Cancers whose epicenter is more than 2 cm distal from the EGJ, even if the EGJ is involved, will be staged using the stomach cancer TNM and stage groupings. **Note 4:** *Schema Discriminator 1: EsophagusGEJunction (EGJ)/Stomach* is used to discriminate between EsophagusGEJunction and Stomach which are coded to ICD-O-3 code C160. **Note 5:** This schema is for adenocarcinomas and other histologies only. Squamous cell histologies are collected in the Esophagus (including GE junction) Squamous schema.Data Items
