Risk Factors and Survival Outcomes for Patients With Anastomotic Leakage After Surgery for Head and Neck Squamous Cell Carcinoma

Abstract

ObjectivesThis study evaluated the risk factors for anastomotic leakage (AL) and survival outcomes in patients with head and neck squamous cell carcinoma (HNSCC).MethodsPatients with HNSCC who underwent surgery carrying potential AL from 2003 through 2009 were included in this study. Univariate and multivariate analyses were performed and patient survival was calculated by the Kaplan-Meier method.ResultsOf 232 eligible patients, 25 (10.8%) developed AL. Univariate analyses revealed that primary tumor site, salvage surgery, perineural invasion, radiotherapy, chemotherapy, and blood transfusion were significantly associated with the occurrence of AL (P0.1).ConclusionPatients who received salvage surgery and blood transfusion may require careful surveillance for development of AL, which has a tendency toward decreased survival.
