20160011 | Reportability--Stomach: Are microcarcinoid tumors reportable? See discussion. |
SINQ 20081076 states carcinoid tumorlets of the lung are not reportable and are defined as being less than 5 mm in diameter and benign. Per the WHO Classification of Digestive Tumours, microcarcinoid tumors are precursor lesions/nodules measuring greater than 0.5 mm, but less than 5 mm (0.5 cm). Is the term microcarcinoid tumor equivalent to carcinoid tumorlet, and therefore not reportable? Or is a microcarcinoid tumor a reportable type of neuroendocrine tumor (NET)? |
Microcarcinoid and carcinoid tumors are reportable. The ICD-O-3 histology code is 8240/3. Microcarcinoid is a designation for neuroendocrine tumors of the stomach when they are less than 0.5 cm. in size. Neuroendocrine tumors of the stomach are designated carcinoid when they are 0.5 cm or larger.
The term microcarcinoid tumor is not equivalent to carcinoid tumorlet. |

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 |

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). |

20160062 | Grade--Kidney: Should WHO/ISUP grade for renal cell carcinoma be coded for cases diagnosed 2016 and later? See discussion.
|
The 2016 WHO Classification of Tumours of the Urinary System appears to be moving away from using Fuhrman grading toward using WHO/ISUP grade. These seem like similar 4 grade staging systems; however, the SEER Manual specifically states to not use the Special Grade System table for WHO/ISUP. We are seeing the WHO/ISUP grade being used on 2016 pathology reports.
Examples of new grading for renal cell carcinomas Histologic type: Clear cell renal cell carcinoma Histologic grade (WHO/ISUP 2016): Grade 3 in a background of 2 (of 4). And Histologic type: Clear cell renal cell carcinoma Histologic grade (ISUP): Grade 2. |
Do not record WHO/ISUP grade in the grade/differentiation field.
Designated fields for this grade system are being proposed for future implementation. |

20160054 | MP/H Rules/Multiple primaries--Melanoma: How many melanoma primaries should be abstracted if, during the workup for a metastatic melanoma of an unknown cutaneous site, an in situ melanoma is also discovered? See Discussion. |
Patient has diagnosis of melanoma with spindle cell features found in a right lower lobectomy specimen. Chart notes indicate this is metastatic from a cutaneous primary of unknown site. Further work up includes a biopsy of the tip of the nose, which is diagnostic for in situ melanoma. Should this be abstracted as two separate primaries, one for an invasive melanoma of unknown primary site and the other for an in situ melanoma of the skin on the tip of the nose? Which MP/H Rule would apply? |
Yes, abstract this as two separate primaries, an invasive melanoma of unknown primary site and an in situ melanoma of the skin on the tip of the nose. Rule M3 applies. |

20160024 | Reportability--Melanoma: Please explain how a CTR is to interpret the guideline in the MP/H rules (Cutaneous Melanoma): Evolving melanoma (borderline evolving melanoma): Evolving melanoma are tumors of uncertain biologic behavior. Histological changes of borderline evolving melanoma are too subtle for a definitive diagnosis of melanoma in situ. Is this to mean that evolving melanoma in situ is not reportable? Or should we follow the guidelines in SEER Question 20130022 that states the reportability terms for melanoma and melanoma in situ. |
Follow the guidelines in SINQ 20130022 for now. When the MP/H rules are revised, new instructions will be implemented.
See also SINQ 200120078 and 20110069. |

20160042 | First course treatment/Date 1st surgical procedure--Colon: Should the date of a polypectomy be recorded in the Date of First Surgical Procedure field when the entire tumor is not removed by polypectomy? See Discussion. |
The patient underwent a polypectomy. The endoscopy report noted the "single piece polypectomy" only partially removed the polyp/mass as the remainder of the mass was more fixed to the wall. The margins were not noted on the pathology report, but were presumably positive given the endoscopy report and the subsequent low anterior resection (LAR) that proved macroscopic residual tumor. Should the date of the polypectomy be recorded in Date of First Surgical Procedure field? Or would the date of the subsequent LAR be recorded since macroscopic residual tumor was present following polypectomy? |
Record the date of the polypectomy as the date of first surgical procedure. Polypectomies are surgery for the purposes of cancer registry data collection regardless of whether or not there is residual tumor after the polypectomy. |

20160073 | MP/H Rules/Multiple primaries/Histology: What histology and how many primaries are coded for a mixed germ cell tumor with a somatic type malignancy (rhabdomysarcoma) if the patient was diagnosed with seminoma of the testis in 2009 followed by a 2015 metastatic germ cell tumor in a retroperitoneal lymph node, stated to be a recurrence of the testicular cancer? See Discussion. |
In September 2009 the patient was diagnosed with seminoma, classical type, following an orchiectomy. Testicular mass recurrence in 2014 was treated with chemotherapy. Then in April 2015 a retroperitoneal dissection of a peri-aortic LN was positive for mixed germ cell tumor with somatic type malignancy (rhabdomyosarcoma) involving 1/11 nodes. Path Comment: major component of tumor is teratoma, rhabdomyosarcoma represents <5% of mass. Now in October 2016, the patient has a retroperitoneal mass biopsy positive for spindle cell sarcoma with rhabdomyosarcomatous differentiation. The comment section of the pathology report states, "Given the history of a germ cell tumor w/ rhadbomosarcomatous component, the findings are consistent with a recurrence of rhabdomyosarcomatous component of germ cell tumor." Can a seminoma transform to a mixed germ cell tumor with a somatic type malignancy (see SINQ 20140082 - testicular teratoma with somatic type malignancy)? |
According to our expert pathologist consultant, yes, seminoma could transform to a mixed germ cell tumor with a somatic type malignancy. He advises us to code this case as 9061/3. From our expert pathologist consultant: This occurs as "reprogramming" of the initial germ cell tumor/seminoma cell. The process is not understood, but genetic studies support this progression concept. Most often the next step is teratoma. It is out of the teratoma that the somatic malignancy usually comes. I do wonder about the possibility that this was really an embryonal carcinoma which resembles a seminoma - occasionally this can be a difficult separation. I wonder if they radiated the scrotum following the orchiectomy, also, given the scrotal recurrence. |

20160022 | MP/H/Histology--Breast: What MP/H Rule, histology, and behavior code for a breast primary apply to the following?
2 foci DCIS, solid, high grade (Grade 3) w/microca++ |
Apply the Multiple Primaries/Histology, Breast Rule H3: DCIS and a more specific in situ are coded to the more specific histology term which in this case is solid. Code the histology to ductal carcinoma in situ, solid type (8230/2). Based on the information provided, there is no invasive component. The term "microca ++" means micro-calcifications are present, not micro carcinoma. |
