Quality of life in men with localized prostate cancer treated by radical prostatectomy or radiotherapy.

Radical prostatectomy and radiotherapy are the most commonly utilized modalities for managing patients with localized prostate cancer. Each has effects on quality of life that are important in decision making. Long term side effects of these treatment modalities include urinary, bowel and sexual dysfunction, and have been documented. Comparison of the side effects of these different modalities continues to be explored, emphasizing their effects on quality of life (QOL) from the patient's viewpoint. Questionnaires were mailed to 224 eligible patients and a response was elicited in 161 men (72%). The final number of patients who completed all the questionnaires was 151. Of these, 73 (48%) had radical prostatectomy and 78 (52%) had radiotherapy. General well being measures demonstrated a definite advantage favoring men treated with radical prostatectomy. Prostate cancer specific QOL measures were similar among men treated with surgery or radiotherapy. Radiotherapy treated men were slightly more likely to report bowel-related problems than surgically treated men. Urinary QOL measures were no different between treated groups. Surgically treated men reported lower level of sexual function than radiotherapy treated men.
