Notes

8970: C220 (all ages) **Note 1:** The following sources were 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) * [Children’s Oncology Group - Newly Diagnosed with Hepatoblastoma or Hepatocellular Carcinoma](https://childrensoncologygroup.org/newly-diagnosed-with-hepatoblastoma-or-hepatocellular-carcinoma-) * [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:** For Hepatoblastoma tumors, there are three different staging systems collected * Toronto Staging is based on the absence or presence of mets and is collected in Pediatric Mets * The Children’s Oncology Group (COG) for liver staging is used. * Per this staging system, anything involved outside the liver is Stage IV. This is different than other staging used in the US that has adjacent organs not being a Stage IV * Pediatric Primary Tumor, Pediatric Regional Nodes and Pediatric Mets are used to derive the stage group * Pretext is collected as a SSDI and is based on clinical staging only
