    Abstract:
    We retrospectively examined clinicopathologic features of gastric cancer with duodenal invasion to clarify the effect of surgical treatment that include pancreaticoduodenectomy (PD). Among 2504 patients with gastric cancer, 69 (2.8%) who had gastric cancer and duodenal invasion resected by surgical treatment were investigated. The mode of the duodenal invasion was grouped into three categories: mucosal type, submucosal type, and nodal type. Mucosal type is invasion of the duodenal mucosal layer, submucosal type is invasion of the submucosal layer or deeper, and nodal type is invasion from nodal metastatic lesions around the pancreatic head. The 5-year survival rates of curative PD and curative gastrectomy were 37.3% and 33.8%, respectively. Despite the incidence of adjacent tissue infiltration and significantly higher duodenal invasion average length in cases with PD than in cases with gastrectomy, there was no significant difference in the survival curves. However, the prognoses of the cases with nodal-type invasion were significantly poorer, and all these patients died within 2 years, regardless of whether curative PD had been performed. Curative PD improves the prognosis of cases with long duodenal invasion or pancreas infiltration except for nodal-type duodenal invasion.
