Coming up today:听 Getting the latest treatments - the Chairman of NICE, David Haslam, is here to explain why he thinks NHS patients could learn a thing or two from their pushier American cousins.

听

Prostate cancer 鈥� we take a closer look at a new technique for improving its diagnosis.

听

Clip

If you live long enough you鈥檙e probably going to get prostate cancer.听 My own risk, sitting here talking to you, is about 50% and yet my chances of dying of it are only about one in 30 or 3%.听 And so the art is really discriminating between the cancers that we鈥檙e going to get anyway and won鈥檛 affect us if left alone and the cancers that are likely to progress and perhaps could cause a death.听 This isn鈥檛 about diagnosing prostate cancer 鈥� that鈥檚 a futile exercise 鈥� this is about diagnosing clinically significant prostate cancer with precision.

听

Porter

More from that surgeon a little later.听 And if you鈥檝e been referred following a raised PSA blood test then I suggest you don鈥檛 miss it.

听

But first electronic cigarettes and the announcement by the government that it plans to make it illegal to sell them to anyone under the age of 18. 听Their advertising could soon be restricted too amid fears that vaping is a gateway to smoking for younger people. 听So is the government right to be concerned?

听

Well to help us find out I am joined by three leading lights in the field:听 Martin McKee is Professor of Public Health at the London School of Hygiene and Tropical Medicine;听 Professor Gerard Hastings is from the Centre for Tobacco Control Research at the University of Stirling and Robert West is Professor of Health Psychology at University College London.

听

Robert, who is using e-cigarettes and how?

听

West

Eight five per cent of people, when they start to use them, use them as an attempt to stop smoking.听 And the way it seems to us, particularly when you look at the kind of people who are using them, they look awfully like the people who would otherwise use the licensed nicotine products 鈥� nicotine patch and so on.听 So that鈥檚 when they start to use them.听 However, as we know, stopping smoking is very difficult so what you find is a substantial proportion 鈥� most of them relapse 鈥� and so what you end up with at any one time it is cutting down that dominates.

听

Porter

Martin McKee for you have these been a welcome addition to the market?

听

McKee

What concerns me is the way that the tobacco manufacturers have got in on the market.听 They鈥檝e suddenly realised that this is an opportunity for them and they鈥檙e really pushing them very hard, they鈥檙e taking over the small manufacturers who produced them early on and I think they鈥檙e doing that for a number of reasons.听 One, they鈥檙e terribly concerned about what we call the denormalisation of smoking, the fact that smoking is no longer socially acceptable.听 The tobacco industry has really done very well at promoting smoking by getting smoking into movies, for example, but by using e cigarettes they can get the images which look exactly like smoking into pop videos for kids, into movies, you saw people at the Golden Globes smoking 鈥� vaping 鈥� with the e cigarettes, that鈥檚 renormalising the imagery.听 But I think the other thing is the cigalites, which are objects which look for all the world like cigarettes, it鈥檚 not that they just look a bit like cigarettes, they look exactly like cigarettes.听 And when you鈥檝e got bans on cigarette advertising you can put these things all over the place and most people looking at them from a distance will say 鈥� those are cigarettes.听 So you鈥檙e circumventing the bans that have been very effective.

听

Porter

Gerard Hastings?

听

Hastings

I think first of all I would agree with Robert 鈥� the potential here for a great deal of good if we can get adult smokers to switch from tobacco to electronic cigarettes, although we鈥檙e still in the early days of working out what e cigarettes do they鈥檙e surely not as dangerous as real cigarettes, so that鈥檚 got to be a good thing.听 But Martin is also right 鈥� the fact that they imitate cigarettes so closely is dangerous because imitation is the sincerest form of flattery.听 So we鈥檝e got these products being used, almost like decaffeinated coffee but decaffeinated coffee only exists because there鈥檚 real coffee and real coffee is the real McCoy.听 There鈥檚 a great danger that the subtext of all this activity, albeit is generating some public health gains, will involve some big steps backwards 鈥� the renormalisation of the use of nicotine on a habitual basis 鈥� that it could create enormous problems.听 I just don鈥檛 think we know, so I think we鈥檝e got to tread carefully.

