ABSTRACT
INTRODUCTION:
In order to identify the impact of local treatment on overall survival (OS) and cancer-specific survival(CSS) in men with mPCa. MATERIALS ANDMETHODS:
Men with mPCa undergoing local treatment by radical prostatectomy (RP), radiotherapy (RT) including beam radiation and brachytherapy or no local treatment identified from Surveillance, Epidemiology, and End Results (SEER) database (2010-2015). To evaluate local therapy impact on OS and CSS in relation to baseline characteristics, univariate and multivariable Cox regression analysis was used to predict the prognostic value of local therapy in OS and CSS.RESULTS:
A total of 902 (25.8%) patients received local treatment and 2598 (74.2%) patients did not receive local treatment in this study. The Kaplan-Meier curves showed that there was significant difference in OS between patients underwent local treatment and patients without local treatment (P = .013) but not in CSS (P = .068). While multivariate Cox regression analysis showed that local treatment may not significantly improve OS(P = .724). In subgroup analysis, Among patients with prostate-specific antigent (PSA)<10ng/ml, local treatment could significantly improve OS and CSS (all P < .05). Multivariate Cox regression analysis showed that local treatment could be used as an independent prognostic factor to improve OS in mPCa patients with PSA<10ng/ml (P = .031). Another multivariate Cox regression analysis demonstrated that patients with mPCa undergoing RP had better OS and CSS (all P < .05).CONCLUSIONS:
Our results showed that local salvage therapy did not seem to be an independent prognostic factor in all mPCa patients, but we found that local therapy can show a better prognosis in patients with lower PSA levels. Compared with RT, patients who had experienced RP may have better prognosis. We still need prospective research to further study the application value of local treatment in mPCa patients.Palavras-chave
