Focal HIFU vs Surgery

User
Posted 01 Jan 2021 at 17:16

Hi everyone 

I’ve just been diagnosed with prostrate cancer so everything is still a blur and new to me 

So posting this and looking for anyone with similar position 

Basically any advice would help 

I’ve been given few options , like radiotherapy, surgery and HIFU 

Although the doctor say radiotherapy isn’t really for me because of my age 

Not sure what’s best for me at this stage 

So anyone who had HIFU , please share your experience or surgery 

Hope to hear from you guys 

Thank you

HIFU doesn't have fantastic results as a primary treatment but the side effects can be less dramatic so if you are happy to accept that you may need to repeat the HIFU in the future, it could be a good option. As I have just posted on another thread, the decision making should be a) which treatment gives me the best chance of remission b) can I live with the known and potential side effects and c) if not, which is the next best option but with risks that I can live with?

You can download the toolkit from this website and read about the different treatments and there is a helpful pros/cons sheet that you can use to list what is important to you and clarify your thoughts.

Hi Mickey,  I have been reading your story and like many on here deciding what form of treatment to choose isn't easy, my head was just all over the place and I couldn't see the light at the end of the tunnel at all.   My Mrs told me I was focused on the wrong things ie ED and she wasn't bothered if my dick worked or not as what was important was that I was around for many years to come (men and women are definitely wired differently lol )     My consultant recommended full removal but he was a surgeon, however I was told that whatever route I went down they was a high chance they could cure the cancer and after an appointment with an oncologist I have decided on the radiotherapy route.   So far I have had something fit called a spaceOar to move the bowel away from the prostate to reduce the side effects and damage to the bowel from the radiotherapy and all of the planning has been done ready to start on the 18/1 with 7 sessions every other day.    I did look at focal therapy and almost went that route but it would seem that you would need to be prepared for this procedure being repeated.  The plus side is that the side effects seem to be a lot better.   I noticed one of the guys suggested you put more details on here for your results as every treatment clearly will not suit everyone.   There might be a good reason why removal is recomended and why they have not offered radiothereapy.    I had the advantage of having time on my hands to make a decision as I have previously been under surveillance for the last 4 years and the cancer is fully contained.   In my own case once I had decided on the route it was like the weight of the world was lifted but don't be pushed into any decision without asking loads of questions.    I have had nothing but excellent medics to deal with who I couldn't fault on anything.

 

All the best

When I had my appointment with the oncologist who spent almost an hour with me discussing my case and all of the options (I also had a list of questions a mile long) I just felt very confident that radiotherapy was going to be just as effective as removal,  I'm 63 and this was first spotted at 58/59 but it has been confirmed it is totally confined in the prostate.  Grade 2 Cancer, T2 NO 50% max core involvment what ever all of that means lol.   Logic told me to just get it removed but the oncologist said it was always possible that tissue could be left behind by surgery and the course I was going down was just effective infact I read somewhere that in the distant future Proton Beam may replace surgery.    As for the spaceOar its needed to reduce the side effects but  again I'm sure I have read somewhere that the NHS are not going to provide this after March because of the cost but I could be totally wrong on this.   

Back to the side effects of Radiotherapy, before I had the appointment I had so many people tell me not to go for it and it would destroy my immune system etc etc but the onocologist totally put my mind at rest on that one.   I also have a friend who is a chiropactor and he said he had many clients that had all gone through RT without any major issues.  The thing is Mickey we are all different and also have different diagnosis,  I'm the sort of person that needs to look into the whites of someones eyes that is giving me this information and then I go with my gut feel.   As I have said before the preparation for this so far has been first class and I'm becomming totally fascinated with what they are doing.   I even had my paper pants ripped off in an operating theatre by a nurse as the surgeon couldn't find a pair of scissors to cut the sides, so even at my age I have experienced something new as I've never had my pants torn off :-).    I just have my fingers crossed that I have made the right decission which I feel I have and I will deal with everything else as it presents itself.   I'm lucky that this is not going to kill me and recently a colleague of mines father in law broke a rib and after they had X rayed him and took bloods etc they discovered he had advanced prostate cancer and he had no idea :-(