听

Porter

Do we know what鈥檚 happening to overall consumption?听 I mean it must be a difficult thing to work out but looking at the number of cigarettes smoked plus e cigarettes smoked, I mean are the e cigarettes additional?

听

West

Yeah we do know, I mean this is the great advantage of being able to track these things and there鈥檚 no other country in the world that has the kind of data that we鈥檝e got.听 This is where Gerard and Martin and I might part company, at least a little bit, is while I agree totally with the theoretical risk but if we look at where the evidence is at the moment what we鈥檙e seeing in the last two years since these products have come on to the market in a big way is an acceleration in the rate of smoking cessation, the rate of use of these e cigarettes among people who are non-smokers and haven鈥檛 smoked is about point five of one per cent, the rate at which people are trying to stop has gone up but the motivation rate has gone up and the success rate has gone up.听 So at the moment the signs are in a positive direction.听 Having said that I completely agree that this could be a false dawn and it may go the other way.

听

Porter

So it looks like people are giving up, Martin, and not many people are taking up these e cigarettes?

听

McKee

Well we do have some evidence from the United States following up children, that there are children who are moving into e cigarettes and potentially then on to real cigarettes but the numbers are small.听 And remember that the industry is producing these really targeted at kids 鈥� the flavourings that are in them 鈥� bubble-gum flavour 鈥� that鈥檚 not a flavour for adults is it?听 So they鈥檙e clearly being pushed at children.

听

Hastings

Bear in mind that the tobacco market is utterly dependent upon recruiting children 鈥� 88%, according to the Surgeon General鈥檚 report 鈥� 88% of smokers start in their childhood.听 So you cannot run a market in this area without long term recruiting children.

听

McKee

And I think if you look at pop videos 鈥� anyone might want to look at the latest Lily Allen video where e cigarettes are very prominent, that is clearly targeted at kids.听 But I think it is undoubtedly true that people are cutting back on what they鈥檙e smoking but remember that the real gains, particularly in terms of the effect on heart disease, are from giving up altogether.

听

Porter

Well that鈥檚 one concern that I have that actually what people are doing is that they鈥檙e using e cigarettes during the day, when they can鈥檛 smoke at work or they can鈥檛 smoke in the house, but it enables them to perpetuate their smoking habit, so when they go out at the weekend or at other times.听 Do we have any evidence鈥�.?

听

West

Yes and that is the risk with the cutting down message generally.听 What the evidence shows with licensed products 鈥� we haven鈥檛 got evidence for e cigarettes yet but we will have 鈥� but what with licensed nicotine products what the evidence shows is that people who cut down with them when you follow them up a year later you find that lo and behold they鈥檝e actually stopped.听 It somehow is a gateway to stopping.听 Now we don鈥檛 know whether that will be the case with e cigarettes, time will tell, so I completely agree that the cutting down is not in itself a goal but it may be a step to quitting.

听

Hastings

The other player of course in this debate is the market and what the commercial operators, whether they be tobacco companies or small e cigarette companies will do, and the only thing we know for certain there is that they will chase the money, they will do what is most profitable not what is best for public health.

听

McKee

And if I can pick up on that I think we really need to get inside the mind of the tobacco industry here, they are now taking over many of the e cigarette manufacturers and they鈥檙e marketing them very heavily, the advertisements are everywhere, but if they really wanted to get them out to be used in large amounts they would cut the price.听 But if you want to buy an e cigarette refill you鈥檙e talking about 拢8 a go if you buy it off the internet.听 And remember there鈥檚 no tax to be paid on that.听 These are being produced in China, they could be produced for 10-20p, so if they had a real strategy of increasing uptake they would be almost giving them away, they鈥檙e not doing that.听 And many of us believe that what they want is just to have a few of them on the market to justify being able to plaster their advertisements all over everywhere because they鈥檙e really advertising cigarettes, they鈥檙e not actually advertising e cigarettes.

