We read with interest the recent article by Merglen et al1 comparing prostate cancer treatments but have concerns regarding the analysis method used and conclusions reached. This retrospective study used the Geneva Cancer Registry and analyzed clinical outcomes of patients treated between 1989 and 1998 for prostate cancer. The authors concluded that radical prostatectomy patients experienced a lower rate of prostate cancer deaths than did those undergoing radiation therapy, observation, or hormonal therapy.
