There have been several threads in this forum dealing with the effects (risks) of choosing a less-experenced vs. a more-experienced surgeon. I came across this article:
www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2637145 published in 2008 showing an improvement in outcome (being free of biochemical recurrence, i.e., rising PSA for 5 years):
1) for patients with organ-confined disease, new surgeons 85%, 2000 surgeries 98%
2) for patients with extra capsular extension, new surgeons 53%, 2000 surgeries 65%
In both cases the improvement flattens out at about
300-500 operations.
It's possible that there's some effect in there due to (maybe) more experienced surgeons taking tougher cases, but the article doesn't comment on that. There's more fine print in there if you care to dig into it.
