The title to the article makes no sense.
In fact, the whole article seems a bit senseless to me.
The "study" runs from 1987 to 2004.
During which time 3% of RP patients died as a result of PCa.
And they conclude that RP leads to a median 19 year survival rate.
It says they were treated from 1987 to 2004. Not that the study started in 1987 and ended in 2004. The study obviously ran to this year as far as survival, but excluded anyone treated after 2004.
