Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/12/2010 [ Schema ]

GISTEsophagus

CS Extension

Note 1: AJCC does not include a Tis category for gastrointestinal stromal tumors (GIST). Any case with a CS Extension code of 000 is mapped to TX for AJCC 7 stage and in situ Summary Stage.
Note 2: 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 3: The assignment of T categories for gastrointestinal stromal tumors (GISTs) is based on tumor size. A physician's statement of the T category may be used to code CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently: for example the record may document size but not extension, other than the physician's statement of the T category. Use codes 170, 210, 250, and 270 as appropriate to code CS Extension based on a statement of T when no other extension information is available.
