食管癌的精准诊断和分期是构建精准个体化最佳治疗方案的前提和依据。国际TNM分期是目前世界上普遍采用的肿瘤分期标准。为提高分期的准确性，经不定期的修正、更新，尚在不断探索和完善，期望具有更高特异性和准确率的定期方法和标准是今后TNM分期的发展趋势。本文对我国食管癌分期的研究现状和进展进行综述。

The precision diagnosis and staging of esophageal cancer is the premise and basis for the construction of precision individualized optimal treatment scheme. The international TNM staging is widely used staging standard in the world. In order to improve the accuracy of TNM staging, it is still in constant exploration and improvement after irregular revises and updates. It is the development trend of TNM staging in the future to expect the staging methods and standards with higher specificity and accuracy. In this paper, the research status and progress of esophageal cancer staging in China were reviewed.