Before I posted I did read the unsupported alternative view of Alan Doherty who we know is a top surgeon but not a HIFU specialist. Even he agreed there was a place for HIFU and suggested that results within the trial were so good becuse the men were carefully selected and treated by highly competent clinicians. This should of course always be the case but I take the view that practitioners of HIFU are in a better position to decide whether a man is suitable than a surgeon lacking experience in the procedure. In any event, some Surgeons cherry pick cases to show good perssonal results. There comes a time in many cases where a decision has to be made between surgery or RT and arguements can be made for and against either form of treatment. In the same way, a decision has to be made as to whether the significant cancer in an individual case can be reasonably treated with HIFU (or another form of Focal treatment) or whether it calls for more radical treatment.

Bio, I'm in the exact same position,  got told I had cancer 2/3 weeks after my 50th birthday. I have no symptoms so cant get my head around it. I'm unfortunately booked in for a prostectormy on 21st. Desperately looking for an alternative ( I've put £1000's worth of cannabis oil up my bum! All donated, I didn't pay!!!) But my psa has doubled & the cancer team say they go on the biopsy more than anything else & that was conclusive..... apparently! I've not heard of focal but really, I have to self isolate from Thursday & preop tomorrow! I've run out of time to do anything else. At least you got your head in the game & are able to look & think, I missed my chance.  Good luck & check it all out if u got time, I wish I had been a bit more proactive.

As a recent primary HIFU patient, I have been interested in the conversations and have read the studies referenced by Old Barry and Lyn. They are extremely upto date and useful. It’s only here from our ‘experts’ that I get to know where to find these studies.

Any doubts I have that I have had the right treatment has gone. This may be only in my case as the 2019 study points to HIFU best for older (I am 76), low risk who has a partial not whole gland HIFU.

The 2018 Imperial College results for HIFU compare very favourably as Barry has already said.

It is true that the rate of positive biopsy after HIFU from the October 2020 (Mao.,Chao) results of 1698 patients was 14%to 37.5%. However what pleases me is that they say after partial-gland HIFU, the mean PSA nadir was 1.9 to 2.7 and I have just received my 3 monthly post HIFU of 2.00 which I was not sure about but can now be relieved that I am in good company.

Great result, Bill. In my mind, HIFU is positioned between active surveillance and the radical treatments - a good option for someone who might be suitable for AS or is just beyond the threshold and doesn't generally suffer from anxiety.

In all honesty, if I could turn back the clock I would have asked Stan to consider HIFU once he had point-blank refused to have RP or RT/HT - especially if we had known that his AS would not be correctly managed. He was a very laid back kind of guy and even if he had had to repeat the HIFU, he might still be with us.

Sorry about stan

I was booked in for my prostectormy but it got cancelled,  it's now back on but I have a consultation Monday night with the dr who does hifu,  for me at 50 if I can save my penis for a few years a £13000 debt its worth it. I hope I'm eligible,  I'll let you know. 

All the information posted has been very helpful. I'll be re reading all this Monday night when I need to make a decision.

"I have seen you mention a PSA after treatment of 2.15 as a threshold or something, and wonder what that was. But probably nothing to do with HIFU."

After RT, a man still has a prostate and the healthy cells can replicate and regenerate so the accepted stance is that after successful RT the PSA shouldn't go higher than 2.0 plus the lowest reading the person has ever had (in the post you saw, the person had had a PSA reading of 0.15 while on HT).

In your case, there has been less damage to the prostate so it is expected that your 'healthy' PSA will be a bit higher than if it had all been zapped to a frazzle.

Lyn makes a valid point in saying about the higher PSA level likely to be found after RT due to healthy or recovering cells producing PSA than with Prostatectomy. However, whereas RT damages some good cells all the way to the target, HIFU damages only the actual target area itself so there is going to be even more good cells remaining in the Prostate than with RT. It follows that PSA levels can be higher with HIFU.

