Rates of
unfavorable pathology following RP surgery have increased in the last 10-years.
The percentage of men with seminal vesicle involvement (SVI) following RP has nearly
doubled in 10-years, and the percentage of positive lymph nodes (N+) has more than
doubled. The percentage of extra-prostatic extension (EPE)
doubled in the last five years.
Want more evidence? The mean tumor volume increased 50%, the frequency of pathological state T3 cases more than doubled, the proportion of organ-confined cases went down from 85% to 55%, and the frequency of Gleason 8-10 increased dramatically from a couple percent to 13.2% of all cases.
BUT, while the average age of men undergoing RP stayed the same, in the time since the USPSTF’s three most recent statements about
PC and PSA mass screening, the percentage of men undergoing RP surgery for 3+3 cases has gone down dramatically…from 46% of all cases, to only 12% of all cases. Meanwhile, Active Surveillance has grown in many areas to >50% of all eligible cases.
It appears that the era of PC overtreatment epidemic for favorable-risk men is certainly on its way out.
What has been the catalyst for the heightened awareness about
favorable-risk PC cases? Was it the USPSTF? Was it Dr Schulz’s book, “Invasion of the Prostate Snatchers” which shed an unfavorable light on his peers for pushing unnecessary RPs on favorable-risk men?
Or was it great peer-to-peer encouragement given to favorable-risk newcomers to not over-react/rush to (over)treatment by the good men and women at sites like HW/PC? Probably a combination.
SO, if you hear that prostatectomy outcomes are getting worse, understand that the absolute numbers of RPs has declined, there is actually
great news behind that data. The numbers of men having surgery who didn’t actually
need surgery (and were coming out with great pathological outcomes, even if they had a minor "upgrade" to 3+4 which would have
still been eligible for AS in most cases) has declined dramatically, thus skewing an increase in the percentages of less favorable outcomes.
Great data publish in this article (somewhat misleadingly) titled “AUA: More High-Risk Pathology at Prostatectomy”
