Background: We performed a retrospective survey of general and disease specific health-related quality of life (HRQOL) after radical prostatectomy (RP) and external beam radiotherapy (XRT) in Japanese men. Methods: A total of 186 patients underwent RP and 78 underwent XRT for clinically localized prostate cancer between 2000 and 2002. We measured the general and disease specific HRQOL with the MOS 36-Item Health Survey and the University of California, Los Angeles Prostate Cancer Index, respectively. Each treatment group was further divided into four subgroups according to the time scale. Results: Patients from the RP group were significantly younger than those from the XRT group. The tumor characteristics differed significantly in their distributions among the treatment groups. Patients undergoing XRT had low scores in most of the general measures of HRQOL just after treatment, but after 6 months there were no differences between the treatment groups, except for the physical domains. The RP group was associated with worse urinary function, whereas the XRT group had worse bowel function and bother during the first 6 months after treatment. Thereafter, however, urinary and bowel domain did not differ between the groups. Both groups reported poor sexual function, although the RP group scored lower sexual bother. Conclusion: The patients who underwent RP had significantly worse urinary and better bowel function than those treated with XRT. Both treatment groups had decrements in sexual function throughout the post-treatment period; careful attention should be paid to this side-effect in preoperative counselling, especially in younger patients, regardless of the primary treatments.