It is most important that the HIFU probe which is located in the rectum is in a good position to focus on the tumour. A major study suggested that results were better where the cancer was in the Posterior than the Anterior zone.

As regard the question posed by Michael, I think each case has to be looked at very carefully. When diagnosed in late 2007 I had a T3a and it was thought RT would stand a better chance of dealing with this than surgery or HIFU. In the intervening years all treatments have improved, as have scans and biopsies but I nevertheless feel there is still a better chance of RT zapping any cancer cells on the point of escaping as it is difficult to know there disposition.. So the way I see it is that RT can go beyond where HIFU or the knife can but if you are prepared to pay for HIFU, it might work for you but if it doesn't, any escaping cancer cells might have migrated further, so any follow up RT then considered necessary might prove less effective. Even having surgery or RT now is not certain to eradicate your cancer.

I wish you well in making your decision and hope it works well for you.

Thanks Barry. Yes not bothered now with my PSA result after HIFU. You have had both RT & HIFU so realise now why you have to watch your PSA more closely. By the way sent you a private message some time ago but your message box was full. Anyway seems more important to get the vaccine at the moment at our age.

It’s good advice you and Lyn have given Micheal. At his age it may not be wise to rush into a HIFU, especially if at £13000, it might have to be repeated. If I was 50 again I would certainly wait for a more permanent solution.

You've got to laugh bill or what's the point.  I'm glad I have options,  so gutted there all horrible decisions but as my wife says the bad bits happened,  I have cancer,  now just what to do about it. 

We put so much trust in the experts & what they say, I've not a clue what to do apart from I have to do something, hifu seems to have the least side effects & they rang Monday when I had no treatment plan in place, it felt like I was supposed to do it! Let you know after Monday.

Do you have any data on that, Lyn? Several recent papers seem to indicate that results are comparable to radical prostatectomy and radiotherapy. It is inevitably short-term because the treatment hasn't been available long enough to track beyond ~10 years?

It has been available in the UK since 2002 but the outcomes in terms of progression free status at 5 and 10 years are not great and I guess the fact that 18 years on, it is still not an established radical option on the NHS speaks volumes. The recent papers I have seen have either been funded by interested parties and are not peer reviewed OR they do not separate out the data for HIFU as a salvage rather than primary treatment or indicate whether the procedure was for a first, second or third attempt. ED is still a bit of a problem and the risk of fistula is higher than might be considered acceptable by many patients. There is no doubt that HIFU is an excellent salvage treatment for some people.

HIFU has been available in Europe for rather longer, particularly in Germany, and no doubt one of the members who had HIFU as a salvage treatment can give you more info.

The biggest disadvantage with HIFU is that it is a niche form of treatment where the cancer is confined to the Prostate and preferably small in volume and limited in deposition. Specialists will readily admit that there becomes a point where surgery or RT becomes more appropriate. There are situations where it is completely successful done once or repeated but otherwise it is highly likely to set the cancer back for a time so at some point a decision may have to be taken on whether to remove the Prostate or treat it and any other treatable but affected areas with RT.

The biggest advantage is that the treatment is quickly accomplished with fairly short recovery time and generally less severe side effects than other radical treatments. Risk of a Fistula is extremely very rare now. The lady surgeon who administered my HIFU (as a salvage procedure for failed RT), is reported as not having one Fistula case in the several years and hundreds of HIFU procedures she has done. All forms of treatment have been refined or improved over recent years including HIFU. There is now a different method of administering HIFU called TULSA PRO that looks promising but I don't think it is available in the UK yet and only time will show how effective an alternative this is to the usual HIFU.

This is an interesting interview although I don't understand the reason for the large gaps in the text. https://www.canceractive.com/article/professor-mark-emberton-on-high-intensity-focussed-ultrasound-or-hifu

Hhhhmm - Prof E is one of our greatest leading lights on urological cancers but this article was published in 2011, is aimed at an American readership and promotes his private practice rather than NHS work. It is also worth noting that his second set of trial data was published in 2013 - and still HIFU is not a mainstream option.

