20160012 | Reportability--Brain and CNS: Is a thalamic amyloidoma reportable if so what histology code is used? |
Thalamic amyloidoma is not reportable. Amyloidoma (tumoral amyloidosis, amyloid tumor) is a tumor-like deposit of amyloid. It is not neoplastic. Amyloid is a protein derived substance deposited in various clinical settings. |

20160016 | MP/H Rules/Histology--Bladder: Can the histology for a high grade urothelial carcinoma described as having "extensive sarcomatoid dedifferentiation" be coded to sarcomatoid transitional cell carcinoma (8122/3)? Example; TURBT, Final Diagnosis - Urothelial carcinoma, high grade. Type/grade comment: Extensive sarcomatoid dedifferentiation is present (40-50% of tumor volume). |
Code high grade urothelial carcinoma described as having "extensive sarcomatoid dedifferentiation" to sarcomatoid transitional cell carcinoma (8122/3). |

20160041 | First course treatment/Surgery of Primary Site--Skin: How are Surgery of Primary Site and Surgical Procedure of Other Site coded for an eyelid skin primary diagnosed by punch biopsy and treated with an orbital exenteration? See Discussion. |
Unlike most other sites, there is no specific code for a radical surgical procedure of a skin primary. In this case, the patient was diagnosed with a sebaceous cell carcinoma of the lower eyelid skin by punch biopsy. The tumor was large and an orbital exenteration was planned. Despite the extensive surgery performed, skin margins were less than 1 cm. Is an orbital exenteration a "major amputation" (code 60) in this case? Given that the margins were not greater than 1 cm, codes 45 - 47 (which includes a minor (local) amputation) don't seem to apply. However, if this procedure cannot be classified as "minor amputation" then doesn't it seem overkill to refer to the procedure as a "major amputation"?
An alternative would be to code Surgery of Primary Site to 32 for the skin resection (punch biopsy followed by a gross excision of the lesion, margins less than 1 cm) and code Surgical Procedure of Other Site to 2 (non-primary surgical procedure to other regional sites) to record the removal of the globe and orbit as part of the orbital exenteration. Which is correct? |
There is a similar question in the FORDS forum of the CoC CAnswer Forum. CoC is the curator for the surgery codes.
Surgical Procedure to Primary Site - Gross excision of the lesion, code in 30s series Surgical Procedure to Other Site (removal of eye) - code 4

20160071 | 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. |

20160002 | MP/H Rules/Histology--Breast: Which is the correct histology code to use and which MP/H rule applies in the case of a single lumpectomy specimen that demonstrates two separate tumors with the following histologies. 1) Invasive lobular carcinoma 2) Invasive ductal carcinoma with tubular features See discussion. |
Does ductal carcinoma with tubular features qualify for Breast MP/H Rule H28? Or, is it more appropriate to strictly follow Table 2 (not a type of ductal tumor) and apply Rule H29, thus losing the lobular component? |
Abstract a single primary using Rule M13. Assign 8523/3 using rule H29. The code for invasive ductal carcinoma with tubular features (8523/3) is higher than the code for invasive lobular carcinoma (8520/3). H28 does not apply because 8523/3 is not included as a type of duct carcinoma on Table 2. |

20160028 | 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. |

20160058 | First course treatment--Heme & Lymphoid Neoplasms: Are blood thinners, e.g., warfarin, coded as treatment in the Other Therapy data item for polycythemia vera and myelodysplastic syndrome? See Discussion. |
Under the hematopoietic data base, treatment for polycythemia vera shows chemotherapy, immunotherapy, and phlebotomy. Essential thrombocytopenia shows blood thinners, anti-clotting medications, aspirin, chemotherapy, immunotherapy, and other therapy (Anagrelide) (for essential thrombocythemia only) and watchful waiting (for asymptomatic patients). Myelodysplastic syndrome shows bone marrow transplant, chemotherapy, immunotherapy, and stem cell transplant.
SEER*RX under warfarin says: Per the 2012 Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual (page 10), blood thinners and/or anti-clotting agents are to be coded as treatment (Other Therapy) for the following histologies: 9740/4 Mast cell sarcoma 9741/3 Systemic mastocytosis 9742/3 Mast cell leukemia 9875/3 Chronic myelogenous leukemia BCR/ABL 1 positive 9950/3 Polycythemia vera 9961/3 Primary myelofibrosis 9962/3 Essential thrombocythemia 9963/3 Chronic neutrophilic leukemia 9975/3 Myelodysplastic/myeloproliferative neoplasm, unclassifiable. |
Based on information from the National Cancer Institute and the Food and Drug Administration, aspirin and/or other blood thinners are not valid treatment for polycythemia vera and myelodysplastic syndrome. These drugs are often given to relieve symptoms of the disease such as bone pain or side-effects of standard treatments including blood clots. The treatment information found on page 22 (2015 Hematopoietic & Lymphoid Neoplasms coding manual) will be updated and ICD-O-3 codes 9950/3 and 9975/3 will be removed from the list. SEER*RX has been updated to reflect this change. |

20160032 | Reportability--Brain: Is benign lymphangioma of the brain (9170/0) reportable? It is not on the list of non-malignant blood vessel tumors in the National Program of Cancer Registries Clarifications for Central Nervous System (CNS) tumors. |
Lymphangioma of the brain or CNS is not reportable. Lymphangioma is a malformation of the lymphatic system. Even though it has an ICD-O-3 code, do not report it. |

20160056 | MP/H Rules/Histology--Testis: How should histology be coded for a testicular primary with a combination of teratoma, yolk sac tumor and embryonal carcinoma? See discussion.
|
Patient had a radical orchiectomy with the final diagnosis of "Mixed germ cell tumor with the following features -- histologic type: Mixed germ cell tumor (teratoma 50%, yolk sac tumor 25%, and embryonal 25%)." |
Assign 9085/3. Code this combination of teratoma, yolk sac tumor, and embryonal tumor in the testis to mixed germ cell tumor (9085/3) based on the WHO Classification of Tumors of the Male Genital Organs. |

20160021 | 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. |
