First course treatment/Immunotherapy--Prostate:  Is XGEVA, given for bone mets from prostate cancer, abstracted as immunotherapy, or is it an ancillary drug and not recorded?

Do not record XGEVA when given for bone mets from prostate cancer.  See SEER*Rx for more information.

Primary Site--Stomach: How do I code the primary site when the operative report and pathology report state that the tumor site is incisura of the stomach?

Assign C163. Incisura, incisura angularis, gastric angular notch, angular incisure of stomach all refer to the sharp angular depression in the lesser curvature of the stomach at the junction of the body with the pyloric canal. See Gastric angular notch in #12 on page 76 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf.  See also the SEER training website, #12 on the illustration corresponds to the angular notch, http://training.seer.cancer.gov/ugi/anatomy/stomach.html. We will correct the key for this illustration.

First course treatment/Other therapy: How is Sirolimus (Rapamycin) to be coded when given with known chemotherapy agents in a clinical trial? See discussion.

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]?

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).

MP/H/Histology--Sarcoma:  How should Ewing Sarcoma/primitive neuroectodermal tumor (PNET) be coded for a 2012 case?  See Discussion.

SEER SINQ 20031051 applies to cases diagnosed before 2007 and advises:  Code histology as 9260/3, Ewing sarcoma. Ewing sarcoma is a specific histology on the continuum of primitive neuroectodermal tumors. Code Ewing sarcoma as it is more specific than PNET, NOS.

For tumors diagnosed 2007 or later, refer to the MP/H rules.

Apply 2007 MP/H rule H6 and assign the numerically higher ICD-O-3 code that reflects PNET (9364/3).

According to the WHO Tumors of Soft Tissue and Bone, though Ewing sarcoma ICD-O-3 code is 9260/3, Ewing sarcoma with a higher degree of neuroectodermal differentiation present is classically termed peripheral neuroectodermal tumors (PNET).  WHO does not offer guidance how to classify tumors stated to be Ewing sarcoma PNET.

Histology code 9364/3 is assigned for a Ewing/PNET that arises outside of the brain/CNS. Peripheral neuroectodermal tumor (PNET) and peripheral primitive neuroectodermal tumor (PPNET) are Ewing family tumors.

Histology code 9473/3 (PNET, primitive neuroectodermal tumor, central primitive neuroectodermal tumor, or supratentorial PNET) is only used for tumors arising inside the brain/CNS.

First course treatment/Immunotherapy--Heme & Lymphoid Neoplasms: Is donor leukocyte infusion for treatment of hematopoietic neoplasms coded as a bone marrow transplant per the Hematopoetic Manual or as immunotherapy per SEER Inquiry System (SINQ) 20110048?  See Discussion.

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.

Code donor lymphocyte infusion as immunotherapy. SINQ 20110048 is correct. The Hematopoietic Manual will be corrected during the next update.

First course treatment/Chemotherapy: Is metronomic chemotherapy coded as chemotherapy?

Code metronomic chemotherapy as chemotherapy. Metronomic chemotherapy, also referred to as low-dose metronomic (LDM) chemotherapy, is an emerging cancer treatment approach which administers relatively low doses of traditional chemotherapy drugs over a long period of time and without ‘breaks’ in treatment. By using lower doses this method of treatment minimizes the side effects of traditional chemotherapy.

Reportability/MP/H Rules/Histology--Ovary: What is the histology code for an ovarian tumor described as a mucinous borderline tumor, intestinal type?

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.

Reportability--Breast: Is mammary fibromatosis reportable and if so, what histology code is assigned? See discussion.

The pathologist completed a CAP protocol using soft tissue. Pathology revealed a 2.5 cm tumor with invasion of skeletal muscle with deep margins positive for tumor.

Mammary fibromatosis is not reportable. The WHO classification for breast tumors assigns mammary fibromatosis a behavior code of /1. According to WHO, mammary fibromatosis "is a locally infiltrative lesion without metastatic potential…"

MP/H Rules/Histology--Breast: How should histology be coded for a breast primary with resection final diagnosis of "Ductal carcinoma with neuroendocrine features?" See Discussion.

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

Code the histology to 8574/3 for Ductal carcinoma with neuroendocrine features.

Ductal carcinoma is also called "invasive breast carcinoma of no special type." WHO classifies Invasive breast carcinoma with neuroendocrine differentiation as 8574/3.

Neoadjuvant treatment/Grade--Prostate: How should the grade/differentiation field be coded when hormone therapy is given prior to radiation for metastatic prostate cancer? Is hormone treatment "neoadjuvant treatment" in this situation? Per NCCN guidelines, neoadjuvant hormone therapy is strongly discouraged outside of a clinical trial for localized disease. However for metastatic disease, hormone is recommended (gold standard). See discussion.

8/1/15 CT Exam showed enlarged prostate and left seminal vesicle with multiple enlarged pelvic LNs. Findings: suspicious for prostate cancer with invasion of seminal vesicle. Bone scan findings: positive bone mets in multiple sites. PSA 169.0 (elevated). Patient was started on casodex 8/12/15. A prostate biopsy was performed on 9/16/15 to confirm diagnosis, adenocarcinoma Gleason 4+5. Patient's treatment continued with radiation to bone.

For cases diagnosed prior to 2018

Code the grade/differentiation field from the biopsy for this situation. According to experts consulted, hormone therapy does not alter the grade in this case and grade should be coded based on information after hormone therapy when that is the only grade information available.
