title: Pathologic features and long-term results in early gastric cancer: report of 116 cases 8-13 years after surgery.
abstract: One hundred sixteen patients who underwent surgery for early gastric cancer (EGC) at Careggi General Hospital in Florence between 1987 and 1992 were studied with regard to clinicopathologic features, incidence, and recurrence of the disease. The overall 5-year cumulative survival rate was 87.5%, and the disease-specific 5-year survival rate was 88.2%. EGC was limited to the mucosa in 43 patients (37%), while it infiltrated the submucosa in 73 others (63%). At the time of surgery, 9.5% of patients were found to have lymph node metastasis, always concomitant with submucosal invasion. There was 1 postoperative death (0.8%); 16 patients (13.7%) died of tumor recurrence, and 20 (17.2%) died of unrelated causes. Analysis of recurrence showed an intestinal histotype in 13 patients (81.2%), submucosal infiltration in 14 patients (87.5%), a Pen-A growth pattern in 8 patients (50%), and lymph node involvement in 3 patients (18.7%). The Cox proportional hazard model indicated that age and depth of wall invasion were statistically significant. The best predictor of survival appears to be the depth of invasion within the gastric wall. The claim by several investigators that prognosis for EGC is also associated with the presence of lymph node involvement is not supported by the present study. The postoperative 5-year survival rate in node-negative patients was 88.8% compared to 81.8% in node-positive patients (p = 0.296).
