Clinicopathologic evaluation of recurrence in early gastric cancer.

Five hundred ninety-two patients with early gastric cancer underwent surgical resection from 1970 to 1986 in our hospital, and 13 died from a recurrence of their disease. A careful analysis of these 13 patients suggests that carcinomas which invaded to the submucosa tend to recur more often than those confined to the mucosa. Well differentiated and papillary adenocarcinomas characterized by protruded or elevated lesions tend to recur earlier than poorly differentiated or signet-ring cell carcinomas characterized by depressed or excavated lesions. However, both types recurred from hematogenous metastases, with the liver being the most common site. Therefore, the macroscopic and histological features presently used to characterize early gastric cancer do not provide sufficient information to accurately predict which patients are at most risk for recurrence.
