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.

Distant nodes are coded in CS Mets at DX. Note 2: Regional lymph nodes for any part of the esophagus fall in the range from periesophageal/cervical to the celiac region. Contralateral and bilateral cervical, supraclavicular, and mediastinal lymph nodes are included. Note 3: Celiac nodes are coded in CS Lymph Nodes for lower thoracic (abdominal) esophagus; they are coded in CS Mets at DX for cervical and intrathoracic (upper and middle) esophagus. Cervical nodes, NOS are coded in CS Lymph Nodes for cervical esophagus; they are coded in CS Mets at DX for upper and lower thoracic (abdominal) esophagus. Note 4: Lymph node stations/groups are listed in parentheses when applicable. See Figure 10.3 in the AJCC 7th Edition Staging Manual or Handbook for illustrations. Note 5: Nodal metastasis is very rare in gastrointestinal stromal tumors (GISTs), and surgeons generally agree that nodal dissection is not indicated. In the absence of information on regional lymph node status, N0 is appropriate; code 999 is mapped to N0 accordingly.
