Pediatric Primary Tumor
Notes
**Note 1:** Evaluation of primary tumor is based on several factors
* Surgically resected WITH or WITHOUT neoadjuvant therapy and tumor(s) confined to the liver with **negative/unknown** margins
- One lobe involved (see code 150)
- More than one lobe involved (see code 250)
* Surgically resected WITH or WITHOUT neoadjuvant therapy and tumor(s) confined to the liver with **positive** margins (codes 175 and 275)
- One lobe involved (see code 175)
- More than one lobe involved (see code 275)
* Partial surgical resection WITH or WITHOUT neoadjuvant therapy, or unresectable and tumor(s) confined to the liver (code 350)
**Note 2:** Direct or contiguous extension to an adjacent structure is collected in Pediatric Mets.
* If the only information available is extension to an adjacent site, code Pediatric Primary Tumor 999.
* Extension to the following are collected in EOD mets
* Diaphragm
* Extrahepatic bile duct(s)
* Extrahepatic blood vessel(s) (hepatic artery, portal vein, vena cava)
* Ligament(s) (coronary, falciform, hepatoduodenal, hepatogastric, round (of liver), trangular)
* Gallbladder
* Major vascular invasion
* Omentum (lesser and greater)
* Pancreas
* Peritoneum, NOS
* Pleura
* Stomach
