Abstract

Extracapsular spread (ECS) of metastatic lymph node in oral cancer is the most significant prognostic predictor of poor treatment outcome. However, only a few reports on prognostic indicators in ECS positive cases have been published. The purpose of this study was to determine the prognostic factors of oral squamous cell carcinoma (OSCC) with ECS in metastatic lymph nodes. In this study, the cases of 77 patients with primary OSCC, who attended our hospital from 2008 to 2013 and had at least one pathologically metastatic node with ECS, were reviewed. Patients with primary recurrence during follow up were excluded from the present study. Univariate analyses revealed that many kinds of cervical metastatic factor, including number of ECS positive lymph nodes, were significantly associated with recurrence and poor outcome. Moreover, multivariate analyses indicated that the number of ECS positive metastatic lymph nodes is the only significant factor predicting regional recurrence and poor outcome. In conclusion, the number of ECS positive lymph nodes is the most important prognostic indicator for OSCC with ECS in metastatic lymph nodes. Thus, classification of ECS status using the number of ECS positive lymph nodes may be useful for further prediction of poorer prognosis in OSCC cases. However, standardization of ECS diagnosis and a larger multicenter prospective study for refining the present finding are required.
