On multivariate analysis, CT was not a significant factor associated with improved PFS (hazard ratio [HR], 1.37; 95% confidence interval [CI], 0.69-2.71; P = 0.37) or OS (HR, 0.58; 95% CI, 0.24-1.38; P = 0.22), whereas RT was associated with improved PFS (HR, 0.51; 95% CI, 0.29-0.90; P = 0.02) and OS (HR, 0.19; 95% CI, 0.09-0.42; P < 0.001).</p><p><strong>Conclusions: </strong>The high rate of upstaging after surgery highlights the importance of lymph node assessment. The high rate of distant recurrence questions the effectiveness of current CT regimens and warrants the development of novel systemic approaches. The role of adjuvant RT deserves further study.</p>","PeriodicalId":13983,"journal":{"name":"International Journal of Gynecologic Cancer","volume":"5 1","pages":"69-76"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79668881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
