Patient had a core needle biopsy of the right acetabulum. Final diagnosis on the path report is: Atypical cartilaginous tumor (formerly chondrosarcoma, grade 1).

Is this cell type reportable? If so, is it reportable only because the pathologist recorded clarifying text in parentheses? If the text in the parentheses was not available, is the histology "atypical cartilaginous tumor" reportable?

In the Hematopoetic Manual, page 22, it is states: "The use of donor leukocyte infusions for treatment of hematopoietic neoplasms, specifically leukemias, is increasing.  Abstract as bone marrow transplant when a reportable hematopoietic neoplasm is treated with donor leukocyte infusion, even if it is not listed in the treatment section of the Heme db for the specific neoplasm."  Question 20110048 in the SEER Inquiry, it is stated "Donor lymphocyte infusion (DLI) is coded as immunotherapy."  Donor lymphocyte infusion and donor leukocyte infusions are the same procedure.  Please clarify discrepancy as coding is needed for a case treated with donor lymphocytic infusion.

Patient had a skin biopsy and this is the interpretation: NASAL SUPRATIP: INVASIVE BASAL CELL CARCINOMA OF SKIN WITH NEUROENDOCRINE DIFFERENTIATION

NOTE: The deep margin is positive for tumor; peripheral margins negative for tumor. The tumor has a basaloid appearance with focal areas appearing slightly squamoid, and it demonstrates myxoid/mucinous retraction from the stroma. It does not demonstrate peripheral palisading of cells within tumor nests and has nuclear chromatin which suggests neuroendocrine differentiation. Mitotic rate is more brisk than typical basal cell carcinoma as well. The differential diagnosis includes basal cell carcinoma with or without neuroendocrine differentiation, basal cell carcinoma with squamous differentiation, basaloid squamous cell carcinoma, Merkel cell carcinoma and metastatic small cell carcinoma. The tumor is further characterized per immunostains x 9 (controls work well). Tumor cells are positive for Ber EP4 and p63; focally positive for Chromagranin; while negative for EMA, CK20, CK7, TTF-1, CD56 and Synaptophysin. Overall, the staining pattern supports basal cell carcinoma with neuroendocrine differentiation.

1993 Renal pelvis: Papillary urothelial carcinoma

1994 Bladder: Noninvasive bladder ca NOS

6/11/13 Bladder: Noninvasive papillary urothelial carcinoma

8/19/14 Bladder: urothelial carcinoma in situ

2/13/15 Bladder: Papillary urothelial carcinoma

Would this situation be 2 primaries - 1993 Renal pelvis and 1994 Bladder with the 2015 being the same primary as 1993 Renal pelvis? Or 3 primaries - 1993 Renal pelvis, 1994 Bladder, 2015 Bladder?

Should the histology for "Ductal carcinoma with neuroendocrine features" be coded to 8500 (Ductal carcinoma, NOS) or 8574 (Adenocarcinoma with neuroendocrine differentiation)?

We are seeing more use of LI-RAD categories on scans. The final impression on the scan will be LI-RADS Category 5 or LI-RADS Category 4, with no specific statement of HCC. The scans include a blanket statement with the definitions of the LI-RADS categories as below.

LIRADS (v2014) categories

M - Possible non-HCC malignancy

1 - Definitely Benign

2 - Probably Benign

3 - Intermediate Probability for HCC

4 - Probably HCC

5 - Definitely HCC (concordant with OPTN 5)

A previous SINQ, 20010094, indicates that we cannot use BI-RADS categories for breast cancer diagnosis, but those BI-RADS definitions are slightly different. Most often there will be a subsequent clinical statement of HCC, so the question is also in reference to Diagnosis Date. Can we use the date of the scan's impression, which states LI-RADS category 4 or 5, as the Diagnosis Date?

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]?
