Kaplan-Meier curves of overall survival (OS) were compared in patients with TNM stage II-III and IV a . For patients with stage II–III, the 1-, 3-, and 5-year OS were 78.6%, 49.4%, and 39.9%, respectively, versus 68.3%, 41.0%, and 15.4% for IVa patients, respectively, however, no statistically significant difference was observed in our limited sample size (p=0.671).
