49:17,530 --> 00:49:20,990 I have to admit I I used when I used to go, 379 00:49:20,990 --> 00:49:33,640 I had always felt some trepidation because I just wondered whoever was conducting the round where they might produce some impossible question. 380 00:49:33,640 --> 00:49:38,650 Because they might they might find a question about health service organisation, 381 00:49:38,650 --> 00:49:46,570 about health economics, about morbidity, mortality, well, distribution of disease. 382 00:49:46,570 --> 00:49:58,260 You know, anything would be regarded as fair game. And and there's, you know, one or two of our colleagues might not have been above throwing. 383 00:49:58,260 --> 00:50:14,520 Googly and bowling are good, and I'm just trying to formulate this, whether there is anything I should have asked you about that I haven't. 384 00:50:14,520 --> 00:50:31,050 Well, I'm I mean, obviously I did a lot of research and I did write a large number of research papers over the years and since my retirement, 385 00:50:31,050 --> 00:50:37,770 I've written another 40. Wow. Well, from our data, much of it from my. 386 00:50:37,770 --> 00:50:47,640 That's the Oxford FBA contraceptive study, which is a prospective study started in 1968, and I only terminated follow up in 2010. 387 00:50:47,640 --> 00:50:59,640 And it generated huge amounts of data about women's health generally, but also especially about contraception, about other aspects of women's health. 388 00:50:59,640 --> 00:51:13,500 So obviously, I spent a lot of time doing research the I think it might be worth mentioning that I became very, 389 00:51:13,500 --> 00:51:22,500 very involved with the breast cancer screening programme in. 390 00:51:22,500 --> 00:51:33,690 I was asked to chair the National Advisory Committee when at the time that the breast cancer screening programme was started, 391 00:51:33,690 --> 00:51:38,400 and I was asked indirectly by Sir Patrick Forrest, 392 00:51:38,400 --> 00:51:45,030 who has read this massive surgery in Edinburgh, who had done written the Forest Report, 393 00:51:45,030 --> 00:51:49,800 which is a report in which the government based their decision, set up a programme. 394 00:51:49,800 --> 00:51:53,700 So I chaired that committee and I also helped set up the programme. 395 00:51:53,700 --> 00:52:06,810 But the greatest praise for setting up the programme was undoubtedly go to Neil Grey meal and I would hand in glove. 396 00:52:06,810 --> 00:52:14,700 He was terrific. He's he's and he's a remarkable polymath, an amazingly good organiser. 397 00:52:14,700 --> 00:52:22,080 And I think the reason that we managed to set up a good programme is much more huge more than it is to me. 398 00:52:22,080 --> 00:52:28,140 Nonetheless, I had the frankly difficult task of chairing the National Advisory Committee, 399 00:52:28,140 --> 00:52:36,000 which advised the government and which also advised the field and right from the word go. 400 00:52:36,000 --> 00:52:46,350 The breast cancer screening was quite controversial and I was I chaired that committee for two, I think actually for 10 years the end. 401 00:52:46,350 --> 00:52:52,860 And then I was asked to chair the National Advisory Committee on the Cervical Cancer Screening to survive. 402 00:52:52,860 --> 00:52:58,230 The cancer screening has been around since the very early days of the 1960s, 403 00:52:58,230 --> 00:53:06,960 but it only became a proper programme end the 1980s and nationally supported it under control of the national director. 404 00:53:06,960 --> 00:53:14,160 My very dear colleague Juliette Patnaik, somebody else? 405 00:53:14,160 --> 00:53:19,950 This is my word for well over two decades, she's still director. 406 00:53:19,950 --> 00:53:29,550 Mm-Hmm. Terrific. Terrific director. And I think it was really she that got me asked to chair that one. 407 00:53:29,550 --> 00:53:33,240 And that that was pretty tricky, too. 408 00:53:33,240 --> 00:53:38,160 I mean, one of the decisions we made, for example, we made many, 409 00:53:38,160 --> 00:53:47,460 but one that we made was the decision that the national programme shouldn't begin until age 25 rather than age 20. 