听

Porter

Well this was something that struck me 鈥� I saw a television advert and it was a flashback, took me back 30 years, of a couple of blokes sharing moments together and they ended up sharing an e cigarette together and I thought it was weird.

听

Hastings

It鈥檚 worth saying Mark that we did a study last year looking at exactly this, looking 鈥� did an audit of all the marketing that鈥檚 going on for e cigarettes and it absolutely is exactly as you say it鈥檚 a flashback to the 1960s and 鈥�70s when tobacco advertising was still very free and easily available, the same sorts of pictures for lifestyle claims, trendiness, coolness, sport sponsorship, celebrity endorsement, pop videos 鈥� all these things that tobacco industry in the past would have jumped on as fast as it could and did are now being used for e cigarettes.

听

West

There is one thing I鈥檇 like to say, just to extend this, and that is one of the things that we may have as an opportunity here 鈥� and I completely agree about the issue of marketing, actually I don鈥檛 think they should be allowed to be marketed 鈥� but one of the things about the denormalisation argument is really about the things that look like smoking.听 Now increasingly with the second generation products and even more so with the third generation products what you鈥檙e getting is products who actually look nothing like cigarettes but they鈥檙e much more effective nicotine delivery systems.听 And so there is a chance that what we鈥檝e done is to essentially to break the ice with the idea of a nicotine product which could be attractive but isn鈥檛 smoking.听 Now I agree that that鈥檚 theoretical as well but it offers an opportunity.

听

Porter

You鈥檙e talking about devices that look like stainless steel mini pipes and all sorts鈥�

听

West

Sonic screwdriver.

听

Hastings

But this is really quite scary territory isn鈥檛 it.听 If you recall for a moment the Hippocratic oath 鈥� first do no harm 鈥� and we鈥檙e jumping in with this and I think we鈥檝e got a very odd situation in the UK now where the medicines鈥� regulator has said these things need regulating but actually we鈥檙e not going to do anything for three years. And I think absolutely 100% with Robert on this 鈥� the marketing of these is extremely dangerous, we need to control that.

听

Porter

You鈥檙e implying that the marketing is aimed at children with flavours and the coolness鈥�

听

Hastings

I wouldn鈥檛 get into the 鈥� whether it鈥檚 actually aimed at them or not, whether it鈥檚 manslaughter or murder the point is that it will appeal to children.

听

Porter

Well okay, so it鈥檚 appealing to children, we know that some people are taking up de novo, children are taking this up for the first time, is there any evidence that they go on to smoke?

听

West

No we don鈥檛 know that yet and that is absolutely the $64,000 question.

听

Hastings

鈥� that is an absence in our data set because your survey鈥檚 with adults isn鈥檛 it?

听

West

Oh yeah we start at 16 but there are other studies going on.听 But it鈥檚 early days鈥�

听

Porter

Martin McKee, you鈥檙e champing to get in there.

听

McKee

Well because in public health of course we endorse the precautionary principle and if there is a degree of uncertainty we should take precautions.听 We should now be thinking about do we really want them at all.听 If we are going to have them as a nicotine delivery device, first of all, there are other ways of getting nicotine in, there are aerosol sprays, there are patches, there are other ways which do not have the imagery associated with smoking.听 But I too would ban advertising entirely, I would have them in plain packaging and I would ban the use of flavours.听 There is no excuse for having bubble-gum, cotton candy 鈥� things like that 鈥� and I would also make sure that they鈥檙e kept away from 鈥� as happens in the US 鈥� they鈥檙e put among the sweets at the checkout.

听

Porter

Professors Martin McKee, Gerard Hastings and Robert West 鈥� thank you all very much. And moves to restrict advertising are currently out for public consultation.

听

Now, some feedback from last week鈥檚 item on difficulty stopping PPIs 鈥� the family of potent stomach acid reducing drugs that include the likes of omeprazole and lansoprazole.

听

It seems our advice that you need to come off them slowly, and take other antacids, to avoid worsening of your indigestion as acid levels bounce back after being suppressed for so long, struck something of a chord.

听

Patricia e-mailed to say that she鈥檚 been taking PPIs for two years, but has recently tried gradual withdrawal and is now eight days clear and feeling much better.

