5-year overall survival analysis of each group divided according to venous invasion. The cumulative 5-year overall survival (OS) rate of the total 97 patients with Stage III gastric cancer was 42.6%. The patients with venous invasion exhibited a significantly poorer OS than patients with gastric cancer of other histological types (5-year OS, 33.7% vs. 50.4%, P = 0.027)