410 00:53:47,460 --> 00:53:55,800 And if you actually look at the data and look at the statistics, that is the most sensible thing to do in both not only financially, 411 00:53:55,800 --> 00:54:01,710 but much more importantly, much more importantly in terms of benefit risk. 412 00:54:01,710 --> 00:54:05,190 And that was grossly hugely controversial thing. 413 00:54:05,190 --> 00:54:13,620 And I mean, we we got we were involved during the time I worked as chairman of those committees, and I put a lot into it. 414 00:54:13,620 --> 00:54:21,300 We were involved with all sorts of difficult questions. Then to my amazement, I was asked to chair. 415 00:54:21,300 --> 00:54:26,830 I think it was in 2006, well into retirement. 416 00:54:26,830 --> 00:54:32,420 I was asked to chair the National Advisory Committee on Screening for Bowel Cancer. 417 00:54:32,420 --> 00:54:40,260 I wasn't an expert on bowel cancer, but I did know something about screening and I did that for three years, the first four years. 418 00:54:40,260 --> 00:54:54,210 But I decided when I hit 75 that I wouldn't chair any more national programmes because not just because young people should do these things, 419 00:54:54,210 --> 00:54:58,130 but also because one becomes a little nervous. And this one is. 420 00:54:58,130 --> 00:55:06,810 Using one's onions unknown to oneself, just I think it's the danger of going on for too long. 421 00:55:06,810 --> 00:55:11,360 Yeah, and I was really rather determined not to do that. 422 00:55:11,360 --> 00:55:19,760 But those screening programmes, they I mean, they were enormously interesting. 423 00:55:19,760 --> 00:55:28,640 I put a lot into them. They have been they've certainly the breast cancer screening programme has proved to be quite a controversial programme. 424 00:55:28,640 --> 00:55:35,840 Lesson one time is around. Nothing to do with me that, you know, the benefit and risk is being questioned more in recent years. 425 00:55:35,840 --> 00:55:42,770 And but that it did did form quite quite an important part of my work. 426 00:55:42,770 --> 00:55:51,350 I've stressed W.H.O. I did endless work on all sorts of committees in the reproductive field for W.H.O. 427 00:55:51,350 --> 00:55:59,330 The other thing I did is put a lot of effort in is that I was a member of the Royal Commission on Environmental Pollution. 428 00:55:59,330 --> 00:56:08,540 Richard Doll was a member when he retired. He suggested I should serve as if I didn't know enough to do it, and I agreed. 429 00:56:08,540 --> 00:56:11,480 Now, at the time I joined it, 430 00:56:11,480 --> 00:56:22,010 it was hugely rewarding because it was chaired by Richard Southwood and I declare himself with our vice chancellor and Dick, 431 00:56:22,010 --> 00:56:26,860 who is just terrific, so wonderful to work with. 432 00:56:26,860 --> 00:56:30,470 Another sadly dick has died, of course, as well. Yes. 433 00:56:30,470 --> 00:56:43,550 And I said to such to complete rotations of the Royal Commission, Environmental Pollution and Dick chaired the first one. 434 00:56:43,550 --> 00:56:47,930 And I mean, the second one was chaired by somebody else. But it was also very interesting. 435 00:56:47,930 --> 00:56:51,590 But dick, it was just so great to work with Dick, 436 00:56:51,590 --> 00:57:02,120 and he became a really rather close friend and somebody who I hope there's always been a bit of a hero for me got involved with this. 437 00:57:02,120 --> 00:57:07,850 He did, which it said it would get involved the AC. 438 00:57:07,850 --> 00:57:14,910 I think that was a pretty uncomfortable thing for him. I think everybody who was involved is he found that pretty uncomfortable. 439 00:57:14,910 --> 00:57:19,610 And then McRae, was he NHS employed? 