听

Well I鈥檝e been on them for a similar period to you Patricia and I鈥檓 at the same stage of weaning coincidentally, I am getting by with the help of chewable antacids and getting through them but I suspect it鈥檒l be a few weeks before I know if I鈥檒l ever be able to manage without them completely.听 Still, if you don鈥檛 try鈥�.

听

Derek Gott e-mailed to ask if there are alternatives that are less likely to cause problems on withdrawal.听 Well yes there are Derek, but they tend not to be so effective which is why PPIs are so widely used. One to discuss with your own GP if you fancy trying an older alternative which might be easier to stop.

听

If all this is news to you then you can listen again via the Inside Health page of the Radio 4 website.

听

Now, how assertive are you with your doctor? Because it pays to be assertive according to reports in the news at the weekend with headlines like 鈥淏e pushy with your GP to get best drugs鈥�.

听

Well the man behind those headlines is Professor David Haslam, Chair of the National Institute of Health and Care Excellence, and he joins me now. David, were you happy with the way the story was covered?

听

Haslam

Apart from the headline no, the headline which suggests people should be pushy was not a word I would ever use.听 But certainly encouraging people to take a real interest in their own treatments is incredibly important and also recognising the fact that some of the NICE approved medications just aren鈥檛 being used where they should be.

听

Porter

Well the term I used there was assertive, would you be happy with assertive?

听

Haslam

Well it鈥檚 not a question of being assertive or passive or anything, it鈥檚 recognising that medicine isn鈥檛 something that should be done to people, it鈥檚 something that should be done with people.听 Doctors and patients working together.

听

Porter

Can you give me an example where you think patients might be missing out?

听

Haslam

Well we鈥檝e got evidence from a couple of areas.听 First of all the Health and Social Care Information Centre which collects statistics on the use of different treatments has shown that, for instance, a drug called Sunitinib, which is used for renal cancer, or another drug called ranibizumab, which is used for macular degeneration, are not being used as much as we might expect, certainly in some areas of the country.听 But we found that things like the new use of new anticoagulants for people with atrial fibrillation, which is a very common condition鈥�

听

Porter

So these are alternatives to warfarin that people might have heard of?

听

Haslam

Very much so and they鈥檙e just not being taken up to the extent that we might have expected.听 And so what I鈥檓 keen to do is that patients should be part of that discussion.

听

Porter

Of course you don鈥檛 know whether that鈥檚 because doctors aren鈥檛 keen on them or whether patients aren鈥檛 asking for them do you?

听

Haslam

Well that鈥檚 why we鈥檙e doing work into trying to found out why that is very much.听 I suspect it鈥檚 a mix of education, it鈥檚 a mix of knowledge, I mean NICE puts out a lot of stuff so maybe folks don鈥檛 know about it.听 But I think it鈥檚 important patients understand what their rights are as well.

听

Porter

Well Margaret McCartney鈥檚 listening in our Glasgow studio.听 Margaret, I mean using this word assertive is there anything wrong with a patient being assertive?

听

McCartney

There鈥檚 certainly nothing wrong with patients who want to get involved with making lots of decisions about their healthcare and in fact that鈥檚 the way I work every day 鈥� we want to sit down and have a conversation between patients and doctors deciding what would be the most appropriate treatments, what would be the preferences, what are the things we鈥檇 like to avoid.听 I suppose my concern is that when we鈥檙e talking about assertiveness it kind of sounds as though doctors and patients have been placed on opposite sides and that one party wants something that the other person doesn鈥檛 want to give and that鈥檚 really not what I went into medicine to do and it鈥檚 certainly not the kind of relationship that I aim to have with patients.听 I see myself as being on the same side, trying to work out what the best thing to do is.

听

Porter

It鈥檚 oft said in the NHS, a much abused clich茅, that the squeaky wheel gets the grease and I suppose my concern with this is that we have patients who are well informed who are well educated who are able to stand on their own two feet and say look I know, I read this in the newspaper, I heard it on Inside Health, therefore I would like you to look into it for me doctor.听 But they鈥檙e often not the most vulnerable patients are they?

