Notes
C160 Cardia, esophagogastric junction (EGJ) C161 Fundus of stomach, proximal 5 centimeters (cm) only C162 Body of stomach, proximal 5 cm only **Note 1:** This schema is based on the UICC chapter *Oesophagus including Oesophagogastric Junction,* pages 66-72. * Primary sites C161 and C162 are not listed in this chapter of the UICC manual; however, they are included in this schema and TNM staged if appropriate histology criteria are met * **Site-Specific Factor 25, Schema Discriminator: EsophagusGEJunction (EGJ)/Stomach** is used to discriminate between esophagusGEjunction and stomach which are coded to ICD-O-3 codes C160-C162. **Note 2:** The cardia/EGJ and the proximal 5 cm of the fundus and body of the stomach have been removed from the Stomach chapter and added to the Esophagus chapter effective with TNM 7th Edition. Due to differences between the schemas for Esophagus and Stomach, a new schema was created in 2010 accommodate these changes. Since primary site codes C161 (fundus of stomach) and C162 (body of stomach) can be assigned to either schema, EsophagusGEJunction or Stomach, a schema discriminator field is needed for the staging algorithm to determine which schema to select. In TNM 7th Edition, cancers with a midpoint in the lower thoracic esophagus, in the EGJ, or within the proximal 5 cm of the stomach (cardia) and extending into the EGJ or esophagus, are staged similarly to cancers of the esophagus. All other cancers with a midpoint in the stomach greater than 5 cm distal to the EGJ, or those within 5 cm of the EGJ but not extending into the EGJ or esophagus, are staged using the gastric cancer staging system. **Note 3:** Effective with TNM 7th Edition * Histologic grade is required for stage grouping * There are separate stage groupings for squamous cell carcinoma and adenocarcinoma. Since squamous cell carcinoma typically has a poorer prognosis than adenocarcinoma, a tumor of mixed histopathologic type or a type that is not otherwise specified should be classified as squamous cell carcinoma **Note 4:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Esophagus* chapter on page 74 of the [SS2000 on-line manual](http://seer.cancer.gov/tools/ssm/SSSM2000-122012.pdf#page=74).Main Data Items
