Online GP consultations, Pre-eclampsia and could aspirin treat cancer?

Dr Mark Porter investigates the digitisation of the NHS: are online GP consultations the future? A new test for pre-eclampsia and could aspirin help in the treatment of cancer?

Dr Mark Porter investigates the digitisation of the NHS: are online, asynchronous GP consultations the future? He visits a GP surgery in Tower Hamlets to find out how patients are getting in touch online, in their own time. Does it help improve access for patients and manage workload for busy GPs?

Manu Vatish, an obstetrician from the University of Oxford, explains that currently every pregnant woman will be tested for pre eclampsia and how a new test could help accurately identify the 4% of women who actually get the condition.

And could aspirin help in the treatment of cancer? Mark talks to Professor Peter Elwood from Cardiff University about his recent study into the evidence and to Professor Janusz Jankowski, a gastroenterologist at Morecambe Bay hospital to talk about the implications and risk and benefits.

Porter

Hello.听 Coming up in the next half hour:听 Yet another use for aspirin, I interview the researcher behind a new study that suggests it could treat cancer.听 And preeclampsia 鈥 if you鈥檝e ever had a baby you will have been screened for the condition but how much do you actually know about it?

Clip - Vatish

So, when my wife was pregnant, and she鈥檚 married to an obstetrician, she said 鈥 What鈥檚 this preeclampsia thing.听 And I sat there and I thought 鈥 well, if she doesn鈥檛 know, then what hope is there for anybody else.

Porter

Morea about preeclampsia later.

But first, the digitisation of the NHS which will, among other things, transform the way that patients interact with their GP.听 Being able to Skype your doctor from your phone or computer seems to be the most widely promoted example of the sort of change we can all expect.听 But do video consultations live up to the hype?

Dr Margaret McCartney is in our Glasgow studio.听 Margaret, how much research has been done in this area?

McCartney

Well not nearly enough.听 There certainly has been some research done over the last few years looking at the pros and the cons of video consultation and I think it鈥檚 fair to say that there are more questions than answers at the moment.听

Porter

What sort of cons are there?

McCartney

Well there鈥檚 lots.听 So, the advantages that seem to be touted are things like more efficient, more accurate, allows doctors to spread their workload more evenly, it might allow patients to keep continuity of care with doctors, less travel time, don鈥檛 have to get in quite so often.听 That鈥檚 the kind of things people are saying.听 There鈥檚 a really great study that was published in the journal of Medical and Internet Research in 2018 and they looked at the roll out of three clinics trying to do more video consultations and they found in antenatal care they just couldn鈥檛 roll it out at all, it was just too difficult to do, it wasn鈥檛 popular with their patients or with their doctors.听 And they found huge problems, actually, in just rolling out the technology itself and they really found that doctors were having to sort of fix technological difficulties that really hadn鈥檛 been properly funded or accounted for.

Porter

So, would it be fair to say, that the research doesn鈥檛 back what we鈥檙e hearing in the media about this as being this new revolution that鈥檚 going to impact on the NHS?

McCartney

The research definitely does not back the idea that this is going to be something huge and new, that鈥檚 actually going to work for people.听 Now it might work for some people, some of the time, we shouldn鈥檛 write it off but I think we should be very careful of making big claims that simply can鈥檛 be held up with the evidence for it.听 But I think the problem that we have is that it鈥檚 being hyped beyond all reason just now and unless we鈥檙e really careful and look at the pros and the cons we鈥檙e in danger of doing of far more harm than good.

Porter

Thank you, Margaret.听

Well video consultations may be grabbing the headlines but a growing number of GP surgeries are opting for another way to boost their offering 鈥 online consultations that enable patients to send in their query or concern on any day at any time and their GP will get back to them typically the same or next day with an answer.听 Which may be anything from a prescription or booking a test to an appointment for a telephone or face-to-face consultation.听 Well over a thousand practices already offer online consultations and their ranks are swelling by the day.

Around 20 companies offer different IT packages but eConsult is one that鈥檚 widely used.听 London GP Murray Ellender helped found it.

Ellender

Like all GPs we were really struggling with demand and the need to manage lots and lots of patients coming through the door and we knew that there was some solution in digital and wanted to explore different ways of patients interacting with us.听 And we looked at various options.听 So, we looked at things like video, as a way to consult but actually video works for some patients but doesn鈥檛 save a lot of time, still need 10 minutes of a doctor, 10 minutes of a patient.听 So, we came up with a different idea, which is gather the history in the patient鈥檚 time, push it through to the practice, through to the GP who knows the patient has the record and then let the GP make the decision about what to do.

