| Popis: | Background: There had been a lack of international consensus about the definition of cancer of the gastric cardia until Siewert's classification was approved at a consensus conference during the second International Gastric Cancer Congress held in 1997. Study Design: A review of the prospective gastric cancer database at Aichi Cancer Center from 1983 to 1992 identified 1,913 gastric carcinoma patients who underwent gastrectomy. These patients were classified retrospectively according to the Siewert classification, and 177 patients who fell into one of the three types form the basis of this study. Survival analyses were performed after stratifying patients by clinicopathologic variables. Results: There were 33 patients with type II and 144 with type III, although none had type I, a type frequently observed in the west. No evidence of a change in the frequency of types II or III cancers (approximately 9.3% overall) among gastric carcinoma patients was observed over the 10-year period. Clinical staging of gastric carcinoma by the TNM classification was found to reflect accurately the prognosis of these patients. There were no longterm survivors among the few patients with metastasis to the perigastric nodes of the distal stomach. Conclusions: A striking difference in the distribution of types of adenocarcinoma of the gastroesophageal junction was observed in Japan compared with previously reported western data. A subgroup of carcinoma of the proximal stomach identified as types II and III may not require proximal gastrectomy from the viewpoint of sufficient lymphadenectomy. |
