Localized prostate cancer in older patients: Radical prostatectomy or radiotherapy versus observation
Journal of Geriatric Oncology(2024)
Abstract
Introduction
This study evaluates the effects of radical prostatectomy (RP) or irradiation on overall survival (OS) and prostate cancer-specific mortality (PCSM) in older patients with localized prostate cancer (PC).
Materials and Methods
We conducted a comprehensive literature review across PubMed, EMBASE, and the Cochrane Library from inception up to December 2023 to identify studies comparing the outcomes of surgery or radiotherapy (RT) versus observation in patients aged 65 and older with localized PC. We pooled hazard ratios (HRs) for OS and PCSM using random-effects models.
Results
Thirteen studies involving 284,066 patients were analyzed. Three were large randomized trials (RCTs) and 10 were retrospective studies. Overall survival with surgery was greater in observational studies (HR = 0.52, 95% confidence interval [CI] 0.47–0.59; P < 0.001) than in RCTs (HR = 0.84, 95%CI 0.72–0.98; P = 0.03). Data on PCSM from seven studies also indicated a significant benefit for RP in RCTs (HR = 0.47; 95% CI: 0.3–0.73; P < 0.001) and observational studies (HR = 0.41, 95%CI 0.27–0.62; P < 0.001). Both analyses presented high heterogeneity (I2 = 90%, P < 0.001 and I2 = 65%, P = 0.01). An analysis of patients receiving RT indicated a significant, albeit smaller, OS (n = 7 studies) and PCSM (n = 5 studies) advantage (HR = 0.69; 95% CI: 0.59–0.79; P < 0.001; and HR = 0.60; 95% CI 0.44–0.82; P = 0.001) compared to observation (1 RCT and 8 observational studies).
Discussion
The evidence suggests that patients with PC might consider opting for surgery as the main treatment option or, alternatively, for RT, as an alternative to observation, based on their individual medical history, life expectancy, and preferences.