Porter

So, what does this allow patients to do now, if their practice is using it, that they couldn鈥檛 have done before?

Ellender

So, I guess it allows them to contact their GP any time day or night.听 And it gives patients access to their own GP when they need it.听 So, I think because of the increasing demands we now have a system where patients have to battle through on the phone at 8 o鈥檆lock in the morning in order to secure a face-to-face appointment.听 Whereas we know that actually not everything has to be handled with a face-to-face appointment, there鈥檚 a lot that comes in to general practice, into the consulting room, that could be handled without you necessarily having to come in.听 So, if we can gather that information up and push it through to the GP, the GP can then make a decision about what to do.

Actuality 鈥 phone ringing

Hello, St Stephen鈥檚 Health Centre, can I help you?

Kullar

My name is Balvinder, Practice Manager at St Stephens.听 The complaints and grumbles we were getting were generally around our telephone system and we employed more receptionists and all that seemed to do was drive up demand.

Porter

So, what sort of grumbles were you getting?

Kullar

That the phone wasn鈥檛 answered quickly enough, you know if a receptionist is triaging a patient and trying to get some basic clinical information that takes some time.

Porter

People got fed up with being on hold.

Kullar

Yeah, people want immediate access, they don鈥檛 want to be kept holding and listening to music.

Porter

So, you knew you had to do something.

Kullar

We had to try something different to improve patient access.

Bower

My name is Rachel Bower, I鈥檓 a GP partner here, have been since 2004.听 As for many GP surgeries we have not as many GPs as we would like.听 We face a recruitment and retention crisis.听 Difficult to recruit salaried GPs in particular, so we鈥檙e probably about down by 25% on the amount of GP capacity we would like.

Porter

So, in practice that means it鈥檚 difficult to get in to see a doctor and when you do there are long waits?

Bower

Yes, I mean we do make sure that we are able to offer emergency appointments when clinically necessary but we鈥檙e still sometimes struggling with on-the-day demand.

Porter

St Stephens Health Centre in Tower Hamlets, East London, is a typical busy inner-city practice, it鈥檚 been using online consultations since 2013, so how does their current system work?

Ellender

The route in for patients is via the practice website.听 Most practice websites tend to be picture of the practice and a phone number.

Porter

We鈥檝e got a typical one here on your laptop.听 So, like many practices, my practice website has a picture of the surgery with a telephone number and other links, all very useful of course.

Ellender

So, what we do with practices is say look make the offer to consult-online really prominent, so here鈥檚 the one for St Stephen鈥檚 Health Centre. And you can see it鈥檚 got the NHS logo, it tells you you鈥檙e still on the practice website but actually very prominently it says contact our doctors online.

Porter

So, you鈥檝e got three big orange blocks here, explain what they are.

Ellender

So, here we give patients the option to 鈥 they may need help for a specific condition, so I know I鈥檝e got back pain or I think I may have a urinary tract infection.听 But we鈥檝e got another one for actually I鈥檝e got a series of symptoms, I鈥檓 not quite sure what鈥檚 wrong.听 And we鈥檝e also got a section for administrative queries, so I need a letter or I need a repeat of a fit note, that kind of thing.

Porter

Going back to your back pain example, I鈥檝e got back pain and I鈥檝e clicked on this thing here, then what happens, take me through the journey, what we expect to happen to the typical patient?

Ellender

Sure, so the next bit of the journey, the patient will, if they鈥檝e got back pain, we鈥檒l offer them the ability to kind of interact with self-help advice or we can signpost into other services.听 Or if they think they need a GP we鈥檒l then take a history from them about their back pain.

Porter

And this can be done on a Sunday morning, so they鈥檙e at home, they鈥檙e not queuing on the phone.

Ellender

Absolutely, they can access this any time.听 But we鈥檙e asking them a history about their back pain, much in the same way that I would ask or you would ask a history if you were sat in front of them.听 So, it鈥檚 a kind of structured history for back pain, within it are red flags for safety 鈥 so that actually if there鈥檚 a more urgent symptom it鈥檒l pick that up and maybe route them somewhere else.听 But ultimately, what we鈥檙e trying to do is gather a structured history from the patient about their back pain that we then push through to the practice and then when the practice opens they鈥檒l pick that up and present it to the doctor who鈥檒l make a decision about what to do with that patient.

