Hello Barry
As always I wish you and all men a speedy and sustainable recovery from cancer whichever treatment pathway they selected and thanks again for your detailed reply.
Just to correct, the Study by Bhat (2021) is a US Study not the German Study you refer to which is by Duwe (2023).
Im pleased professor CM who treated you at a London Hospital has the experience of c.900 HIFU operations. The industrial scale of HIFU treatment at the hospital is not at all surprising to me. Her boss, professor ME, the Director of Surgery at the unnamed hospital appears to have been engaged in promoting the performance of HIFU equipment on behalf of SonaCare, the manufacturer at International Conferences. I say 'promoting' because use of failure rates of the Sonablate 500 device backed up actual research would not be to 'promote' its use, but simply to give specialist advise from an expert in the field. In this example in 2017, ME quotes the (as far as I can see) an unsubstantiated 15% failure claim for the device in exactly the same terms used by Hashim Ahmed in the 2014 Seminar Article;

Here again is Ahmeds' 2014 Seminar Article

The issue I have is much much wider. As we said, Ahmed is Chair of Focal Therapy Uk, in charge of the HEAT Registry which is approved by NICE to record data on the success of the HIFU procedure in the UK. At the same time, he is being paid by "SonaCare Medical/Focused Surgery/Misonix Inc/UKHIFU (manufacturers and distributors of the Sonablate 500 HIFU device) for travel to conferences/meetings and for training surgeons in the use of the Sonablate 500 HIFU device" as well as many other private and public grant sources. All well and good on the face of it. As you correctly say, developing and refining cancer treatments should involve public and private interests and expertise working together in the best interests of patient care. There is nothing wrong here except, I can find no research basis for the claimed 15% failure rate of primary HIFU Ahmed quotes. In his 2014 he refers to "Current data from more than 3,000 men treated internationally.." as the data source of the assertion, yet the HEAT Registry was only launched on 11th April 2017 by SonaCare with an initial 1500 patients. So he didn't get his data from the HEAT Register. It may have come from the US and probably from SonaCare themselves who I believe operate a fee-for-use and maintenance of the equipment (I may be wrong). So they would be collecting usage and failure data.
Coming back to washing machines, if you wanted to sell many many more machines, making over-optimistic claims about their performance would attract millions more customers, boosting profit margins. I have to say, I find the fact I was advised in exactly the same terms used by Ahmed in 2014, repeated by professor ME in the above you tube clip in 2017, and written in a letter to my GP in 2021 troubling to say the least.
I don't have the relevant medical training or expertise in statistical analysis to interrogate research studies in any depth. I simply read the results of 9 Studies completed between 2017 and 2023. Here is my quick summary of reported failure rates of primary HIFU, partial ablation:
2017 Garcia et al (Uni Paris-Descartes, Memorial Cancer Centre NY, USE, CEMIC Uni Hosp. Beunas Arries, LapPaz Uni Hosp. Madrid - Reported primary HIFU failure 28.1% at 6 yrs
2018 Guillaumier et al (UCLH, Imperial + UK Hospitals, Uni Med Centre, Utrecht, Netherlands) - Reported primary HIFU failure 37% at 5 yrs (noted in Editorial comments in 2019 Thompson et al-Table 3)
2019 Marconi et al (UCLH, Guys, Kings, Imperial) Reported primary HIFU failure 26% at 1 yr; 52% at 2yrs, 64% at 3 yrs.
2019 Thompson et al (UCLH with Barts, Q Mary, Uni Oxford) Reported primary HIFU failure 37.1% at 2.4 yrs
2019 Stabile et al (UCLH, Imperial, CharingX, San Raffaele Uni, Milan) Reported primary HIFU failure 15% at 2yr; 41% at 5yrs, 46% at 8 yrs.
2020 Thompson et al (UCLH) Reported primary HIFU failure estimated 35% -40% over 12yrs
2021 Bhat et al (Sunt Med Uni, NY, USA) Reported primary HIFU failure generally estimated 35% -42%
2022 Reddy et al (Imperial, UCLH, UK Hospitals, Utrecht, Netherlands, Cancer Centre in Luzern Switzerland) Reported primary HIFU failure 31% at 7 yrs
2023 Duwe et al (Johannes-Gutenberg Uni with Carl-Gustav-Carus Uni, Germany Reported primary HIFU failure 37.93% at 2 yrs
15% failure rate seems to be more of a sales pitch from this research. All this does not paint a happy picture given that 6,177 primary HIFU procedures were undertaken at the unnamed London Hospital referred to above (my FOI established this data).
Q1/ Would you take odds of 15% failure with the option of a second HIFU to avoid radical treatment with associated morbidity when your also told the other option is to 'watch' Gleason 4 cancer and see if it grows? I would and did. But I was not counselled of the collateral damage to nerves and pelvic floor muscles and associated problems this causes later in radical treatment; or given the option of a primary prostatectomy or radiotherapy at that stage- see Q2/
Q2/ Would you take odds of 35-42% failure when its also pointed out incontinence and recovery of erectile function are much worse due to HIFU-induced fibrosis of nerves and muscles if you then need to go onto radical treatment, and if your also given the option of a primary prostatectomy or radiotherapy instead of taking the HIFU gamble? I would not and would definitely have taken the primary prostatectomy route.
So you see the wider picture is, there are serious questions around the care offered by the NHS to prostate cancer patients at this hospital and perhaps other "Centres of Excellence in HIFU" which may mean up to, say 3000 to 5000 men may have taken a treatment pathway they would not otherwise have chosen due to lack of, and/or inaccurate counselling, disabling their informed consent.
We should also consider the many tens of millions of pounds of NHS budget spent on potentially abortive MRI and PET scans, biopsies, consultations and hospital stays; and the extension of cancer treatment for those men with the amplifying effect we know it has on stress for them and their families. That is why I feel strongly about this.
