Yes, code Crooke cell adenoma to 8272/0 pituitary adenoma. According to the WHO classification, it is a variant of adrenocorticotropic hormone (ACTH) producing adenoma (8272/0).

Sirolimus is used to treat GVHD (graft versus host disease) and is not coded as treatment. Even though the sub-category is mTOR inhibitor it does not automatically mean it is a chemotherapeutic agent. Sirolimus affects cells differently than Temsirolimus.  The chemical compounds differ between these drugs. In order to code rapamycin, the drug given must be stated to be either the analog or ester compound.  The SEER*RX database has been corrected and NSCLC/glioblastoma are no longer listed for sirolimus.

 We researched clinical trials and found several that include sirolimus with other chemotherapy drugs for patients who either have received or will be receiving bone marrow transplants for hematologic diseases. In this case it is not coded. There are a few trials that are looking at sirolimus as a treatment for bladder, prostate, nerve sheath tumors, MDS, and AML. For these cases it would be coded in Other (code 2).

Thalamic amyloidoma is not reportable. Amyloidoma (tumoral amyloidosis, amyloid tumor) is a tumor-like deposit of amyloid. It is not neoplastic. Amyloid is a protein derived substance deposited in various clinical settings.

Code microwave tumor ablation as surgery. For lung, assign code 15.

This question was discussed by the technical advisory group – a small group of representatives from each standard setter which meets periodically. The group agreed on this consensus answer.

According to a consensus answer of the technical advisory group, a small group of representatives from each standard setter that meets periodically, microwave tumor ablation should be coded as surgery.  For liver, assign code 16 (Heat-Radio-Frequency ablation (RFA); for kidney, assign code 15 (Thermal ablation).

Code histology to combined carcinoid and adenocarcinoma (8244/3). The tumor is a mix of adenocarcinoma and carcinoid.

Record the date of the polypectomy as the date of first surgical procedure. Polypectomies are surgery for the purposes of cancer registry data collection regardless of whether or not there is residual tumor after the polypectomy.

Mucinous borderline tumor, intestinal type, of the ovary is not reportable. The behavior is /1. There is no applicable histology code for this histology when it ocurs in the ovary. 

This answer pertains to cases diagnosed prior to 2018. For 2018 and later cases, refer to the Non-Malignant CNS Solid Tumor Rules.

Intraosseous meningiomas are not reportable. You are correct, these are rare meningiomas originating in bone. The term "sphenoid wing meningioma" is sometimes used for an intraosseous meningioma of the sphenoid bone. Yes, it's possible to have a meningioma of the sphenoid wing on imaging that arises from the meninges NOT the bone. Read the available information carefully. When the site of origin is described as "along the sphenoid wing" or "overlying the sphenoid wing" report the meningioma. These descriptions indicate that the meningioma originates from the meninges covering bone rather than the bone itself. Meningioma arising in bone is rare enough, that when present, we would expect it to be clearly stated as such. In the absence of a statement indicating origin in bone, the meningioma is most likely arising from meninges covering the bone.

This carcinoid tumor, described as benign, is not reportable. According to our expert pathologist consultant, this case is not reportable because the pathologist uses "benign" to describe the mucosal endocrine proliferation and based on that, the neuroendocrine cell proliferation is hyperplasia/benign - not reportable.