Bower

One of the advantages over the traditional consultation is that they can say up front and it gives them a chance to express themselves in their own time and in the convenience of their own home what it is that they鈥檙e after, what their expectation is.听 Surprisingly, even for mental health problems, this can work quite well.听 So, they can go into some detail of how they鈥檙e feeling and whether they would have a preference for talking therapy or medication, for instance.听 Another example might be, I鈥檓 wondering if I鈥檓 anaemic, I鈥檝e got a history of previous anaemia.听 The advantage of receiving that as an eConsult is that you can streamline it a bit and prioritise it a bit and maybe arrange for them to get a blood test before they come to see you.

Porter

And in terms of your workload here, have you, as a stressed GP, found it helpful, have you noticed a difference?

Bower

It鈥檚 difficult to know exactly where to put it in the working day and one wouldn鈥檛 want to necessarily over-prioritise these cases simply because it鈥檚 a new development and we want it to work.听 So, the timeline of it is we鈥檙e supposed to get back to them by the end of the next working day.

Porter

When do you actually do this, I mean how do you fit it in?

Bower

Well currently, it鈥檚 the on-call GP and I would tend to do it in the evening.听 I might have completed seeing my last emergency patient at that point and maybe done a home visit.

Porter

It sounds to me like you鈥檙e 鈥 you like the system but you鈥檙e actually having to work quite hard at it.听 Do you think it鈥檚 time and resource saving for the practice or is it a quality issue for the service that you鈥檙e providing?

Bower

It鈥檚 a bit of both of those.听 I really like the fact that it smooths out the on-the-day demand.听 You鈥檝e got not people crying for appointments on the day or unhappy 鈥 I鈥檝e had to wait weeks and weeks to see you.听 You鈥檝e established they need to be seen and you鈥檙e establishing a slightly better timeframe within which to do that.

Ellender

Patient feedback is overwhelmingly positive.听 With the kind of conditions they鈥檙e consulting for they like the fact that they could spend some time answering questions in their time, they weren鈥檛 time pressured and they may then get a prescription issued or some advice issued without them having to take time off work or time out of a busy life looking after kids etc., to come into the surgery.听 So, actually patients 鈥 patients really welcome this.

Porter

And Murray, have you noticed any trends in terms of the sort of conditions that people are enquiring about?听 Is it different on the system than it would be in face-to-face surgery?

Ellender

One of the things we certainly find is that patients feel a lot more comfortable consulting this way for certain conditions.听 So, conditions that patients may perceive as embarrassing, things like rectal bleeding or sexual health problems or even mental health, we get a high proportion of patients who come through with anxiety depression because actually they find it a lot easier to express their symptoms and talk about their condition like this, so we鈥檙e actually picking up conditions earlier, they鈥檙e presenting earlier, than actually making an appointment and overcoming that barrier of going in physically to see a doctor and pick something up.听 So, actually that鈥檚 a really interesting facet of this.

Porter

However, a concern shared by sceptics is that introducing another gateway into the practice simply encourages more contacts and more work.听 St Stephen鈥檚 Practice Manager, Balvinder Kullar.

Kullar

What we鈥檝e seen with the data is that just for December, for example, December 2018 we had 1250 patients contact us via eConsult, out of those 1250 contacts 280 were actually transformed into an eConsult that was delivered to the practice.听 So, eConsult effectively triaged out approximately a thousand of those contacts by diverting them off to other services.听 We鈥檙e not just recycling these patients, they鈥檙e not then coming through another route.听 So, hopefully it鈥檚 stabilising our patient demand.

Ellender

We know from working with lots of practices now you can close about 70% of those consultations down without calling the patient in.听 So, either with sending them a prescription to the pharmacy and a message to the patient saying go to the pharmacy or you might call them back just to clarify something on the phone but in about 30% you do have to bring in for a face-to-face but you can then triage them according to urgency.

Porter

Who is using it nationally, do you have a profile of the typical user?

Ellender

The biggest age group cohort of users are between the age of 40 and 60.听 Although we鈥檝e got significant numbers over the age of 65, we鈥檝e even had three users over the age of 100.听 So, catering to the people who use general practice, don鈥檛 assume just because it鈥檚 digital it鈥檚 the young fit 20-40-year olds because the reality is those people aren鈥檛 big users of general practice.

Porter

Murray Ellender.听 More details, as ever on the Inside Health page of the Radio 4 website.听听 And because online consultation is being adopted so rapidly in primary care, we鈥檒l be keeping a close eye on developments and ongoing research into its impact.