听

Haslam

No of course not and no I鈥檓 really wary of what鈥檚 called the inverse care law where people who need the most get the least.听 And so鈥�

听

Porter

And vice versa.

听

Haslam

And vice versa, very much vice versa.听 But that isn鈥檛 to say that I don鈥檛 want patients to be really involved and engaged.听 And as the three of us know I mean good GPs and good doctors of every sort will explore the patient鈥檚 ideas and fears and expectations and if you haven鈥檛 found those out it鈥檚 going to be really difficult to provide good care.

听

Porter

Margaret, for me the headlines made it feel like unless you were pushy, unless you challenge your GP, you鈥檙e going to get second rate treatment, is that how you felt?

听

McCartney

Yeah, that is how I felt and I think that鈥檚 absolutely catastrophic because what it鈥檚 really saying is it鈥檚 survival of the fittest, unless you can read the guidelines, unless you鈥檝e got access to the internet, unless you can understand them, unless you鈥檝e got a family member that can push for something for you you鈥檙e basically going to be left to rot.听 That鈥檚 the feeling I had.听 And if we do anything in the NHS it鈥檚 to treat our patients equally, it鈥檚 about who needs what and making sure that they get what they need.听 And it鈥檚 not about getting what you want, it鈥檚 about getting what you need and what鈥檚 appropriate for you.听 Professor Haslam talked about the American attitude of being more assertive and more demanding, in fact America is at a crisis with its healthcare, they鈥檙e spending far too much money on stuff that people just don鈥檛 need, won鈥檛 benefit from and can only benefit the medical industry as it were.听 When you actually want to talk about who gets the care that they actually need as opposed to what they want we really have to look to our service, the NHS, and the way that we try and appropriate treatments to people who are most going to benefit from them.

听

Haslam

I share your concern about the headlines but what I was talking about with 鈥� I used to have quite a few American patients, as well as British patients, in my time working as a GP and I found with the average American patient if I said I鈥檓 recommending this medication they鈥檇 say tell me about it.听 And the average British patient 鈥� and this is quite a while ago 鈥� would say thank you doctor.听 Now I think it鈥檚 actually really quite important 鈥� I mean every doctor, I鈥檓 sure the three of us, are very aware of large numbers of patients, maybe not listeners to Inside Health, but large numbers of patients who if you asked them what pills they鈥檙e on they say oh I don鈥檛 really know, I鈥檓 on the white pills.

听

McCartney

But the idea that that could be somehow reversed by everybody taking more of an interest I think is, to be honest with you, not terribly realistic.听 People who are on a lot of medication that they don鈥檛 understand why they鈥檙e taking it or what for for lots and lots of very complex and difficult reasons and I think to sort of say just take a bit more of an interest in what the doctor鈥檚 giving you is only going a tiny percentage of the way 鈥� we live in an unequal society, we live in an era where health literacy is not great for a large amount of the population, just getting a bit more in your 10 minutes with your GP is not really the answer.

听

Haslam

No but I suspect it鈥檚 not going to do a huge amount of harm either.听 I mean it鈥檚 just 鈥� you鈥檙e absolutely right 鈥� it鈥檚 one step, one part of a really complex agenda.听 But I think 鈥� it just feels to me that the NHS has had this tendency to be very paternalistic about healthcare and the more we can work in an equal and sharing way, recognising that there are a great swathes of society for whom that鈥檚 a challenge and doctors need to address that, then I think the better.

听

Porter

Professor David Haslam, Chair of NICE, Margaret McCartney our resident sceptic, we must leave it there. 听Thank you both very much.

听

Now let鈥檚 continue with the NICE theme with a look at its latest guidance on the diagnosis and management of prostate cancer published earlier this month.听 The striking change for us here at Inside Health was the inclusion of MRI scans.听 Put simply the updated guidance confirms the role of MRI in helping doctors decide how to investigate suspected cancers. Not all will need treatment, but sorting the aggressive cancers that do, from the slow growing variety that do not, can be difficult.

