They found a 55% recurrence rate in salvage radiation (SRT) patients. This confirms several other studies around the world that show in the long term, most salvage radiation patients will show at least biochemical recurrence. (In the short run, it's just the opposite) . However, the study also showed very few prostate cancer deaths during the followup period. And the study confirmed other research since 2004: pre-SRT PSA level is a critical factor in predicting the outcome of salvage radiation. The lower your PSA at the time of salvage radiation, the better. The takeaway? If you're considering salvage radiation, don't dally.