Now, every year in the UK, at least three-quarters of a million pregnant women will be screened at their antenatal appointments for preeclampsia, a potentially lethal complication of pregnancy.听 Tell-tale clues include high blood pressure, fluid retention and protein in the urine.听 But how much do women and their partners actually know about the condition?

Dr Manu Vatish from the University of Oxford is part of a team that鈥檚 developed a new test, to help manage women at risk.听 Yet even his family were not as clued up as you might expect.

Vatish

So, when my wife was pregnant, and she鈥檚 married to an obstetrician, she said 鈥 What鈥檚 this preeclampsia thing?听 And I sat there and I thought 鈥 Well, if she doesn鈥檛 know, then what hope is there for anybody else?

Porter

What does it actually mean?

Vatish

Well, eclampsia comes from the Greek, meaning lights or sudden flashing of lights and preeclampsia means before that.听 And I think the historical reference tells you how long this disease has been in our consciousness, that we鈥檙e using an ancient Greek word for a disease that still kills a woman every seven minutes on the planet.

Porter

The eclampsia effectively is epileptic type seizures.

Vatish

So, the way the disease works is we know this is a disease caused by the placenta or the afterbirth and we know that sometimes that placenta doesn鈥檛 work properly and that happens in the early part of pregnancy and then as you move towards the later part you start to get some symptoms and signs that every pregnant woman goes 鈥 why are they dipping my urine, why are they measuring my blood pressure.听 And we鈥檙e looking for high blood pressure, protein in the urine and we鈥檙e asking them about certain symptoms and signs that might tell us that eclampsia鈥檚 about to happen.

Porter

So, we鈥檙e looking for preeclampsia and if we miss it or even if we pick it up sometimes the woman might, rarely in the UK fortunately, progress on to eclampsia.

Vatish

Yes.听 So, seizures which generally can last several minutes, they represent a fairly impressive threat to the mother鈥檚 life and to the baby鈥檚 life.听 And so, we鈥檝e got lots of remedies to try and reduce that fitting but our goal is to try and identify that woman before she ever gets there.

Porter

Because if we don鈥檛 pick up preeclampsia, it can lead to seizures and death for the mum.听 What are the implications for baby?

Vatish

It means the baby鈥檚 much smaller than it should be, so it suffers something called intra-uterine growth restriction, which is smaller than it should have been.听 And the other things that can happen to the baby are it鈥檚 often delivered early, is a premature delivery, and the complications of that and occasionally the placenta can actually shear off because the blood pressure鈥檚 so high and we call that an abruption and that鈥檚 obviously a fairly significant and serious event for the baby.

Porter

And how big a problem is it?听 I mean every woman is screened for it, how many actually develop some degree of problem with preeclampsia?

Vatish

In the UK it鈥檚 around about 3%.听 But the problem is we don鈥檛 know which 3%, so we have to screen 100% to find 3%.

Actuality

Now have you brushed your teeth yet Merlin?

Yes.

Are you going to put a sticker on your top to show that you have?听 Good boy.

Bagga

My name鈥檚 Ushi Bagga, I鈥檝e got two children and I had preeclampsia in both of my pregnancies.听 It was all a really big shock.听 Around kind of 32, 33 weeks I started getting quite a lot of swelling in my feet, in my ankles and at the time I just thought that it was probably part of a normal pregnancy symptom 鈥 I knew other people that had it and kind of people were just going oh yeah, I remember that.听 So, I didn鈥檛 really think very much of it.听 And I was going to all my regular antenatal appointments.听 Every time I went I鈥檇 be asked to do a urine test but I really had absolutely no idea what the test was for.听

And then it was when I was 35 weeks and I had a midwife appointment on my way to work, so I just sort of popped in.听 And the midwife took my blood pressure and she was kind of chatting to me and asking how I was.听 And I happened to mention that I had a headache and also that I thought that I might need to get my eyes checked, so maybe get new contact lenses because my vision wasn鈥檛 as clear as it had been.听 And as soon as I said that, I knew that I鈥檇 said something out of the ordinary because the midwife鈥檚 face completely changed, she retook my blood pressure.听 She explained that she wanted me to be admitted to the antenatal ward at St Thomas鈥 to do some further tests and also to be monitored.听 And at that point she mentioned preeclampsia.

Vatish

Certainly, being in your first pregnancy is a major risk factor.听 There鈥檚 a genetic input, there鈥檚 an immune input.听 If you change partners and therefore you鈥檝e got a new immune environment, that鈥檚 also a risk factor, equivalent essentially to being in your first pregnancy, even though you鈥檝e been pregnant before.

