Thank you everyone for your kind words - they are really appreciated.
I only post this information here so that others who may be interested can be informed. I find it unethical that none of the charities in the UK will carry official information about any therapies that are not offered via the NHS.
My wife is a nurse and has worked for the NHS for decades. I know how hard she and very many of her colleagues work, how dedicated they are and how much they care for their patients. I also know from her experience how stifled in bureaucracy the NHS is, how wasteful it often is and how difficult innovation and learning is due to an overriding culture of hierarchy and dogma that often strays into outright bullying.
I mention this in this thread because no one who consults with an NHS oncologist or researches information via the UK Prostate Cancer charities is likely learn anything about innovative therapies such as Lu177 617 PSMA. To my knowledge there are experimental uses of this and similar radionucleide therapies and, in some cases, Phase 3 trials, in the US, Germany, Finland, Australia, South Africa and even Myanmar!
I would urge anyone meeting an oncologist with metastatic prostate cancer to demand information about new and innovative therapies, whether they are licensed for use in the NHS or by NICE or not. Ultimately we have the absolute right to take decisions about our lives in our best interests. In order to do that we have to be fully informed.
Whatever the eventual outcomes might be in my own case, I sincerely hope that anyone who reads about them is motivated to research, learn and demand more from their clinicians.
