The stats that MJ posted are from the pair of studies posted in the New England Journal of Medicine that raised quite a bit of controversy. In one study it showed no benefit in the US of screening and in the other it showed a substantial benefit to screening in Europe.
The actual number used in those studies showed that after a median of 9.2 years it would take screening of 43 men to save one life.
But I don't like short term studies because they do not mature enough to provide useful data. And this one proved to be exactly that. Have a look:
prostatecancerinfolink.net/2011/02/13/truth-in-screening-how-many-men-to-screen-and-treat-to-save-a-life/Simply put, using the exact same study and extending the collected data by about
two and a half years, we have stats that almost completely disagree with the first release of the study. And it is my contention that if we look at it again in five years we will see even more impact on the data.
So MJ's post was correct ~ two years ago. But just like all those other screening, active surveillance, and local therapy studies ~ the criteria should be extended to the end point of mortality.
Tony's Soapbox ~ Anything short of that is a story about
PSA control and not survival benefit. I do not contend that we need to have population based screening, but rather that we need to be doing smarter studies...
