Hi,
a scandinavian study reported e.g. in www.livescience.com/43898-prostate-cancer-surgery-survival.html. Full study in March 6, 2014 issue of the New England Journal of Medicine.
I don't believe this outcome is fully valid for AS vs. RALP now a days. These patients where diagnosed an treated 24 years ago! But my personal belief is still that if you are *young and healthy*, "get rid of it", there is a good chance for small SE when treated with surgery early.
This text copied from the article above:
"Young men with early-stage prostate cancer who undergo surgery right away, instead of waiting to see if their cancer progresses, may lower their chances of dying from the disease over the long term, a new study from Scandinavia suggests.
In the study, men with localized prostate cancer (cancer located only inside the prostate gland), who underwent surgery called a radical prostatectomy were 44 percent less likely to die from the disease over the next two decades, compared with men whose cancer was observed through "watchful waiting" to see how it progressed."
You are right, 24 years ago is a long time! Still,

However, the reduced risk of dying from prostate cancer was seen only in men who were younger than 65 at diagnosis, or whose tumors had a medium risk of spreading (as opposed to a low or high risk)
So the reduced risk did not apply to low risk men who had surgery, the typical AS candidates. (Nor sadly, to the high risk like me).

The study involved 695 men with early-stage prostate cancer who were randomly assigned to receive radical prostatectomy or watchful waiting between 1989 and 1999, and followed for up to 24 years. (BillyBob's question: what were the Gleason scores? Were some men with higher G scores randomly assigned to just be watched, or were all 695 of these guys G6 men? It appears to me they were randomly assigned regardless of risk category, is that right? If some higher Gs were assigned watchful waiting, no wonder that the men who had surgery did better! And amazingly, treated or untreated, the solid majority did not die of PC. Which is not to say that they did not suffer from PC )
During the study, 200 men in the surgery group and 247 men in the watchful-waiting group died. Of these, 63 deaths in the surgery group and 99 in the watchful-waiting group were due to prostate cancer.
An earlier version of the study found benefits to surgery, but in the new study, which had a longer follow-up time, the benefits were even more pronounced, Rider said. Eight men in the study needed to be treated with surgery to prevent one death from prostate cancer, the study found.
Wait and see
Although older men and those with low-risk prostate cancer who underwent surgery did not have a reduced risk of dying from the disease, they did have a lower risk of their cancer spreading, and were less likely to need hormone treatments compared to those in the watchful-waiting groups. Both cancer spread and hormone treatments are factors that can affect a person's overall quality of life, the researchers said.
Older men, and those with low-risk prostate cancer, primarily died of causes besides their cancer, Rider said.
The study also found that 40 percent of those in the watchful-waiting group who were still alive two decades later had not needed any surgery or other treatment for their cancer.
This finding "really shows that there is this large percentage of men with localized prostate cancer who can live for a very long time without any sort of major health consequences of their diagnosis," Ridertold Live Science.
"That points to the potential for over-treatment in these men," she said. In other words, if all men underwent surgery, some would receive a treatment they didn't need. Moul noted that the "watchful-waiting" approach used in the study is different from the concept of active surveillance that doctors use today to observe prostate cancer, which involves more frequent assessment of the tumor progression. So it's not clear how well the study findings translate to today's patients, Moul said.
