subgroups (HR 1.7, 95% CI 1.0-2.8, p Z 0.033). In high-risk subgroups, 5year BCR-free survival rates of patients with PSA level < 0.50 and 0.50 ng/ml at BCR were 45% (95% CI, 34e55) and 28% (95% CI, 14e44), respectively (p Z 0.033). Early SRT did not improve outcomes significantly in low-and intermediate-risk groups (p Z 0.92 and 0.85, respectively). Conclusion: This study suggested that early SRT is beneficial only for selected high-risk subgroups of patients affected by BCR after RP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
