The surgical outcome statistics--whether they are referring to BCR, longevity, or side effect profiles are notoriously difficult to find--and to determine if there is any meaning to them. Face it, surgery--all the way back to transperineal
open surgery--came first, is still probably the most common primary treatment worldwide, and therefore has the highest individual likelyhood of trouble cropping up in the future.
More and more men are choosing primary radiation--but I suspect that primary surgery still outnumbers ALL of the radiation modes combined by a large ratio. I return to what I was told at my pre-treatment consults:
As a low risk (became a low-intermediate risk after surgical pathology) patient, my long term prospectus was essentially the same whether I did surgery or radiation: something above 90% probability of going at least 10 years without BCR. Those numbers change as the risk category rises, and I suspect that for G8, 9, 10, the odds of BCR regardless of treatment mode is going to be high.
Anyway, the others have responded well: you see more BCR CASES in surgical outcomes because there are more raw number surgical cases. As a percentage, maybe it's not inflated at all. Also, in a forum like this, you're more likely to hear trouble stories that good news stories, so selection bias rolls it's way in.
