Have made contact with MM Barry.
Just to add that salvage treatments include surgery; Cryotherapy, HIFU & HDR Brachytherapy as possibilities.
My surgery was no different to a standard robotic RP experience & I was home the next day. Rarely the prostate might be more difficult to remove & open surgery might ensue to help the surgeon. Newer scans give a better picture of the likelihood of problems prior to treatments.
The NHS is unlikely to offer salvage treatments unless benefit is anticipated. This may only be extended survival but this can be important to some. For others the higher risks of side effects may put them off. A personal decision.
In other cancers. it is common for one treatment to follow another immediately. e.g. surgery, then R/T , then chemo. Or,chemo, then surgery, then R/T.Or, surgery, chemo & then R/T . Recurrence is not waited for. Each treatment adds to survival chances/time.( See NHS Predict website for example for B.Ca. ). I doubt this is viewed as a second bite of the cherry by the medical world who follow such tried protocols. We are just way behind with P.Ca. on the best types & sequences of treatments for each case. We are often offered choices at diagnosis simply because the medics do not know which treatment will give the very best result .
R/T statistically still shows a higher recurrence percentage than surgery cases for P.Ca. Even if figures include less aggressive cases on the surgery side. So there is a place for salvage treatments post R/T and these are being evaluated for best results.
