Background:
Long-term subjective outcomes of prostate cancer are relatively unknown. The Oregon Urology Institute (OUI) has been collecting subjective functional outcome data to help determine the long-term subjective outcomes of prostatectomy vs radiation therapy.
Methods:
Patients treated at OUI completed interval post-treatment questionnaires that assessed: urinary, bowel, sexual, and hormonal function, and overall treatment satisfaction. Two cohorts were established: prostatectomy vs radiation. Results from each cohort were compared and analyzed with a linear mixed effect model.
Results:
Our longitudinal dataset includes a prostatectomy cohort of 410 patients and radiation therapy cohort of 416 patients surveyed at the 3-month interval, but the number of patients decreased after each time interval (ie 3, 6, 9, and 12 months and then annually for up till 14 years post-treatment). Urinary and sexual functional scores decreased by 4% and 8% after radiation, whereas prostatectomy had a 5% and 13% increase over time post-treatment, respectively. Over time, patients treated with prostatectomy were found to be more satisfied with the outcome of their treatment than patients receiving radiation therapy.
Conclusion:
Prostatectomy and radiation therapy had impacts on quality of life measurements that emphasize the importance of making the best-informed decision in each unique situation.