440 00:57:19,610 --> 00:57:31,790 Yes, Neal. Yes, he he came as a public health doctor and he was he was NHS employed throughout. 441 00:57:31,790 --> 00:57:35,990 How much did you have to do with, say, I had it together over anybody else and. 442 00:57:35,990 --> 00:57:50,630 Yes, I I felt very I felt it very important to work with and to help my NHS colleagues as much as I could, 443 00:57:50,630 --> 00:57:55,880 even though they were much more concerned with the organisation of health care. 444 00:57:55,880 --> 00:58:06,530 But obviously, they were concerned with preventive medicine and infectious diseases and vaccines, preventative vaccines, maternal and child health. 445 00:58:06,530 --> 00:58:12,110 But that health care organisation was a very dominant problem for them, 446 00:58:12,110 --> 00:58:20,450 and I had the again, the tremendous pleasure of working very closely with Alex Gatherer. 447 00:58:20,450 --> 00:58:31,340 He also died recently, and if he fell ill to a good age, he went on working for W.H.O. for a long time right after his retirement. 448 00:58:31,340 --> 00:58:38,870 And I went to a lot of his meetings and I tried try to work with the the practitioners, 449 00:58:38,870 --> 00:58:49,580 the NHS practitioners and I used to go to regional meetings and so on and so forth, and I think I managed to make a useful contribution. 450 00:58:49,580 --> 00:58:58,220 I hope so. And of course, the other person I work with very closely in the same way was Rosemary Booth and afterwards, Ronnie Pollock. 451 00:58:58,220 --> 00:59:06,050 Yes. And again, you know, Rosemary, another great Oxford style and a wonderful lady. 452 00:59:06,050 --> 00:59:10,610 Tremendous to work with. Always immensely kind to me. 453 00:59:10,610 --> 00:59:15,470 I remember when I first was first appointed, Rosemary said. 454 00:59:15,470 --> 00:59:20,900 She said actually my first script, she said, laughing, but she came to see me. 455 00:59:20,900 --> 00:59:29,870 And she said I thought, who is is very young at home and young man, she is yours. 456 00:59:29,870 --> 00:59:33,360 I was quite young and I think she didn't know me very well. 457 00:59:33,360 --> 00:59:45,230 And then we become 35. And I was I was appointed at 37 right and the rosemary was terrific throughout. 458 00:59:45,230 --> 00:59:51,110 And it was said that region gradually over the years lost its influence. 459 00:59:51,110 --> 00:59:58,070 Well, you will know, Derek, how much Rosemary contributed towards the technical school and the things. 460 00:59:58,070 --> 01:00:01,940 We try to do what would you collaborate with their own? 461 01:00:01,940 --> 01:00:04,970 And what sort of things would you be doing? 462 01:00:04,970 --> 01:00:16,550 I went I went to Rosemary's Regional Medical Office at meetings at which many planning issues would be discussed. 463 01:00:16,550 --> 01:00:24,590 Most of them organisational and managerial, but some of them more clinical. 464 01:00:24,590 --> 01:00:27,950 And I managed to contribute to the quilt, 465 01:00:27,950 --> 01:00:43,250 the quite a few the things that they were considering and to offer some epidemiological input to population matters that would come up at the meeting. 466 01:00:43,250 --> 01:00:48,420 I worked very closely for the Regional Medical Research Committee. 467 01:00:48,420 --> 01:00:56,330 I used to chair their all their committees and offer advice advice to the region. 468 01:00:56,330 --> 01:01:04,490 Rosemary would often ask me for my view on some steps that she was going to take in relation to 469 01:01:04,490 --> 01:01:11,100 the clinical school and one she she often used to ring me up or ask me if I'd come and see her. 470 01:01:11,100 --> 01:01:20,420 We often used to drink a sherry together, Rosemary USU manager, producer, Sherry late afternoon, and we would we would chat, chat about things. 