Solid Tumor Rules (2018)/Histology--Kidney: What is the histology code for succinate dehydrogenase-deficient renal cell carcinoma (SDHD)? See Discussion.

First Course Treatment/Neoadjuvant Therapy--Breast: When are pre-operative therapies given as part of a clinical trial coded as neoadjuvant treatment versus limited systemic exposure in the Neoadjuvant Therapy data item? See Discussion. 

2021 SEER Manual/Primary Site--Ovary, Fallopian Tube: What information takes precedence for coding the primary site in cases with high grade serous carcinoma that are clinically called ovarian but on pathology, the pathologist calls the primary site fallopian tube and the gynecology oncology/managing phsyician continues to call the cases ovarian. Both the ovary and tube are involved. Sometimes also referred to as "tubo-ovarian."

Reportability/Histology--Pancreas:  Is well-differentiated neuroendocrine tumor (M8240/3) as stated on a pathology report reportable or can the clinical information be used as an adjunct to the path report, which further states the specific type of neuroendocrine tumor is an Insulinoma, therefore, NOT reportable (M8151/0)? See discussion.

MP/H Rules--Histology: How is histology coded when a metastatic site is biopsy positive for adenocarcinoma, but the physician clinically states this is cholangiocarcinoma? See discussion.

Update to the Current Manual/Tumor Size Summary—Neoadjuvant Treatment: Would you clarify instructions in the 2024 SEER Program Coding and Staging Manual (SPCSM) for Tumor Size Summary when a patient receives neoadjuvant treatment? There seems to be a conflict with the STORE Manual. See Discussion.

When coding the Covid testing results, does SEER have any guidance on whether or not at home tests fall within reportability? For instance, if a medical provider says pt tested positive on an at home test, do we record that?

Histology--Lung:  Is it acceptable to code histology as 8042/3 for a 2020 lung primary when the pathology report states only "oat cell carcinoma?" See Discussion.