Porter

Because the baby鈥檚 genetically different to you, so it presents a challenge to your own immune system.

Vatish

Yes.

Porter

But what鈥檚 actually going wrong?听 I mean when I was training my professor was quite an old chap and he used to refer to toxaemia of pregnancy, as if there was some toxin released into the system.

Vatish

So, in some ways your professor was using quite arcane terminology.听 But in some ways, he鈥檚 actually still quite right.听 So, the disease is really a disease of your vasculature, your blood vessels, not working properly and the abnormality of those blood vessels results in the high blood pressure and it results in the protein in urine and all the other symptoms and signs that we look for.听 One of the things that toxaemia defined was poison, I mean I suppose the word itself is toxic and it turns out that actually you鈥檝e got a change in the balance of factors that are released.听 So, two markers that are known to be released by the placenta are involved in blood vessel growth.听 One of which is, helping blood vessels to grow, the other one is stopping blood vessels to grow.听 And what we see in women with preeclampsia there鈥檚 more of the molecules that are stopping blood vessels from growing.听 And Oxford became the first hospital in the UK to be using that as a diagnostic test, it鈥檚 a slightly more accurate way than screening people鈥檚 blood pressure or urine because your blood pressure can be up for many reasons and you can have protein in your urine for many reasons.听 And so, the biomarker鈥檚 a bit more specific.听 And the way that test works is that if the test is negative it tells us really strongly that the woman hasn鈥檛 got preeclampsia when we see her and also is unlikely to get preeclampsia for the following seven days.

Porter

And that鈥檚 important because it affects the management of these women?

Vatish

If we tell somebody that they鈥檝e got preeclampsia or we鈥檙e admitting them because we suspect they have preeclampsia there鈥檚 anecdotal evidence from around the UK and many colleagues around the world that women are delivered because of the genuine belief that they鈥檝e got preeclampsia.听 That鈥檚 committed the woman to an operative delivery and it鈥檚 delivered them of a pre-term baby.听 It then subsequently becomes apparent that the woman didn鈥檛 have preeclampsia and actually had another condition that was very similar.听 Anything that can help us to improve our diagnostic ability can only be a good thing.听 And I will say that in Oxford we are currently undertaking a trial to deplete the circulation of these toxins.

Porter

Which involves taking blood from the mother and (in inverted commas) 鈥渃leaning鈥 it but what are we taking out then?

Vatish

It鈥檚 a protein, the markers that I told you about that we鈥檙e using as diagnostics, one of which is vastly elevated in women with preeclampsia, we called it Soluble Flt-1 and the filter we have specifically removes that Soluble Flt-1.

Porter

So, you take their blood, filter it and give it back to them, effectively?

Vatish

Yes.听 We鈥檝e just done our first patient and extended her pregnancy by several weeks.

Porter

Obviously, the aim of the antenatal care is to spot women who are at risk.听 What happens when you identify someone who鈥檚 got preeclampsia, how do we treat them?

Vatish

Well for the last 2,000 years the treatment has been pretty standard, which is you watch the woman until you鈥檙e unable to be sure that she鈥檚 still safe and then you deliver her.

Bagga

The consultant said that because of the preeclampsia I鈥檇 have to stay in hospital until about 38 weeks when they鈥檇 try and induce.听 I think the thing that I found hardest was that physically I felt absolutely fine, I didn鈥檛 feel ill at all but I was being told that I had this life-threatening condition.听 I was admitted on the Monday and on the Friday my waters broke, quite suddenly in the middle of the night, her heartbeat was showing that she was getting distressed, so, at that point they decided to do an emergency caesarean.听 She was four weeks early, four pounds 10 ounces, so she was quite small.

Porter

All the best things come in small packages.听 Ushi Bagga.听 And there鈥檚 a link to the test that Manu Vatish mentioned and more information on preeclampsia on our website.

Aspirin may be over a hundred years old but it鈥檚 still full of surprises.听 And the latest one is that it may have a role in the treatment of cancer.听 We鈥檝e known for some time that aspirin can reduce the likelihood of developing some forms of cancer but now new research has highlighted a possible role in people who already have the disease.

Professor Peter Elwood from Cardiff University led the study.

