20160078 | First course treatment/Radiation Therapy--Prostate: How do you code fiducial markers for prostate cases? |
Do not code fiducial markers as a form of radiation treatment; rather, code the radiation therapy in the radiation treatment section. Fiducial markers are small metal spheres, coils, or cylinders that are placed in or near a tumor to help guide the placement of radiation beams during treatment. |

20160035 | Reportability/Histology--Pituitary Gland: How are Rathke cleft cyst and Rathke pouch tumor distinguished and are they both reportable? |
Rathke cleft cyst is not reportable. Cysts are not neoplastic. However, Rathke pouch tumor (C751, 9350/1) is a reportable neoplasm for cases diagnosed 2004 and later. The Rathke pouch is coded to the pituitary gland. Benign and borderline pituitary tumors have been reportable since 2004. |

20160066 | MP/H Rules/Histology--Breast: What histology code and MP/H Rule applies to the Histologic Type of "invasive ductal carcinoma with metaplastic stroma" for a single breast tumor? See Discussion. |
The patient had a partial mastectomy with final diagnosis of invasive ductal carcinoma with metaplastic stroma. Knowing that metaplastic breast carcinoma has a worse prognosis than other types of breast cancer, is metaplastic stroma a synonym for metaplastic carcinoma when used in this context? |
Code to metaplastic carcinoma, 8575/3. According to our expert pathologist consultant, "The term 'metaplastic stroma' implies that at least a portion of the carcinoma has undergone a 'metaplastic' change from epithelial in appearance to 'stromal' in appearance. I assume this is what CAP means by 'Invasive mammary carcinoma with matrix production,' which the WHO equates to metaplastic carcinoma." |

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. |

20160015 | Multiple primaries--Heme & Lymphoid Neoplasms: Could you please clarify Note 2 found in Rule M10, which is " 'Transformations to' (acute neoplasms) and 'Transformations from' (chronic neoplasms) are defined for each applicable histology in the database." Do the neoplasms being considered have to contain the words 'chronic' and/or 'acute'? |
Hematopoietic neoplasms that transform generally don't have 'chronic' or 'acute' as part of their preferred name. The 'chronic' and 'acute' designations are determined by the usual course of the neoplasm. Chronic neoplasms are generally slow growing while acute neoplasms grow fast and are more widespread. Not all Hematopoietic neoplasms transform. Each neoplasm that has the ability to transform has the transformations listed under the 'Transformations to' and/or 'Transformation from' sections in the Hematopoietic database.
For example, Diffuse large B-cell lymphoma (histology code 9680/3) has no histologies/neoplasms listed under 'transformations to.' This means that this neoplasm does not transform to any other neoplasm. There are multiple histologies/neoplasms listed under 'Transformations from' indicating the neoplasms listed under the Transformations from are the chronic neoplasms, and DLBCL is the acute neoplasm. If DLBCL (9680/3) occurs at the same time, within 21 days, or greater than 21 days of any of the histologies listed under 'Transformations From,' rules M8-M13 apply. If DLBCL (9680/3) occurred at the same time as a neoplasm not listed in the Transformations sections, the acute and chronic rules do not apply. |

20160040 | Reportability--Thyroid: Is a final diagnosis of "non-invasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP) reportable when the diagnosis comment states this tumor was historically classified as encapsulated follicular variant of papillary thyroid carcinoma? See Discussion. |
The term "non-invasive follicular thyroid neoplasm with papillary-like nuclear features" is now being used, instead of the previous classification of an encapsulated malignant thyroid tumor. Recent evidence supports a very minimal risk of aggressive behavior for these tumors, and pathologists in our area are no longer classifying these as malignant in the final diagnosis. |
As of January 1, 2021 Non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) C739 is no longer reportable for cases diagnosed 1/1/2021 forward. See the ICD-O-3.2 material on the NAACCR website,https://www.naaccr.org/icdo3/#1582820761121-27c484fc-46a7 _____________________________________________ Answer for cases diagnosed 1-1-2017 to 12/31/2020 Report NIFTP and assign ICD-O-3 morphology code 8343/2. See the NAACCR document, page 3, https://20tqtx36s1la18rvn82wcmpn-wpengine.netdna-ssl.com/wp-content/uploads/2017/01/What-You-Need-to-Know-for-2017.pdf |

20160023 | Grade/Histology--Digestive System: What is the grade for neuroendocrine tumor (NET) or neuroendocrine carcinoma (NEC) of gastrointestinal morphologies described as: 1) NET G1 (M8240/3) and NET G2 (M8249/3) or 2) neuroendocrine carcinoma, low grade (M8240/3) and neuroendocrine carcinoma, well differentiation (M8240/3) and neuroendocrine carcinoma, moderate differentiation (M8249/3)? The SEER Instructions for Coding Grade for 2014+, Coding for Solid Tumors section, #3 state: Code the grade shown below (6th digit) for specific histologic terms that imply a grade. NET and NEC are not included in the specific terms. |
You may code grade as follows.
Grade 1 – NET G1 (M8240/3)
Grade 2 – NET G2 (M8249/3)
Grade 1 – neuroendocrine carcinoma, low grade (M8240/3) or neuroendocrine carcinoma, well differentiation (M8240/3)
Grade 2 – neuroendocrine carcinoma, moderate differentiation (M8249/3) |

20160031 | MP/H Rules/Histology--Brain and CNS: What is the code for Rosette-forming glioneural tumor from a pathology report of a brain tumor biopsy for a date of diagnosis in 2015? See Discussion. |
This diagnosis is not listed in the ICD-O-3 though it is listed as code 9509/1 for this specific tumor in the 2007 WHO classification of Tumours of Central Nervous System. (See link: http://link.springer.com/article/10.1007/s00401-007-0243-4/fulltext.html.) |
Assign 9505/1 for Rosette-forming glioneuronal tumor. The new code, 9509/1, has not been implemented in the United States. 9505/1 is to be used until the new code is implemented. See page 7 of the NAACCR Guidelines for ICD-O-D Implementation, effective January 1, 2014, http://www.naaccr.org/LinkClick.aspx?fileticket=u7d3sB71t5w%3d&tabid=126&mid=466. |

20160014 | Surgery of primary site--Lung: Should microwave ablation be coded as treatment for lung cancer, and if so, how should it be coded? |
Code microwave tumor ablation as surgery. For lung, assign code 15.
This question was discussed by the technical advisory group – a small group of representatives from each standard setter which meets periodically. The group agreed on this consensus answer. |

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. |
