Notes

**See table above for primary sites and histologies for this schema** **Note 1:** **Sources used in the development of this schema** * [Toronto Childhood Cancer Stage Guidelines, Version 2, May 2022](https://cancerqld.blob.core.windows.net/content/docs/childhood-cancer-staging-for-population-registries.pdf) * [SEER Extent of Disease (EOD) 2018: Codes and Coding Instructions](https://seer.cancer.gov/tools/staging/eod/2018_Extent_of_Disease_General_Instructions.pdf) * [Summary Stage 2018 - SEER (cancer.gov)](https://seer.cancer.gov/tools/ssm/) **Note 2:** **Criteria for Toronto Staging** * For Medulloblastoma, Toronto Staging is based on the presence or absence of mets based on the *Chang M* definition for metastases within the CNS at diagnosis and is collected in Pediatric Mets. * Pediatric Primary Tumor is collected for surveillance purposes **Note 3:** **Age range required** * Required for ALL AGES due to the nature of this tumor * Medulloepitheliomas, although more common in the pediatric age range, affect all ages and ALL AGES are treated with the pediatric protocol, necessitating collection regardless of age.
