Welcome to the SEER Inquiry System (SINQ). SINQ is a collection of questions that
cancer registrars have had while coding cancer cases. Click Search to look for
specific questions or to select questions for a Report.
MP/H Rules/Multiple primaries--Breast: Regarding rule M6 in the breast MP/H rules, if a patient has a left breast inflammatory carcinoma (ductal with apocrine features on bx), and during work-up, an incidental 1.2 cm lobular carcinoma is discovered in the lateral right breast - localized without any skin involvement - does M6 still apply and this is considered a single primary? The managing physician seems to imply that these are 2 different primaries. However, rule M6 seems to state that inflammatory in either breast makes this a single primary.
Reportability: Given that per the 2012 SEER Manual and SINQ 20120081 VIN II-III is no longer reportable, does this also apply to AIN II-III, VAIN II-III, etc.? Or does this change only affect VIN II-III? See discussion.
MP/H Rules/Multiple primaries: How many primaries are to be abstracted and what rule applies when a patient has a serous carcinoma of the right ovary treated with neoadjuvant chemotherapy followed by a debulking surgery that also revealed a serous tubal intraepithelial carcinoma of the left fallopian tube? See discussion.
MP/H Rules/Multiple Primaries/Recurrence: Can we use the statement of “recurrence” by the pathologist who reviewed all slides to code a single primary if a diagnosis of “squamous cell carcinoma” of the LUL lung is followed three years later by pneumonectomy diagnosis of “adenocarcinoma”? See discussion.
First course treatment/Chemotherapy: If a specific primary site/histology is listed in SEER*Rx for a given drug, are we only allowed to code that drug as treatment for only those identified Primary Sites/Histologies? See discussion.
MP/H Rules/Histology--Colon: The final diagnosis on a path report for a colon specimen says: Carcinoma in situ in a serrated adenoma. Is the correct histology code 8010/2 or 8210/2 or 8213/2?
MP/H Rules/Multiple primaries--Head & Neck: How many primaries does this person have and which MP/H rule did you use to determine your answer? See discussion.
MP/H Rules/Histology--Kidney: What is the correct code for 'cyst associated renal cell carcinoma', 'cystic renal cell carcinoma', and 'cystic renal cell carcinoma, clear cell type'? See discussion.
