- Objectives. This study evaluated the risk factors for anastomotic leakage (AL) and survival outcomes in patients with head and neck squamous cell carcinoma (HNSCC).
Methods. Patients 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.
Results. Of 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 (P<0.05). Independent risk factors for AL were salvage surgery and blood transfusion (P<0.01). On univariate analysis, AL was significantly associated with overall (OS) and disease-free survivals (DFS; P<0.05) but not with decreased locoregional control (LRC) rate (P=0.07). The 5-year DFS rate was significantly different between the non-leakage and leakage groups (70.9% vs. 27.7%, P<0.001). Multivariate analysis showed, however, that AL was not an independent variable of LRC, DFS, or OS (P>0.1).
Conclusion. Patients who received salvage surgery and blood transfusion may require careful surveillance for development of AL, which has a tendency toward decreased survival.
