Stomach cancer: a study of 117 consecutive resected cases and results of R2-R3 gastrectomy.

In a consecutive series of 175 patients with gastric carcinoma, 66.8% underwent gastric resection: 74 total gastrectomies with R3 lymphadenectomy and 43 distal subtotal gastrectomies with R2 lymphadenectomy were performed. 73% (86 cases) of resective procedures proved to be "absolute curative" according to Japanese criteria (JRSGC). Nodal involvement was present in 62 out of 117 resected patients (52.9%): 29.9% N1, 9.4% N2, 13.6% N3; a significant relationship (p = 0.012) between depth of invasion of the gastric wall and lymph node metastases was revealed. The hospital mortality after R2-R3 gastrectomy was 4.2%, major surgical complications occurred in 6.8% of cases. The actuarial 5-year survival after curative resection was 59%. The results suggest that extended lymphadenectomy (R2-R3 gastrectomy) is justified in the surgical treatment of gastric cancer; this procedure can be safely performed and permits "absolute curative" resections in a remarkable percentage of cases.
