20160036 | Reportability/Histology--Head and Neck: Is mammary analogue secretory carcinoma (MASC) of the left submandibular gland reportable and how is it coded? See Discussion. |
The physician is calling it an indolent tumor, pT3/NX/M0 stage 3 with positive margins. Is the correct code C509, 8502/3? |
Mammary analogue secretory carcinoma (MASC) is reportable. MASC is a recently described tumor that predominantly arises in the parotid gland. In this case, if the primary site is submandibular gland, assign C080. We contacted our expert pathologist and he stated that the best code to use for MASC is 8502/3. Override any edits triggered by the combination of C080 and 8502/3. |

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 |

20160009 | MP/H Rules/Histology--Appendix: What is the histology for an appendix resection diagnosis of "Malignant neoplasm of the appendix with the following features: Histologic type: Adenocarcinoma ex goblet cell carcinoid with mucin production (adenocarcinoma arising from goblet cell carcinoid)"? Is this histology best coded to a mixed adenocarcinoma/carcinoid tumor (8244/3)? |
Code histology to combined carcinoid and adenocarcinoma (8244/3). The tumor is a mix of adenocarcinoma and carcinoid. |

20160060 | Mets at diagnosis fields--Heme & Lymphoid Neoplasms (Lymphoma): How are Mets at Diagnosis -- Bone, Brain, Liver, Lung, Lymph Node, and Other -- to be coded for lymphomas in 2016? Are they always 0 if the TNM Stage is I, II, or III? How is bone marrow involvement coded -- in which Mets at Diagnosis field? |
Note: Answer verified Sept. 2019, still valid for current cases. Code all mets at diagnosis fields to 0 when the Stage is I, II, or III. When the lymphoma is Stage IV, one of the mets at dx fields (other than Mets at Dx-Distant lymph nodes) needs to be coded to 1. Stage IV indicates that there is multiple extralymphatic organ involvement, diffuse involvement of an organ; liver, brain, lung or bone involvement, or bone marrow involvement. For bone, brain, liver, and lung, code these as 1 when these sites are involved and they are not the primary site. This is the same instruction for solid tumor neoplasms. For mets at dx-distant lymph nodes, always code to 0. For lymphomas, lymph node involvement is included in stage and not based on whether they are regional or distant. For mets at dx-other, code to 1 for bone marrow involvement or if there is multi extralymphatic organ involvement. |

20160033 | First course teatment/Surgery of Primary Site: Is microwave ablation (using heat not alcohol) coded to a surgery code? See Discussion. |
As of 2013, radiofrequency ablation is coded to "radiation therapy," chemoembolization is coded to "chemotherapy," and microwave ablation code to "other." Or, is coding microwave ablation (using heat not alcohol) coded to surgical code "16"? The latest documentation year that I could find in the SEER website regarding the above was 2013. I would appreciate clarification/confirmation of correct coding especially for microwave ablation. |
According to a consensus answer of the technical advisory group, a small group of representatives from each standard setter that meets periodically, microwave tumor ablation should be coded as surgery. For liver, assign code 16 (Heat-Radio-Frequency ablation (RFA); for kidney, assign code 15 (Thermal ablation). |

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. |

20160045 | 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. |

20160061 | Reportability/Behavior--Small intestine: Is a carcinoid tumor, described as benign, reportable? See Discussion.
|
A segmental resection pathology report states "benign mucosal endocrine proliferation consistent with a 0.3 cm duodenal carcinoid tumor." The diagnosis comment further states, "the separate small endocrine lesion is histologically benign, consistent with a 3 mm carcinoid tumor." This seems to be an example of a description of a microcarcinoid tumor referenced in SINQ 20160011. However, in this new case the pathologist specifically states the tumor is benign.
The WHO definition of microcarcinoid indicates this is a precursor lesion, which seems to indicate it is not malignant. However, SEER's previous answer stated we should report these tumors because the ICD-O-3 definition of carcinoid is 8240/3. Do you think that the mention of the term "benign" in the pathology report is actually related to the size of this lesion? Is the reference to benign mucosal endocrine proliferation referring to the WHO classification (making the case reportable as stated in SINQ 20160011), or is this a situation in which we should apply the Matrix Rule and the case is nonreportable? |
This carcinoid tumor, described as benign, is not reportable. According to our expert pathologist consultant, this case is not reportable because the pathologist uses "benign" to describe the mucosal endocrine proliferation and based on that, the neuroendocrine cell proliferation is hyperplasia/benign - not reportable. |

20160070 | Primary site/MP/H Rules/Histology: What is the appropriate site and histology code for a tumor described as a "Large mass In suprasellar cistern encroaching into sphenoid & ethmoid sinuses", with the pathology described as "INI-1 deficient sinonasal undifferentiated carcinoma"? Of note, this patient has a history of a pituitary adenoma, resected overseas a few months prior to this diagnosis. |
The primary site is unclear. The lesion is intracranial, but this may not be the primary site. In the absence of any additional information, assign C390, 8020/3. According to WHO, sinonasal undifferentiated carcinoma can involve the nasal cavity, maxillary antrum, and/or ethmoid sinus.
SMARCB1 (INI-1) is a tumor-suppressor gene located on chromosome 22q11.2. Tumors that showed loss of expression were SMARCB1-deficient tumors which are characterized by nests, sheets, and cords of cells without any histologic evidence of specific (eg, squamous or glandular) differentiation. |
