Collaborative Stage

Collaborative Stage for TNM 7 - Revised 05/24/2011 [ 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: The three layers of the mucosa (epithelium, lamina propria, and muscularis mucosae) may be called the m1, m2, and m3 layers. The submucosa may be described as having inner, middle, and outer thirds called sm1, sm2, and sm3.
Note 3: For this schema, AJCC defines Tis as high-grade dysplasia, in which they include "all non-invasive neoplastic epithelium that was formerly called carcinoma in situ". Cancers stated to be noninvasive or in situ are classified as Tis. High grade dysplasia is generally not reportable in cancer registries; but if a registry does collect high grade dysplasia, code 000 should be used.
