    Abstract:
    We retrospectively examined the extent of invasion of gastric cancer with duodenal involvement in order to design pertinent surgical procedures that may lead to a better prognosis. Examinations were made on excised tissues from 650 patients who underwent gastrectomy for adenocarcinoma in the gastric antrum. In 95 patients, the cancer cells extended to beyond the pyloric ring. Spread into the duodenum was limited to within 2 cm in 76% of the patients and to within 3 cm in 81%. In addition to high rates of metastasis in group 1 and 2 lymph nodes, some group 3 lymph nodes also were involved, and more frequently so in cases with duodenal invasion than in those without such invasion (P < 0.01). The 5-year survival rate for patients with duodenal invasion was 35.4% when a curative resection was done. For patients with advanced adenocarcinoma with duodenal invasion, gastrectomy with resection of 3-4 cm of the duodenum and dissection of group 1, 2, and 3 lymph nodes were recommended.
