The October-November issue of Diseases of the Esophagus contains the first three articles dedicated to the analysis of the data gathered by the Worldwide Esophageal Cancer Collaboration (WECC) lead by Prof. Thomas Rice, that will form the basis for the new (8th) edition of the UICC- AJC TNM classification.
Data from more than 22,000 patients with staged esophageal cancer from 33 institutions in six continents were analyzed. Each institution submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all causes mortalities from the first management decision. Clinical data, pathological data, and pathological data in patients that received neoadjuvant chemo or chemoradiotherapy were separately addressed. One of the most relevant finding of this analysis is the need for a separate classification for pathological stage in patients operated with or without neoadjuvant therapy.
