Longer life with prostate surgery: study

Between October 1989 and December 1999, researchers randomly assigned 695 men with localised prostate cancer to either radical prostatectomy or watchful waiting.

Participants were eligible for the study if they were younger than 75 years of age and had a life expectancy of more than 10 years with no other known cancers.

Participants were monitored annually until December 2012, by which time a total of 447 men enrolled in the study had died, including 200 men from the radical prostatectomy group
