The new 8th edition of the TNM classification system for esophageal and cardia or esophagogastric junction cancer provides important innovations in the TNM stages. Two classifications are presented, updated by stages, clinical (cTNM) and pathological (pTNM) methods, together with another pathological classification applicable to cases receiving neoadjuvant treatment (ypTNM). There is a notable increase in complexity compared to previous versions, but it is still early to determine whether the current modifications will result in a clear improvement in the prognostic discrimination of survival among the patient groups (which is their main objective), although the initial expectations are favorable.
食管癌、贲门癌或食管胃交界癌的新版TNM分类系统第8版在TNM分期方面有重要创新。给出了两种分类，按阶段更新，包括临床（cTNM）和病理（pTNM）方法，还有另一种适用于接受新辅助治疗病例的病理分类（ypTNM）。与以前版本相比，复杂性显著增加，但目前尚难以确定当前的修改是否会明显改善患者组间生存预后的判别（这是其主要目标），尽管初步预期是乐观的。
