Radical prostatectomy significantly reduces prostate cancer mortality and extends life expectancy by nearly 3 years for men with localized disease. High Gleason scores and extracapsular extension predict a worse prognosis.
Area of Science:
- Urology
- Oncology
- Clinical Trials
Background:
- Radical prostatectomy is known to reduce mortality in localized prostate cancer.
- Evidence from randomized trials with long-term follow-up is limited.
Purpose of the Study:
- To evaluate the long-term effects of radical prostatectomy versus watchful waiting on mortality and metastasis in localized prostate cancer.
- To assess the prognostic value of histopathological measures in predicting outcomes.
Main Methods:
- A randomized trial involving 695 men with localized prostate cancer comparing watchful waiting to radical prostatectomy.
- Long-term follow-up data collected through 2017, with intention-to-treat and per-protocol analyses.
- Estimation of cumulative incidence, relative risks, and years of life gained; Cox proportional-hazards model for prognostic evaluation.
Main Results:
- Radical prostatectomy resulted in a significant reduction in prostate cancer death (relative risk, 0.55; P<0.001) and an absolute risk reduction of 11.7%.
- A mean of 2.9 extra years of life were gained with radical prostatectomy at 23 years of follow-up.
- Extracapsular extension and Gleason scores >7 were highly predictive of prostate cancer death.
Conclusions:
- Radical prostatectomy offers significant survival benefits for men with localized prostate cancer and good life expectancy.
- Histopathological features like Gleason score and extracapsular extension are critical prognostic indicators.
- The study provides robust long-term evidence supporting radical prostatectomy for selected patients.