471 01:01:20,420 --> 01:01:25,880 But equally, Rosemary is very interested in what we were doing. 472 01:01:25,880 --> 01:01:33,940 She always wanted to know what we were working on, and she was very interested, for instance, in breast cancer research. 473 01:01:33,940 --> 01:01:38,360 And of course, she eventually died from the disease. 474 01:01:38,360 --> 01:01:43,340 And she so so there was a lot of interaction quite well. 475 01:01:43,340 --> 01:01:49,790 It was fairly informal, but the regional medical officer meetings and the assembled armadillo meetings, 476 01:01:49,790 --> 01:01:52,790 regional and district medical officer meetings, 477 01:01:52,790 --> 01:02:03,240 I used to attend faithfully and a lot of I think what I managed to contribute would be through that sort of medium and. 478 01:02:03,240 --> 01:02:15,870 U.S. general travelling around the world, presumably, well, the a lot of the things I was working on were very topical when I was working on them, 479 01:02:15,870 --> 01:02:22,650 so I was invited to give talks at many conferences in different parts of the world. 480 01:02:22,650 --> 01:02:33,750 And also, I became a consultant to their projects, also collaborative drug surveillance programme, and I was there as a consultant for many years. 481 01:02:33,750 --> 01:02:46,470 I used to go two or three times a year to work with them for a week, and W.H.O. certainly generated some interesting interest in foreign travel. 482 01:02:46,470 --> 01:02:51,960 So yes, I think I did my share of travelling around the globe. 483 01:02:51,960 --> 01:02:57,090 Did you get involved with nutritional side of things in there? 484 01:02:57,090 --> 01:03:11,210 Well, the the answer to that is not personally to any great extent, but you will know, Derrick, that it was a considerable interest in my department. 485 01:03:11,210 --> 01:03:22,620 Yes. And I must admit something else that I really tried hard to do in my department was to be really, 486 01:03:22,620 --> 01:03:26,220 genuinely interested in what my colleagues were doing. 487 01:03:26,220 --> 01:03:33,450 And I wanted to know what they were doing, and I wanted to try to support them and encourage them. 488 01:03:33,450 --> 01:03:48,660 So I certainly would discuss will be get involved in that area when plans were being drawn up, say by somebody like Jim Manuel or Andrew Neil. 489 01:03:48,660 --> 01:03:59,490 People who had an interest in diet and more than one DPhil student in our department researched in the nutritional area. 490 01:03:59,490 --> 01:04:08,790 So although I didn't do any sort of hands-on work in that area myself, it was certainly an important interest in the development. 491 01:04:08,790 --> 01:04:13,530 You must have supervised a lot of details. I did. That's great. 492 01:04:13,530 --> 01:04:28,500 Helpful is it's hard work. But what I said when I gave a little speech at my departure dinner was that if I look back on my life, uh, 493 01:04:28,500 --> 01:04:36,720 professional life, then I would have to say that the most rewarding thing was working with the DPhil students. 494 01:04:36,720 --> 01:04:40,770 The We had wonderful DPhil students. 495 01:04:40,770 --> 01:04:47,280 We were blessed with many of them being Rhodes scholars. 496 01:04:47,280 --> 01:04:52,620 I mean, David Skegg been, for example, but with them in many, many, many others. 497 01:04:52,620 --> 01:05:00,030 And they turned out to be such amazing people and such a pleasure to work with. 498 01:05:00,030 --> 01:05:13,170 And it was possible they would work often on something that either I myself wanted to pursue or something my department wanted to pursue. 499 01:05:13,170 --> 01:05:20,400 Because, as you know, DPhil students always have to find a project. Some know exactly what they want and they come, but most don't. 500 01:05:20,400 --> 01:05:26,910 And so it was possible to work very, very closely with the Hmong, often on something very close to the heart. 