Elwood

We put together all the published evidence on aspirin taken by people with cancer.听 We did a very extensive and careful literature search, we found 71 papers which reported aspirin taking in a wide variety of cancers.听 We found reduction in cancer mortality and a reduction in the spread of the cancer within the body.听 The reduction in mortality was around 20%, which means that at any time after diagnosis there will be 20% more people who are taking aspirin alive than people who are not taking aspirin.听 That鈥檚 a pretty astounding result.

Porter

That is remarkable.听 Do we know how the aspirin might be working?

Elwood

The mechanisms in reducing the spread of cancer within the body have been very well worked out and those mechanisms are dependent, largely, on blood platelets, through a reduction in platelets鈥 stickiness.

Porter

So, aspirin reduces platelet stickiness, which in turn reduces the likelihood of spread?

Elwood

That鈥檚 right.听 But the effect on the original cancer, itself, are complex, there are effects on the growth of the cancer, on the vascularisation 鈥 the development of new blood vessels enabling the cancer to grow 鈥 there are these mechanisms but obviously there are probably a whole lot of effects of aspirin on mechanisms to do with cancer growth.

Porter

Aspirin鈥檚 long been perceived as a double-edged sword, in that there鈥檚 often a price to pay in terms of side effects for any benefit, what were the downsides identified in your review?

Elwood

I was disappointed at the way that the media tended to focus on the risks of aspirin.听 Now we do not minimise, we do not dismiss the risks of aspirin, but when a patient has been given a diagnosis of cancer the outcome is depressing indeed and the risk of a bleed, which we had already shown is most unlikely to be fatal, is trivial and yet the media, across the world, seem to focus on the risks rather than the benefit.

Porter

Peter, if this was a brand-new drug for cancer that reduced mortality by 20% it would be all over the news.

Elwood

Exactly, it would get headlines and it would be on the 成人论坛 daily news, yes.

Porter

What sort of cancers did you look at?听 Was it just the common forms?

Elwood

We searched the literature and there got all of cancers.听 The main cancer, of course the most common cancer, is bowel cancer and following that breast cancer and prostate.听 So, our analysis focused on those three common cancers but our main results are based on all the 71 reports of different cancers, studied by different teams across the world, over the last 30 years.

Porter

Professor Janusz Jankowski is consultant gastroenterologist at Morecombe Bay University Hospital and has a special interest in aspirin and cancer.

Jankowski

This really was a unique study showing potential benefit with very little disadvantage in people with advanced disease.听 We鈥檝e often referred to aspirin as being almost like a regulator that you鈥檇 find on a truck, a speed regulator, so that if the truck was going too fast aspirin generally slows down most of the proliferation of responses in cells, that鈥檚 the growth responses, so that the cell doesn鈥檛 grow too fast.听 But what鈥檚 unique, if the cell has a mutation it can not necessarily die as frequently as it should.听 All cells die at some point and what aspirin does is actually it鈥檚 a bit like having that truck with the speed regulator and if you can鈥檛 regulate the speed of the cells it almost pulls it into the slow lane gravel pit, so that it comes to a stop immediately.听 So, aspirin鈥檚 got very useful effects.听 Most cells it slows down gently and for some dangerous cells that harbour very rare mutations it can kill very effectively.

Porter

What sort of research do we need to do, Peter, before we can recommend aspirin as a treatment for cancer?

Elwood

Well randomised control trials are the gold standard and it鈥檚 really a great relief that there are about six trials being set up.听 It鈥檒l be five or 10 years before those report and many patients given a diagnosis of cancer will not last to read the results of those trials.听 But I think the evidence is sufficiently strong to give the patients the choice.听 They will have a small risk of a bleed, which is most unlikely to be fatal.听 They鈥檝e got to be given the choice.听 And an increase of a year or two鈥檚 extra survival I think should be balanced by patients against the risks.

Porter

Janusz, getting a definitive answer鈥檚 going to take years, what would you say to people with cancer who might want to try aspirin in the meantime?

Jankowski

The most important aspect of this is that there鈥檚 an awful lot of patients who are on aspirin already, we think somewhere between 15-25% of the population in this sort of age group of getting cancer might already be on it.听 So, I think I would want to reassure the patients that they don鈥檛 need to come off their aspirin unless there鈥檚 a very good reason to do so, if you鈥檙e already on it consider it carefully before you come off it and let your doctor make that decision on your behalf. 听The second point I would make, is that if you consider the risk versus benefit here, the benefits are football size and the risks, particularly if you鈥檙e taking acid suppressing drugs, are golf ball size, potentially affecting patients鈥 perception of whether they should take it or not.

Porter
