[Multicenter retrospective study of 3,024 patients operated on for stomach cancer in Italy. Epidemiology, surgical treatment and survival].

This study presents the results achieved in 2,000 patients who underwent gastric resection and who had been selected from amongst 3,074 cases of gastric neoplasia included in the Retrospective Study of Carcinoma of the Stomach, carried out by the "Italian Stomach Cancer Group" of the Association of Italian Hospital Surgeons (ACOI). In terms of the UICC TNM classification, these patients consisted of 234 stage I patients, 494 stage II patients 1,011 stage III patients and 261 stage IV patients. The overall operative mortality was 7.1 percent. This was lower after subtotal distal resection. The long-term survival tended to fall in proportion with the stage of the illness, whereas the degree of the exeresis did not appear to have any impact. The overall survival at 5 years in the patients who survived the operation was 45%, that following distal resection was 54% and that after total gastrectomy was 33%. The survival rate in terms of the stage ranged from 86% for Early Gastric Cancers to 28% for the patients who underwent surgery at stage III i.e. when they had metastatic lymph nodes.
