[Evaluation of the new international TNM staging system for carcinoma of the esophagus as compared with the Chinese trial clinicopathological staging system--an analysis of 224 cases].
A further comparison was made between the new international TNM staging system (1987) and the Chinese trial clinicopathological Staging system (1976) in 224 cases of intrathoracic esophageal carcinoma treated by surgical resection at the Department of Thoracic Surgery of Cancer Hospital, Chinese Academy of Medical Sciences between 1983.11-1986.5. Our results showed that the new international TNM staging classification is superior to that used in China with regard to the stratification of IIA, IIB and III stage grouping. The new stage grouping reflected fairly well the grade of disease extent. The new staging has greater predictive value for evaluating the incidence of possible Ro resections and especially permits a considerably improved prognostic assessment. Five-year survival rates of patients with radical resection were 80%, 47.3%, 22.2%, 16.1% and 0% in stages I, IIA, IIB, III and IV, respectively. It is suggested that the new TNM stage grouping should be adopted in our country. Some points were discussed in connection with the use of the new TNM stage grouping.
