Secondary polycythemia vera is not reportable. See Appendix F.

Primary polycythemia vera is a condition in which there is an overproduction of blood cells due to a neoplastic process. Secondary polycythemia vera is an over production of red blood cells caused by a co-morbidity, in this case, volume depletion.

WHO classifies intraductal carcinoma of the prostate 8500/2. According to WHO, "the hallmark of intraductal carcinoma of the prostate is a proliferation of prostate carcinoma cells that is within and may significantly expand the native prostatic ducts and acini, with the basal cell layer at least partially preserved." Further, differentiation between intraductal carcinoma and infiltrating high-grade carcinoma of the prostate may require basal cell stains. Under Prognosis, WHO states: " intraductal carcinoma of the prostate on prostate biopsies is often associated with high-grade cancer (with a mean Gleason score of 8) ."

So while it may seem counter-intuitive, assign behavior code /2 when the diagnosis is intraductal carcinoma of the prostate.

For this case, code primary site to C189 [colon, NOS] per Rule PH24.

Mantle cell lymphoma usually begins with lymph node involvement and spreads to other tissue. However, it can begin in a lymphocyte such as those in the GI tract. Per the Abstractor Notes section in the Heme DB, patients usually present with advanced disease. About half will have some combination of B symptoms. Swelling of lymph nodes and spleen are usually present. Bone marrow, liver and GI tract involvement occurs in a very high percentage

No. These schwannomas are not intracranial and therefore, are not reportable to SEER. The occipital nerve is not one of the 12 intracranial nerves (i.e., Abducens, Auditory (vestibulocochlear), Facial, Glossopharyngeal, Hypoglossal, Oculomotor, Olfactory, Optic, Spinal Accessory, Trigeminal, Trochlear, and Vagus).

For cases diagnosed 1998-2003:

Code EOD-Lymph Nodes fields as follows for the examples given:

1) 9 [Unknown; not stated] for a "hilar mass"

2) 2 [Mediastinal] for a "mediastinal mass"

3) 2 [Mediastinal] for "enlarged" or "greater than 1 cm," if used to describe any of the named lymph nodes listed under code 2 in the EOD-Lymph Nodes field.

The code for retinoic acid depends upon the primary site and histology of the tumor. Code retinoic acid (also called Vitamin A, tretinoin, ATRA, all-transretinoic acid or Vesanoid) in the Immunotherapy field as 01 [Immuno administered as first course therapy] for acute promyelocytic leukemia. This drug is given to patients as an alternative to chemotherapy.

For all other sites/histologies, code retinoic acid in the Other Cancer-Directed Therapy Field. Use code 2 [Other experimental cancer-directed therapy] or 3 [Double-blind clinical trial, code not yet broken] if the drug is given as part of a protocol. If the drug is not being given as part of a protocol or you don't know whether it is part of a protocol, use code 1 [Other cancer-directed therapy].

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Yes, the term "focal areas" of in situ carcinoma describes a minimal in situ component.

For cases diagnosed 2021 and later

VIN II-III is reportable based on ICD-O-3.2 which lists squamous intraepithelial neoplasia, grade II as 8077/2 making it reportable. Also see SINQ 20120094.

Code cutanteous leiomyosarcoma to skin. Leiomyosarcoma can originate in the smooth muscle of the dermis. The WHO classification designates this as cutaneous leiomyosarcoma. The major portion of the tumor is in the dermis, although subcutaneous extension is present in some cases.
