Abstract
PurposeData from randomized controlled trials in high-grade endometrial cancer are scarce due to its low prevalence. Therefore, guideline recommendations in this cancer subtype rely on relatively few randomized trials and data from retrospective studies. The aim of this study was to evaluate the benefits from guideline-concordant therapy in high-grade endometrial cancer in a real-world patient group.MethodsThe effect of treatment according to German S3 guidelines and the former S2k guideline on overall survival (OS) and recurrence-free survival (RFS) was evaluated in a cohort of 293 high-grade endometrial cancer patients.ResultsTreatment concordant with the S3 guideline significantly improved OS (HR 0.623, CI 0.420–0.923, p = 0.018) and RFS (HR 0.578, CI 0.387–0.863, p = 0.007). Treatment concordant with the S2k guideline did not result in a significantly higher OS (HR 0.783, CI 0.465–1.316, p = 0.335) or RFS (HR 0.741, CI 0.347–1.740, p = 0.242).ConclusionTherapy according to the German S3 guideline improved OS and RFS in univariate as well as multivariate analysis in this cohort of high-grade endometrial cancer patients.
