Reportability/Histology--Pancreas: Is a diagnosis of insulin-producing (insulinoma) epithelioid neoplasm reportable if made 2021 and later? If so, is the histology coded as 8151/3 per the ICD-O-3.2 Coding Table? See Discussion.
Reportability/Behavior--Ovary: Is adult granulosa cell tumor a reportable malignant tumor if the primary ovarian tumor ruptured intraoperatively, the peritoneum was contaminated, and the patient underwent adjuvant treatment with chemotherapy given the increased risk of recurrence due to intraoperative tumor spill? See Discussion.
Primary Site/Brain and CNS: How is primary site coded when the ICD-O-3 provides a sub-site-associated morphology code and the only information available to code primary site for a particular diagnosis indicates a non-specific/not otherwise specified (NOS) site code? See Discussion.
Reportability/Ambiguous Terminology: When the only source of information states the diagnosis as two terms, one reportable and one non-reportable, separated by a "slash" (/), should we report the case using the reportable term? See Discussion.
Date Therapy Initiated: How would you estimate the date treatment began for a patient who was treated elsewhere and seen only on an outpatient basis at the current facility? See discussion.
Primary Site--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary?
