Radical prostatectomy versus watchful waiting in early prostate cancer.
BACKGROUND In 2008 , we reported that radical prostatectomy , as compared with watchful waiting , reduces the rate of death from prostate cancer . After an additional 3 years of follow-up , we now report estimated 15-year results . METHODS From October 1989 through February 1999 , we r and omly assigned 695 men with early prostate cancer to watchful waiting or radical prostatectomy .  Follow-up was complete through December 2009 , with histopathological review of biopsy and radical-prostatectomy specimens and blinded evaluation of causes of death . Relative risks , with 95 % confidence intervals , were estimated with the use of a Cox proportional-hazards model . RESULTS During a median of 12.8 years , 166 of the 347 men in the radical-prostatectomy group and 201 of the 348 in the watchful-waiting group died ( P=0.007 ) . In the case of 55 men assigned to surgery and 81 men assigned to watchful waiting , death was due to prostate cancer . This yielded a cumulative incidence of death from prostate cancer at 15 years of 14.6 % and 20.7 % , respectively ( a difference of 6.1 percentage points ; 95 % confidence interval [ CI ] , 0.2 to 12.0 ) , and a relative risk with surgery of 0.62 ( 95 % CI , 0.44 to 0.87 ; P=0.01 ) . The survival benefit was similar before and after 9 years of follow-up , was observed also among men with low-risk prostate cancer , and was confined to men younger than 65 years of age . The number needed to treat to avert one death was 15 overall and 7 for men younger than 65 years of age . Among men who underwent radical prostatectomy  , those with extracapsular tumor growth had a risk of death from prostate cancer that was 7 times that of men without extracapsular tumor growth ( relative risk , 6.9 ; 95 % CI , 2.6 to 18.4 ) . CONCLUSIONS Radical prostatectomy was associated with a reduction in the rate of death from prostate cancer . Men with extracapsular tumor growth may benefit from adjuvant local or systemic treatment . ( Funded by the Swedish Cancer Society and the National Institutes of Health . )
