Question:
Primary Site--Stomach: How do I code the primary site when the operative report and pathology report state that the tumor site is incisura of the stomach?
Discussion:
Answer:
Assign C163. Incisura, incisura angularis, gastric angular notch, angular incisure of stomach all refer to the sharp angular depression in the lesser curvature of the stomach at the junction of the body with the pyloric canal. See Gastric angular notch in #12 on page 76 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf. See also the SEER training website, #12 on the illustration corresponds to the angular notch, http://training.seer.cancer.gov/ugi/anatomy/stomach.html. We will correct the key for this illustration.
