Inquiry Details

2014 SEER Manual
Question:
Primary Site/In Situ: How is primary site coded for an in situ carcinoma arising in a mucinous cystadenoma with ovarian stroma (focal) located in the right lobe of the liver? See discussion.
Discussion:
The SEER Coding and Staging Manual instructs one to code the primary site to the location where the tumor originated, in this case the liver. However, there is no CS Extension code for in situ tumors found in the CS Manual Liver Schema.
Answer:
Based on the information provided, the primary site is liver. Submit the CS question to the CoC CAnswer Forum, http://cancerbulletin.facs.org/forums/content.php
