关于食管癌的 TNM 分类,我们介绍一种按照日本食管癌规约修订之新方法。新的肿瘤(T)分类是基于肿瘤侵累食管的深度;新的淋巴(N)分类不仅包括纵隔淋巴结,也包括胃周围淋巴结群的转移。我们收集了日本自1969～1978年胸段食管癌3,211例的资料,按照现行的和新的食管癌 TNM 分类法进行分析。结果表明,新的分类法可以更好地表明生存率的关系。新的 T 与 N 通过临床检查较易得到确
Regarding the TNM classification of esophageal cancer, we introduce a new method that has been revised according to the Japanese esophageal cancer protocol. The new tumor (T) classification is based on the depth of invasion of the esophagus by the tumor; the new lymphoid (N) classification includes not only mediastinal lymph nodes but also metastases around the gastric lymph nodes. We collected data on 3,211 cases of thoracic esophageal cancer in Japan from 1969 to 1978 and analyzed them according to the current and new TNM classification of esophageal cancer. The results show that the new classification method can better demonstrate the relationship between survival rates. The new T and N are easier to confirm by clinical examination