听

So how do MRIS scans improve on current tests? 听Well to find out I went along to University College Hospital to meet consultant urologist Professor Mark Emberton.

听

Emberton

It鈥檚 really quite shocking how bad our tests are.听 We鈥檝e had a finger, which isn鈥檛 particularly sensitive at detecting鈥�

听

Porter

To feel the gland.

听

Emberton

Exactly right.听 Then PSA came along about 20 years, and that does identify people at increased risk of prostate cancer鈥�

听

Porter

This is the blood test yeah.

听

Emberton

Correct.听 And then to actually identify prostate cancer we put needles into the prostate and that鈥檚 a process that is random.听 So it鈥檚 the only cancer in which we do that, all other cancers 鈥� and if you have a biopsy for a breast cancer, for instance, you either have a lump or the mammography, the scan that tells you where to put the needle, same goes for liver, kidney, there鈥檚 no other cancer in which we blindly put needles into the prostate.听 So increasingly we鈥檙e finding out that our needles never really went to the right place and there are parts of the prostate 鈥� the apex, which is the bow of the ship, the middle bit and the bit that鈥檚 furthest away from the rectum 鈥� never gets sampled.听 So quite often we tell me they鈥檙e all clear when in fact they鈥檙e not.

听

Porter

So this might be a man who鈥檚 got a raised PSA test, goes in, has a biopsy, and we can鈥檛 find anything?

听

Emberton

Exactly.听 And it鈥檚 a nice consultation because the patient鈥檚 delighted but the urologist deep down knows that the certainty of that reassurance is to be guarded.听 And a recent trial published this month looked at patients that had two negative biopsies and then had a very, very detailed biopsy 鈥� so these are men that were told twice that they were clear 鈥� 58% of them were found to have clinically significant disease when they had this very special biopsy鈥�

听

Porter

More than half.

听

Emberton

Absolutely鈥� that we call prostate mapping.

听

Porter

So what the NICE guidance is suggesting now is that if you have a negative biopsy that the next stage 鈥� rather than be reassured and said you can go everything鈥檚 fine 鈥� the next stage would be an MRI scan and perhaps another biopsy?

听

Emberton

Correct.

听

Porter

So this is the first time that MRI scans have featured in the NICE guidance, what鈥檚 their role?

听

Emberton

It does two things.听 It tells us where a tumour is within the prostate, so will allow us to guide our needles to it and therefore if the patient tests negative we can have greater reassurance.听 It also allows our needle to get a bull鈥檚 eye, if you like, and so that the information that we convey to patients is more representative.听 In the past we missed it we didn鈥檛 know and if we got a glancing blow we didn鈥檛 know.

听

Porter

Professor Emberton works closely with consultant radiologist Dr Claire Allen, whose job it is to interpret the MRI results and that can be tricky.

听

Allen

Everybody鈥檚 prostate is different and they鈥檙e like fingerprints and that鈥檚 where the real technique of identifying tumour and skill, hopefully, comes in because everybody鈥檚 prostate is different.

听

Porter

Because your job is to differentiate between what鈥檚 normal and what鈥檚 abnormal.

听

Allen

And that鈥檚 鈥� and it鈥檚 relatively straightforward if you鈥檙e looking at structure that should look the same in everybody but in the prostate they all look completely different.听 This is a patient who is in his 70s and in young men you only have this outer casing.听 If you consider a cauliflower and this outer bit, which we call the peripheral zones, is like the green leaf of the cauliflower and that is the bit that you have and that you鈥檙e born with and that younger men you鈥檒l only see that bit of the prostate.听 This whole central area here, it鈥檚 called the transition zone, and that鈥檚 the bit that grows throughout a man鈥檚 life and that will grow to a different extent in different men.听 We used to think with tumours that the majority of tumours used to only occur in this part, the outer, sort of the green leaf bit of the prostate, but we now are increasingly aware that there are more and more tumours found in this central transition zone.听 And the reason for that is that we never used to biopsy this bit and it was systematically an area of the prostate that got missed when men were biopsied.听 And it鈥檚 the ability to use these new techniques which really have only been available for maybe the last five to six years that has really pushed on our ability to identify prostate tumours.