As I already said, I think that if a man has either the money or the blessing of being offered it on the NHS, has a small, clearly delineated tumour and is comfortable with the possibility of needing to repeat it in the future, it seems a no-brainer to give HIFU a go. But anyone who would be distressed by a recurrence should think very carefully.

Could you possibly post references to some studies showing poor outcomes at 5 and 10 years?

I imagine you will inevitably get conflict of interest sometimes e.g. Sonacare sponsored the research behind the 2018 paper in European Urology which indicated that primary focal therapy for select Gleason 6-9 patients was as effective as surgery or radiotherapy in the medium term. However, that research was also funded by the Medical Research Council, and published in an international journal with a high impact factor. That suggests the methodology was robust, and that it would be difficult for Sonacare to manipulate the data on collection? As well as UCL and Imperial, there was significant NHS involvement in the study.

Key players like Hashim Ahmed are highly respected researchers. Ahmed also pioneered the use of multi-parametric MRI with biopsies.

Yes, shows how advanced Prof E's thinking was and remains the case.  He naturally tailors his interviews to his audience whether it be UK or International, Clinicians or Lay persons/Groups but the message is basically the same.  Many consultants do private work as well as for the NHS.  Whilst a patient at UCLH, I had a one to one discussion with him about Focal Therapy in general and my case in particular and it didn't cost me a penny.  Why would he try to promote HIFU on the NHS when other than for private patients NICE have restricted it's use to trials and there is no shortage of referrals for these?

The reluctance of NICE to approve HIFU because of lack of long term analysis is obviously one of the reasons it has not become main stream.  Additionally, surgeons who have studied hard to become proficient in removing the Prostate directly and some also with the robot, are not lightly going to change to a less demanding procedure, especially one that is not supported by NICE for the NHS.  It's also the case that the UK is slow to accept change.  An example of this is Proton Beam which although having more success in some other cancers, than PCa has been available in the USA, Germany, France Italy and many other countries for many years.  Indeed the clinicians in the UK even tried to stop Alesha King from have life saving Proton Beam treatment in Prague which he had after his parents were released from a European Arrest Warrant.  So it's no surprise to me that we lag behind other countries when it comes to Focal Therapy amongst other things.

There is also anecdotal info if you want it - the very small number of members here who have had primary HIFU some time ago did not achieve remission; those who had salvage HIFU have almost all seen further recurrence I think. On the other hand, if you are a member of YANANow, there are a number of men there who appear to have had great outcomes from HIFU (although I think the vast majority were very early (T1a) diagnoses)?

My apologies Mickey - I can't find the pros & cons sheet on the website either. It used to be part of the toolkit :-(  I notice though that when you download each of the information sheets (about the different treatments) they do still list the advantages / disadvantages of each treatment.

No - radiotherapy increases the risk of you developing bowel cancer from around 6.6% to around 8% - that's not massive.

Extract from report on largest and most recent study on HIFU https://www.sciencedaily.com/releases/2018/07/180705114140.htm

'The scientists also tracked the number of patients who needed further treatment following HIFU, (such as surgery or radiotherapy), to treat any cancer cells that had returned. They found 10 per cent of patients needed further treatment by five years, which is comparable to number of patients needing further treatment after surgery or radiotherapy (5-15 per cent)'

We will have to see what the 10 year analysis shows with the Sonarblate which now seems to be preferred in the UK to the Ablertherm referred to in analysis in earlier studies.  Also, in these other studies not all candidates may have been suitable candidates for HIFU.  Furthermore, there were more cases where HIFU was directed at the whole gland whereas now it is more used only for 'significant' tumours which increases its effectiveness.

A crucial aspect is that men are carefully selected for HIFU because the cancer can become so difficult to deal with through location, volume or intensity that more radical treatment becomes more appropriate.  But for suitable men, the overall possibility of a milder treatment that can be repeated or in need followed by more radical treatment, coupled with the less severe side effects of HIFU could make it a preferable option.
