Reportability--Brain: Is angiocentric glioma, WHO grade 1 of the right frontal lobe reportable? If so, how is histology to be coded?
Angiocentric glioma is reportable. The best histology code currently available is 9380/1 [glioma, NOS; uncertain behavior].
According to the WHO Classification of Central Nervous System Tumours, Angiocentric glioma has a behavior of /1. WHO defines it as an epilepsy-associated stable or slowly growing cerebral tumour primarily affecting children and young adults; histopathologicaly characterized by an angiocentric pattern of growth, monomorphous bipolar cells and features of ependymal differentiation.
First Course Treatment: If an "aromatase inhibitor" used as a complement to Tamoxifen is treatment, how should it be coded?
When an aromatase inhibitor is part of the planned first course of therapy, code it under hormone treatment.
When a change of drug is PLANNED, it is part of the same course even if subcategories change. This is the usual situation with Tamoxifen and aromatase inhibitor (for example: Femara). The switch to Femara is planned, so it is not a new course. When a drug change happens that is not planned, it is still the same course if both drugs are in the same category and subcategory. An unplanned drug change to a different subcategory would be a new course.
Reportability--Heme & Lymphoid Neoplasms: For cases diagnosed 2010 and later, are idiopathic thrombocytopenia and autoimmune thrombocytopenia reportable?
Idiopathic and autoimmune types of thrombocytopenia are not reportable. Thrombocytopenia and thrombocythemia are not synonyms. Cytopenia and cythemia have different definitions. See Appendix F: Non-Reportable List for Hematopoietic Diseases.
SEER*Educate provides training on how to use the Heme Manual and DB.

MP/H Rules/Multiple Primaries: When the pathology report from a FNA or other biopsy states an "in situ" carcinoma and the patient waits more than 60 days for a more definitive procedure which documents an "invasive" carcinoma, is this reported as two primaries?
For cases diagnosed 2007 or later:
No. When the invasive component is discovered as part of the work-up phase leading to treatment decisions, the case should not be abstracted as a multiple primary. In the rare instance when a patient has not been treated and is still having diagnostic work-up greater than 60 days after the malignancy is diagnosed, do not count the invasive diagnosis as a new primary.
MP/H/Histology--Thyroid: What is the histology code for primary site of thyroid cancer with the histology of papillary thyroid carcinoma, classical and oncocytic type?
Code the histology to 8342/3, thyroid oncocytic (oxyphillic) papillary carcinoma.
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--Liver: Given that agents can be used that are not chemotherapy drugs, how should treatment be coded for a procedure called a "chemoembolization" when the agent used is not documented?
This issue was discussed among the national standard setters and per the SEER website this issue has been resolved as follows: When "chemoembolization" is done but the agents used are not chemotherapy drugs, then treatment should be coded as "Other Therapy." See http://seer.cancer.gov/tools/codingmanuals/embolization.html
SEER Summary Stage 2000--Melanoma: Can Clark's level classification still used to Summary Stage melanoma? It was previously used by AJCC TNM, but was not included in the 7th edition. I see it is still listed in the CAP protocols for melanoma.
Clark's level can be used to assign in situ, localized or regional summary stage.
If there is a discrepancy between the Clark’s level and the pathologic description of extent, use the higher Summary Stage code.
Reportability/Histology--Testis: Is neoplasm consistent with carcinoid type of monodermal teratoma reportable as a teratoma, NOS, and if yes, what is the histology code?
Carcinoid type of monodermal teratoma or well differentiated neuroendocrine tumor (carcinoid), monodermal teratoma of the testis is reportable. Assign 8240/3 according to the WHO classification for this neoplasm.
The diagnosis of "myelodysplasia" is not reportable.
Myelodysplasia covers a group of disorders that result in the inability to produce enough healthy mature blood cells. Those disorders include: anemia, leukopenia, thrombocytopenia, MDS, refractory anemia, refractory anemia with excess blasts in transformation, refractory anemia with ring sideroblasts, refractory anemia with excess blasts, chronic myelomonocytic leukemia, acute myeloid leukemia. Follow-back to the physician is necessary to determine whether or not a particular case represents a malignancy.
"Myelodysplasia" is also listed in Appendix F: Non-Reportable List for Hematopoietic Diseases.
