Collaborative Stage

Collaborative Stage for TNM 7 - Revised 01/26/2010 [ Schema ]

Esophagus

CS Extension

Note 1: Ignore intraluminal extension to adjacent segment(s) of esophagus or to cardia of stomach and code depth of invasion or extra-esophageal spread as indicated.
Note 2: T4 has been subclassified into T4a and T4b in the 7th Edition.
Note 3: For this site, AJCC defines Tis as High grade dysplasia, in which they Include "all non-invasive neoplastic epithelium that was previously called carcinoma in situ. Cancers stated to be non-invasive or in situ are classified as Tis." High grade dysplasia is generally not reportable in cancer registries, but if a registry does collect it, code 000 should be used.
