Accurate TNM staging plays a pivotal role in cancer management and research. The TNM staging system for esophageal cancer is frequently viewed with discontent by thoracic surgeons. Yet, the sixth editions of the American Joint Committee on Cancer (AJCC) and the Union Internationale Contre le Cancer (UICC) staging manuals, published in 2002, offered minimal changes in the chapter on esophageal staging.
1,2 The AJCC chapter notes the remarkable epidemiologic shift that has occurred in this disease with a rapid increase in the number of adenocarcinomas of the distal esophagus and gastroesophageal junction. The location of the lymph nodes involved by gastroesophageal junction tumors was added to the section on nodal descriptors, and a lymph node map previously proposed by Casson and colleagues
3 was added to encourage uniform nomenclature of lymph nodes removed at surgery. However, the TNM descriptors and stage classifications were not changed from the previous editions of the staging manuals.
The lack of change in the esophageal staging system frustrates many surgeons who believe that it does not stratify patients appropriately for prognosis. However, a staging system must be evidence-based, prognostically accurate, easy to use, and internationally accepted. The AJCC task . . . [Full Text of this Article]
