The language appears similar to the mucinous cystic neoplasm of the pancreas with high grade dysplasia (8470/2), which was clarified to be reportable in 2014.

The SEER*Rx Database lists Sirolimus as an ancillary agent under the Category section, but as an mTOR inhibitor under the Subcategory. The Remarks section indicates Sirolimus (AKA Rapamycin) is an immunosuppressant, but is also a type of serine/threonine kinase inhibitor. Other types of kinase inhibitors (including Temsirolimus) are types of Chemotherapy. Although the Coding section states this drug should not be coded, Primary Sites (NSCLC and glioblastoma) are listed for this drug.

The SEER*Rx Database page for this drug is confusing. Please address the following.

1) Should Sirolimus not be coded when it is being given as a kinase inhibitor or an immunosuppressant?

2) If Sirolimus is ever treatment, should it be coded only for the primary sites listed?

3) If Sirolimus is given as part of a non-blind clinical trial for another site other than NSCLC or glioblastoma, should the Other Therapy field be coded to 2 [experimental - other treatment]?

As of 2013, radiofrequency ablation is coded to "radiation therapy," chemoembolization is coded to "chemotherapy," and microwave ablation code to "other."  Or, is coding microwave ablation (using heat not alcohol) coded to surgical code "16"? The latest documentation year that I could find in the SEER website regarding the above was 2013. I would appreciate clarification/confirmation of correct coding especially for microwave ablation.

We are seeing the term "incidentaloma" on magnetic resonance imaging (MR) reports of head and also with physician statements. For example, this MR of the head: Impression--Suboptimal study due to motion degradation. Heterogeneously enhancing pituitary gland without evidence of acute abnormality. A 3 mm focus of relative hypoenhancement in the left gland is favored to represent an incidentaloma. Advise correlation with clinical findings.

Also, there are cases where the scans show meningioma and then at a later date it is stated to be an incidentaloma in physician notes.

Is the term "incidentaloma" alone reportable, if the term "tumor" for CNS cases is never stated? When I googled the term, it is stated to mean "tumor."

Pathology report diagnosis: Urethral lesion: Intraductal carcinoma of the prostate, see microscopic. Clinical Information: Urethral Lesion/Hematura. Microscopic Description: The biopsy shows dilated ductal structures filled with anaplastic epithelium showing areas of comedo-type necrosis. The tumor cells have enlarged nuclei prominent nucleoli and mitoses are identified. Surrounding benign prostatic tissue is also present. Immunostains show that the tumor cells stain for PSA, PSAP, P504s but are negative for GATA-3. The other components of the PIN 4 stain CK5/14 and P63 stain the basal cells surrounding the tumor confirming the intraductal nature of the process. Intraductal carcinoma should not be confused with high grade PIN as the former is usually associated with high grade invasive tumor. Is this C619 and 8500/2?

Patient had radical resection of pelvic giant cell tumor of bone in August 2012. Final diagnosis clarified that no features to suggest a frankly malignant giant cell tumor were identified.

July 2013 left upper lobe nodules were removed and found to be consistent with multifocal metastatic lung involvement with a previous pelvic giant cell tumor of bone. However, the pathology report comment specifies there are no histological high-grade features to suggest a malignancy:

While SINQ 20091087 may apply, these metastases clearly arrived in the lung by hematogenous spread. The previous SINQ note refers to a case where the implants/metastases can seed the surrounding pelvic and abdominal structures by rupture of the tumor or intraoperative tumor spillage. That type of spread is not quite the same as the current case showing tumor cells leaving the primary tumor/site and travelling through the blood to implant in the lungs.
