Primary Site/Histology--Urinary: Is a urethral lesion showing intraductal carcinoma of the prostate reportable? What is the primary site and histology code? See discussion.

Primary site/MP/H Rules/Histology: What is the appropriate site and histology code for a tumor described as a "Large mass In suprasellar cistern encroaching into sphenoid & ethmoid sinuses", with the pathology described as "INI-1 deficient sinonasal undifferentiated carcinoma"? Of note, this patient has a history of a pituitary adenoma, resected overseas a few months prior to this diagnosis.

First course treatment: Is subsequent treatment with R-ICE first course or second course therapy if the patient underwent ABVD x2 cycles and subsequent imaging showed no response to treatment and evidence of progression [new adenopathy] for a lymphoma case? See Discussion.

Reportability--Kidney: Is the donor or the recipient the reportable patient when a cyst removed from a pre-transplanted kidney is determined to be cancerous? See Discussion.

Reportability--Brain and CNS: Why has reportability changed for "intradural extramedullary schwannomas"? Are all "spinal" schwannomas reportable or only those stated to be "intradural"? See Discussion.

Solid Tumor Rules (2018)/Multiple primaries--Bladder: Does Rule M11 in the 04/2019 Solid Tumor Rules Urinary update apply to synchronous/simultaneous tumors only or to multiple tumors with any timing? See Discussion.

Multiple Primaries (Pre-2007)--Thyroid: Does the rule in the 3rd Edition of the SEER Program Code Manual apply to cases diagnosed before 1998 that states if there are two separate carcinomas in the thyroid, one papillary and the other follicular, it is one primary and coded to the combination code 8340/3 [Papillary and follicular carcinoma]? See discussion.

Solid Tumor Rules/Histology--Other Sites: Should an additional Note be added to Other Sites Solid Tumor Rules, Rule H12, to indicate that if the diagnosis is an NOS histology in a polyp, continue on through the rules or should Other Sites Rule H13 be moved ahead of Rule H12 to capture this specific histology? See Discussion.

First Course Treatment: If the patient receives no treatment at the time of diagnosis (either because it is not recommended or because the patient refused treatment at that time) but treatment is later instituted after disease progression, should this treatment be coded as part of the first course of treatment?
