[The study of lymph nodes metastasis and staging of carcinoma of the gastric cardia by computer].
A total of 605 cases of the carcinoma of gastric cardia resected were analysed univariantly using program of analysis for risk states and survival analysis by life table method on IBM-PC computer. The significance of lymph nodes metastasis in different situations concerning prognosis was evaluated. Our results suggest that the lymph nodes with metastasis at the lower part of esophagus should be grouped as N 1 in the TNM staging system for carcinoma of the gastric cardia. We propose a new staging method, using number of lymph nodes metastasis and degree of tumorous infiltration to the adjacent organs as main indices, for the advanced carcinoma of the gastric cardia clinically and pathologically.
