STUDY ON SURGICAL TREATMENT FOR ADVANCED GASTRIC CANCER

This study included 1175 patients who underwent laparotomy for advanced gastric cancer at Aichi Cancer Center Hospital between 1965 and 1972. The five-year survival rate for 613 patients who had undergone curative gastrectomy was 51.2%. A non-curative gastrectomy was performed on 252 patients and 10.3% of them survived for 5 years. Patients who underwent gastrojejunostomy, exploratory laparotomy and gastrostomy or jejunostomy numbered 100, 173 and 22 respectively.
Survival rates for patients undergoing non-curative gastrectomy were analysed. Of 252 patients having non-curative gastrectomy, the five-year survival rate of 60 patients with distant lymph node metastasis was 13.3% and that of 51 patients with cancer infiltration to the cut edge of the stomach was 11.8％. The five-year survival rates of 14 patients with liver metastasis and 106 with peritoneal dissemination were 14.3％ and 7.5％ respectively.
In patients with relatively differentiated cancer, liver metastasis showed the highest incidence; in cases with less differentiated cancer, peritoneal dissemination was the most frequent among metastases. Mitomycin C as surgical adjuvant chemotherapy was effective in preventing liver metastasis for patients with relatively differentiated cancer.
