Vaginal cuff length during radical hysterectomy is a prognostic factor for stage IB-IIA cervical cancer: a retrospective study.

Abstract

PurposeThe aim of this study was to investigate the impact of vaginal cuff length (VCL) resected during radical hysterectomy (RH) on the long-term survival outcomes of patients with cervical cancer (International Federation of Gynecology and Obstetrics [FIGO] stage IB–IIA) and to explore whether VCL is a prognostic factor for cervical cancer.MethodsA total of 435 eligible patients with stage IB and IIA cervical cancer who underwent RH in Zhongnan Hospital of Wuhan University (Wuhan, People’s Republic of China) from January 2007 to February 2017 were retrospectively analyzed. These patients were divided into two groups (VCL ≤2.0 cm and >2.0 cm) for further analysis according to the VCL during RH. The Kaplan–Meier method was adopted to calculate the survival rates. Univariate and multivariate Cox regression models were used to analyze independent prognosis factors for survival.ResultsOf the 435 identified patients, 196 had VCL ≤2.0 cm and 239 had VCL >2.0 cm after RH. The 5-year disease-free survival (DFS) for the group who had VCL ≤2.0 cm vs the group who had VCL >2.0 cm was 68.1% vs 87.5% (P<0.001). Correspondingly, the overall survival (OS) for the two groups was 71.4% vs 89.2% (P<0.001). More interestingly, the VCL was significantly associated with the 5-year local recurrence rate, but not associated with the distant metastasis rate. In addition to the VCL, FIGO stage and lymph node involvement were also identified as significant prognostic factors for cervical cancer.ConclusionResection of VCL >2.0 cm in RH has a more favorable long-term outcome than VCL ≤2.0 cm among patients with cervical cancer (FIGO stage IB–IIA); shorter VCL resection was significantly associated with local recurrence, DFS, and OS; thus, it can be considered as a prognostic factor for cervical cancer.
