Note 1 When primary site code is C160, the cancer will be staged using either the stomach cancer schema or the esophagus schema depending on the distance of the tumor's epicenter into the proximal stomach and whether or not the esophagogastric junction is involved.
Assign the code that best reflects EGJ involvement and the distance of the tumor's epicenter into the proximal stomach.
- Chapter 16 Esophagus and Esophagogastric Junction (see code 2)
Tumor involving the EGJ with epicenter less than 2 cm into proximal stomach - Chapter 17 Stomach (see codes 0, 3, and 9)
No involvement of the EGJ or unknown if involvement of the EGJ AND epicenter at any distance
Note 2 The CAP protocol uses "midpoint" instead of "epicenter."
