Long-Term Subjective Functional Outcomes of Prostate Cancer: Prostatectomy vs Radiation.

Area of Science:

• Urology
• Oncology
• Patient Outcomes Research

Background:

• Long-term subjective outcomes after prostate cancer treatment remain understudied.
• The Oregon Urology Institute (OUI) has gathered data to compare prostatectomy and radiation therapy outcomes.
• Understanding long-term effects is crucial for patient decision-making.

Purpose of the Study:

• To compare the long-term subjective functional outcomes of prostatectomy versus radiation therapy for prostate cancer.
• To analyze patient satisfaction and functional recovery following different treatment modalities.

Main Methods:

• A longitudinal study comparing two cohorts: prostatectomy (410 patients) and radiation therapy (416 patients).
• Patients completed interval questionnaires assessing urinary, bowel, sexual, and hormonal function, plus overall satisfaction.
• Data were analyzed using a linear mixed-effect model over a 14-year period.

Main Results:

• Urinary and sexual function scores declined post-radiation (4% and 8%), but increased post-prostatectomy (5% and 13%).
• Prostatectomy patients reported significantly higher treatment satisfaction over time compared to radiation therapy patients.
• Patient numbers decreased over time intervals, but the study tracked outcomes up to 14 years.

Conclusions:

• Both prostatectomy and radiation therapy impact quality of life and functional outcomes.
• Informed decision-making is essential, considering the distinct long-term effects of each treatment.
• Prostatectomy may offer better long-term functional recovery and patient satisfaction for prostate cancer.
