title: [Problem of the general rules and the TNM classification].

On the other hand, cardiac and cervical lymph node metastases with good prognosis were categorised as M1 and correspond to stage IV, so that the meaning of stage grouping is disappeared each other. A new classification of esophagus carcinoma based on the depth of invasion is proposed by the Esophagus Carcinoma Registration Committee.
