[Surgery for gastric carcinoma in patients with high risk of peritoneal metastases]

Survival in 242 cases of lymph dissection (D2) and 319 patients with (D1) operated on for gastric cancer was compared. D2 lymph dissection was not followed by higher survival rates in dealing with such gastric malignancies involving high risk of peritoneal metastases as signet ring cell, undifferentiated cell, diffuse-infiltrative, Borrmann type IV gastric cancer and complete involvement of the stomach. When D2 lymphoadenectomy was carried out for gastric adenocarcinoma, generally known to be rarely accompanied by peritoneal metastases, the end results were much better, even in cases of serosal invasion.
