Long-term quality of life after radical prostatectomy: 8-Year longitudinal study in Japan - Abstract

OBJECTIVES: To assess long-term health-related quality of life in patients undergoing radical prostatectomy.

METHODS: A total of 120 patients with at least 5 years of follow up after radical prostatectomy were included in the present study. Health-related quality of life outcomes were assessed using three questionnaires, the Short Form 36-Item Health Survey, the University of California, Los Angeles Prostate Cancer Index and the International Prostate Symptom Score.

RESULTS: A total of 91 patients (73%) responded at a median follow-up time of 102 months (range 85-123 months). Among general health-related quality of life domains, mental and role composite summary score remained stable throughout the follow-up period. At the final survey, no significant differences were observed in any of the domains compared with the age-matched average score of the Japanese population. Although the slight decrease in urinary function scores and International Prostate Symptom Score beyond 5 years postoperatively compared with 5 years, the differences were not significant. The sexual function summary score showed a substantially lower score just after radical prostatectomy and remained at a deteriorated level (P < 0.001). Responders at the final survey were more likely to report favorable general, urinary and sexual outcomes at 60 months compared with non-responders.

CONCLUSIONS: When taking age-related changes into account, general health-related quality of life seems to remain stable in the long term after radical prostatectomy: patients with favorable health-related quality of life outcomes during the first 5 years after radical prostatectomy maintain favorable outcomes thereafter.