听

Porter

Can you show me one where there is something that you鈥檙e concerned about?

听

Allen

So you recognise what we were just looking at as a normal prostate and you can see in this particular patient he鈥檚 got a different sized gland, it鈥檚 overall a little bit smaller, and you can see his prostate here, you can see the outer wrapping, if you like, that is still quite uniformly white but you can also appreciate that coming out of the upper surface of the prostate is a big irregular mass, which was not present on the previous scan, you can also see that it looks black on the scan and this is tumour and this is a very typical appearance of tumour.听 This is the sort of tumour that maybe 10 years ago we would never have found because you can鈥檛 feel it when a doctor puts a finger into the back passage, this tumour would not be palpable鈥�

听

Porter

Because it鈥檚 at the front of the gland.

听

Allen

Because it鈥檚 at the front of the gland.听 And also if you put a biopsy through the back passage it is well away from the biopsy track.听 So these are the sort of tumours which we never found.

听

Porter

Okay, I鈥檓 sitting here as a pragmatist and I鈥檓 thinking why aren鈥檛 you doing the MRI scan first and then the biopsy?

听

Emberton

A great question.听 That is my own disappointment but I think there may be good reasons why.听 So I do it, if I was having a biopsy I would ask for an MRI beforehand, on a straw poll of urologists in a recent conference all the urologist said they鈥檇 do it.听 And I think to derive location you have to do an MRI beforehand, if you鈥檙e going to do a targeted biopsy you need to do your MRI before.听 The other things that MRI do, which is reassure men that they don鈥檛 need a biopsy, so in other words if a woman has a mammogram and it鈥檚 negative she doesn鈥檛 have a biopsy, if you have a CT scan of the kidney and it鈥檚 normal you don鈥檛 have a biopsy.听 That is the subject of a very important trial which is currently recruiting.听 So if I were to have a PSA of six, which is abnormal, an MRI which was deemed to be normal by a very good radiologist, how sure can I be that I am free of clinically significant disease?听 And that鈥檚 being evaluated currently in a trial called PROMIS and the beauty about that trial is that it鈥檚 opening out throughout the country, so that if men today are offered a biopsy or feel they need one they can access that trial and get a very high quality MRI and a verification biopsy in the same sitting.

听

Porter

MRI obviously has a role in getting the diagnosis correct in the first place but what about in this other area that鈥檚 very important too 鈥� is looking at what to do with somebody once you鈥檝e diagnosed them?听 A lot of people listening will think I鈥檝e got a prostate cancer, I don鈥檛 really care whether it鈥檚 a quiet one or an aggressive one I just want it out, please treat me so I don鈥檛 have to worry about it 鈥� what鈥檚 the downside of over treatment?

听

Emberton

So you鈥檝e mentioned over treatment, which is a very interesting concept but a difficult one to grasp.听 It鈥檚 the consequence of over-diagnosis.听 And so this is about treating people who if left untreated would suffer no reduction in quality of life or quantity of life.听 And if you catch a cancer very, very early it鈥檚 a bit like doing a weather report a month in advance, you can鈥檛 really predict very much.听 And so many cancers are just not destined to progress in that way, particularly the prostate.听 So probably the biggest error we commit today is to treat people unnecessarily.听 The downsides that bother patients are really aspects of their genitourinary function, this is about their ability to get and maintain erections, their ability to ejaculate and also their ability to pass urine normally and incontinence, particularly when they cough or sneeze.听 With radiotherapy the issue of incontinence is less but there is effects on the rectum and also the bladder than can lead to sometimes faecal incontinence and sometimes an overactive or a small bladder.听 The other error we make is under-diagnosis and under-treatment and these are men that are told they鈥檙e all clear when in fact they鈥檙e not.听 And just the other day in clinic I saw a man who鈥檇 have five previous biopsies, all negative, and the PSA was rising over the preceding six to eight years, he was probably curable six to eight years ago, he was definitely incurable when I showed him his large tumour in the anterior part of the prostate.