501 01:05:26,910 --> 01:05:38,190 And I used to see my fellow students frequently, and I just great enjoyed working with them. 502 01:05:38,190 --> 01:05:49,710 And almost all the ones we had did remarkably well and and have have gone to interesting posts in different parts of the world. 503 01:05:49,710 --> 01:05:56,010 I can think of only two who for whom it didn't work out. 504 01:05:56,010 --> 01:06:34,290 One was a young man in South Africa who I think was just somehow overwhelmed by the complexity of what. 505 01:06:34,290 --> 01:06:37,800 But again, is the Oxford environment involved in that? 506 01:06:37,800 --> 01:06:51,060 Well, I think I think both those people go as much support as could be offered both in the parliament and more importantly, from colleges. 507 01:06:51,060 --> 01:06:57,840 I think I think in both cases, the colleges did everything they could, but the load on them is, Oh, really? 508 01:06:57,840 --> 01:07:06,510 Oh gosh, yes. I mean, people come from a closely supervised world and really act. 509 01:07:06,510 --> 01:07:10,560 Ultimately did did their own patch. 510 01:07:10,560 --> 01:07:22,360 And and I think it's for some people who come perhaps from the heavily supervised activity or from a very underdeveloped activity, 511 01:07:22,360 --> 01:07:26,070 see the kind of environment they meet. 512 01:07:26,070 --> 01:07:32,310 And also it could be very difficult. But mostly they were just fantastic. 513 01:07:32,310 --> 01:07:42,690 They didn't walk on those roads enough. Of course, nothing to build is great, and some of them came on other funds, often from their own country. 514 01:07:42,690 --> 01:07:47,250 And they were they were all terrific, really. 515 01:07:47,250 --> 01:07:52,020 I mean, even those two tragedies they mentioned to you, they were there. 516 01:07:52,020 --> 01:07:57,420 Just very sad. Yes. How many people did you have to reject who were applying to do it? 517 01:07:57,420 --> 01:08:01,750 Do you feel? Erm, 518 01:08:01,750 --> 01:08:15,930 we if we had gone as far as getting to the Applications Committee of the Clinical Medicine Board and being accepted by the Applications Committee, 519 01:08:15,930 --> 01:08:20,790 we would certainly never define rejection. So is that where the main selection occurred? 520 01:08:20,790 --> 01:08:32,550 You feel the the where I first explain where more people would often approach you in the format and and you would encourage them. 521 01:08:32,550 --> 01:08:36,660 I think in fact, we reject we rejected very, very few people. 522 01:08:36,660 --> 01:08:41,490 I would say most people who wanted to come and work with us, we accepted. 523 01:08:41,490 --> 01:08:44,730 I mean, obviously, we absolutely lapped them up. 524 01:08:44,730 --> 01:08:50,040 If you were a Rhodes scholar or another Dominion scholars, we knew they would be great. 525 01:08:50,040 --> 01:09:03,060 But but the majority of the others came often with funds from home and they came with good credentials. 526 01:09:03,060 --> 01:09:10,290 And actually, we didn't have too many people, a handful, perhaps. 527 01:09:10,290 --> 01:09:19,470 What else would you like to say? Well, I know you've done very well. 528 01:09:19,470 --> 01:09:26,700 I mean, I think I I think I ended up doing what suited me best. 529 01:09:26,700 --> 01:09:37,320 Mm-Hmm. And because I was able to combine an interest in methods and solving problems 530 01:09:37,320 --> 01:09:49,860 with with with medicine and clinical medicine has always been close to me, 531 01:09:49,860 --> 01:09:56,400 and my interests have always been quite been close to clinical medicine. 