Question:
Reportability/EOD Primary Tumor--Ovary: Bilateral ovary shows gonadoblastoma with germ cell neoplasia in situ (9064/2). Pathology report clearly states in situ. Is this case reportable?
If this case is reportable, how would you code Extent of Disease (EOD) Primary Tumor and SEER Summary Stage (SS)? In situ code 000 for primary tumor and code 0 for SS 2018 is not given as an option.
Discussion:
Answer:
Report germ cell neoplasia in situ (9064/2). Assign 999 for EOD Primary Tumor and assign 9 for SS2018.
This particular histology is in the Soft Tissue Abdomen and Thoracic schema where EOD PT 000 and SS2018 0 are not available. This histology will be moved to the Ovary schema after redefining certain schemas and thus making the more accurate choices for EOD and SS2018 available. The schema redefine is planned for 2024 implementation.
