This showed up in my inbox and I found it interesting.
It appears to be focused on initial treatment rather than a salvage setting, and showed that even for those newly diagnosed with advanced prostate cancer that had already spread, there was benefit to radiating the prostate:
“The initial 2018 findings of this arm of the STAMPEDE trial were slightly surprising. Previous thinking was that if the cancer had spread then the horse had bolted and there was no point in shutting the stable door by treating the original disease site. These long-term results have confirmed that this is not the case, and by treating the original site after the disease has spread, some men with prostate cancer lived longer than those on hormonal therapy alone. This could potentially benefit people with other cancers that have spread to other parts of the body too.”Professor Nick James, Professor of Prostate and Bladder Cancer Research at the ICR, and Chief Investigator of the STAMPEDE trial