532 01:09:56,400 --> 01:10:01,090 And that's tended to be the sole variable, which most of my work has been done. 533 01:10:01,090 --> 01:10:07,050 But how I would have worked out as a clinician, I don't know. 534 01:10:07,050 --> 01:10:22,920 I I have a feeling that I might have been troubled by being too conscientious and just kind of worrying 535 01:10:22,920 --> 01:10:35,660 too much about the people looking after and whether I'd really done the best I possibly could for them. 536 01:10:35,660 --> 01:10:49,430 I think I think if you if you consider the people in surgical practise, I I never really thought of being a surgeon. 537 01:10:49,430 --> 01:11:03,950 People who succeed in surgery tend to have pretty robust personalities, and I don't think that they can survive if they take too much anxiety. 538 01:11:03,950 --> 01:11:12,980 And perhaps no doubt. I agree. That doesn't mean to say that they're not terrific people. 539 01:11:12,980 --> 01:11:20,330 Many of them are, and I count many amongst my dear friends. 540 01:11:20,330 --> 01:11:32,360 That's a bit less true, perhaps in on the side bets as opposed to surgery, although that can be. 541 01:11:32,360 --> 01:11:44,220 There's also can be very harrowing. So I think maybe taking into account my personality and my interests and the way things panned out, 542 01:11:44,220 --> 01:11:51,380 I've been very, very fortunate in the way my my career develops. 543 01:11:51,380 --> 01:12:04,100 And you mentioned Dennis Stewart. And I was just thinking epidemiology would seem a subject that women aren't so notable in number and achievement. 544 01:12:04,100 --> 01:12:14,060 Well, general practise, of course, is something that attracts some particular a lot of women on our general practise and the ABCs of GP's, 545 01:12:14,060 --> 01:12:19,920 the quite a lot of people want women went into public health. 546 01:12:19,920 --> 01:12:34,520 Yes, and yes it did. Indeed. And certainly a lot of my fellow students or women ride around and they were outstandingly good. 547 01:12:34,520 --> 01:12:38,000 I mean, if you if you look at if you look around now, 548 01:12:38,000 --> 01:12:48,020 I suppose the most outstanding woman you would pick out is Valerie Burrell, who who is now Dame Valerie Burrell. 549 01:12:48,020 --> 01:13:04,490 And she is. She directs the Cancer Epidemiology Research Unit and is has done lots of really very good work. 550 01:13:04,490 --> 01:13:09,660 There are a lot of people in her unit are women, but a lot of know. A lot of my colleagues were always women. 551 01:13:09,660 --> 01:13:18,710 I think the public health and epidemiology do it to appeal to women, and I think that for some of them, 552 01:13:18,710 --> 01:13:26,240 it it might offer a career in which they were less like to be called out a bit in the middle of the night. 553 01:13:26,240 --> 01:13:30,760 And we have to be realistic about this if you have three small children. 554 01:13:30,760 --> 01:13:33,650 It's not great to be called up in the middle of the night, 555 01:13:33,650 --> 01:13:41,240 but I don't see in that in any way, depreciating the tremendous contribution that women make. 556 01:13:41,240 --> 01:13:47,090 And I think I have had the privilege to encourage and bring along quite a few. 557 01:13:47,090 --> 01:13:52,580 And did did you get involved in prostate cancer at all? 558 01:13:52,580 --> 01:13:56,810 Not, not directly. No, it wasn't. 559 01:13:56,810 --> 01:14:07,730 The breast, cervix, endometrium and ovary were the Kansas that I was most interested in, but I always, you know, 560 01:14:07,730 --> 01:14:17,900 kept an eye on the male reproductive cancers to testicular cancer and in particular, prostate cancer. 561 01:14:17,900 --> 01:14:28,460 And obviously, I've been close to the question of prostate cancer screening because that's a hugely 562 01:14:28,460 --> 01:14:37,130 contentious area and an area which is not followed in present in the United Kingdom. 563 01:14:37,130 --> 01:14:42,890 The it is the opinion that the National Screening Committee and I agree with this. 564 01:14:42,890 --> 01:14:53,580 The risks still outweigh the benefits using PSA as the as the substance you're measuring. 565 01:14:53,580 --> 01:14:58,160 We need better screening methods for prostate cancer. 566 01:14:58,160 --> 01:15:06,380 It may be that screening by PSA can save a few lives from prostate cancer, 567 01:15:06,380 --> 01:15:16,500 but at a terrible cost in terms of the diagnosis of cancers that would never have killed person and had the disease. 568 01:15:16,500 --> 01:15:25,520 The people who undergo radical investigation and often radical treatment and you know that it is the false positives as well as false negatives, 569 01:15:25,520 --> 01:15:30,230 of course, that have to be considered so carefully in any screening programme. 570 01:15:30,230 --> 01:15:33,590 And there's a big, big problem for prostate cancer. So. 571 01:15:33,590 --> 01:15:41,720 I've I've certainly had less interest in the aetiology of prostate cancer, not as much to say about it even now, 572 01:15:41,720 --> 01:15:52,610 but certainly in early diagnosis, the screening an isolated incident that involved some extent with that, unless you say something I don't know. 573 01:15:52,610 --> 01:15:56,580 And there's virtually no one else goes to be questioned. 574 01:15:56,580 --> 01:16:02,920 But Richard Dolan is to it. They had different views. 575 01:16:02,920 --> 01:16:13,820 Yes, I think it's well known that Richard and Alice didn't see each other. 576 01:16:13,820 --> 01:16:20,300 I mean, Alice was clearly an extremely evil woman, and she had, of course, 577 01:16:20,300 --> 01:16:27,410 clinical origins she worked with which, you know, do you know, I think you see LJ LJ here. 578 01:16:27,410 --> 01:16:31,970 And so her clinical knowledge was was good. 579 01:16:31,970 --> 01:16:46,290 She made notable discoveries about the effects of radiation in utero, especially in relation to leukaemia. 580 01:16:46,290 --> 01:16:52,910 I'm absolutely sure really why she and Richard didn't see eye to eye. 581 01:16:52,910 --> 01:16:58,460 I'm quite sure the underlying conflict. 582 01:16:58,460 --> 01:17:04,830 But there's certainly there was something there. 583 01:17:04,830 --> 01:17:09,350 And it's true. The gossipy question it may be, but it certainly there was. 584 01:17:09,350 --> 01:17:16,340 I mean, so in your view, she wasn't pushing evidence that she shouldn't have been and sort of exaggerating. 585 01:17:16,340 --> 01:17:22,880 Well, of course, you know. Oh, well, there may have been an endless argument about the effects of very low dose radiation, 586 01:17:22,880 --> 01:17:31,550 very innocent people still under the influence of very low dose ionising radiation in relation to cancer. 587 01:17:31,550 --> 01:17:36,880 And certainly, I think Richard and Alice had different views on that. 588 01:17:36,880 --> 01:17:42,770 You know, it may have been in part that I may say in this position, 589 01:17:42,770 --> 01:17:50,600 when I was appointed, I obviously had to see how it was I was to give her department. 590 01:17:50,600 --> 01:17:59,520 And at first I did sense of hostility, but it didn't last. 591 01:17:59,520 --> 01:18:08,270 You know, I'm sure she soon, soon soon became friends and she was actually very kind to me and helped me, which she could. 592 01:18:08,270 --> 01:18:12,980 She was a very, very tough lady and a very remarkable lady, Alice. 593 01:18:12,980 --> 01:18:17,120 And in some ways, I suppose you could say the hard act to follow. 594 01:18:17,120 --> 01:18:23,210 But of course, her involvement Michael was totally different from a different world and different. 595 01:18:23,210 --> 01:18:34,670 Absolutely. Totally different. It is. And so they were never they would set out to make it work. 596 01:18:34,670 --> 01:18:44,330 You couldn't make it completely direct. Yes. And she, of course, had followed while while he was a distinguished, distinguished person. 597 01:18:44,330 --> 01:18:48,920 Yeah. Well, Martin, that's terrific interview. Thank you very much indeed. 598 01:18:48,920 --> 01:18:53,074 We'll have to see it's a movie.
