20130170 | MP/H Rules/Histology--Breast: What is the histology code for "invasive carcinoma of the breast, no special type" as the final diagnosis on a pathology report? See Discussion. |
Recently pathology reports for breast primaries are no longer listing invasive ductal carcinoma as the histology on many cases if the treating physician calls the cancer an invasive ductal carcinoma. The pathology report (final diagnosis and synopsis) state this is invasive carcinoma, no special type.
Upon inquiry to the pathology department, the response received stated, In 2012, the WHO got rid of ductal carcinoma as a specific type. So what would have been called Invasive ductal carcinoma, Not Otherwise Specified (NOS), is now being called Invasive carcinoma, No Special Type (NST). In the new WHO classification, lobular, tubular, cribriform, mucinous, etc. are the special types. But ductal is gone.
Is this a change in terminology? Should these cases be coded as 8500/3 [ductal carcinoma, NOS] or 8010/3 [carcinoma, NOS]? |
Code the histology to ductal carcinoma, NOS [8500/3] for a pathology report with a final diagnosis of "invasive carcinoma, no special type." Do not code the histology to carcinoma, NOS [8010/3].
The 4th Edition of the WHO Classification of Tumors of the Breast refers to invasive ductal carcinoma as invasive carcinoma, no special type. The ICD-O-3 code remains the same as invasive duct carcinoma [8500/3]. The next revision to the MP/H Solid Tumor Rules will clarify this issue. |

20130190 | Reportability: Is a thymoma, type B3 malignant and, therefore, reportable? See Discussion. |
Recent information received from a registrar/pathologist states the WHO classifies well-differentiated thymic carcinoma [8585/3] as a synonym for type B3 thymoma. |
For cases diagnosed prior to 2021 Thymoma, type B3 [8585/1] is not reportable. Well-differentiated thymic carcinoma [8585/3] is reportable. WHO lists well-differentiated thymic carcinoma as a synonym for type B3 thymoma, but indicates the behavior code differs as indicated above. See the applicable SEER manual for cases diagnosed 2021 and later. |

20200011 | Race: How should race information from linkages be incorporated into the coding of Race? See Discussion. |
Race information is provided in the Centers for Medicare and Medicaid Services (CMS) linkage results. Oftentimes it matches what is coded in the database, but other times it does not. In situations where the CMS (or other) linkage provides a race value that differs from the coded Patient set, are we to ignore the CMS stated race given the SEER Manual instructions indicating self-reported race has priority or should we add the different Race values from linkages as an additional race (ex. Race 02)? |
Use self-reported race as the priority when information on race is available. Use the associated text field to document why a particular race code was chosen when there are discrepancies in race information. Generally, race information is used from linkages when race data is missing or unknown, or to enhance data. We will add clarification on linkages in the next SEER Manual update. |

20010012 | Surgery of Primary Site--Breast: What code is used to represent this field for a breast primary treated with a "bilateral mastectomy"? See discussion. |
Pt diagnosed with rt breast primary opted to be treated with rt modified radical mastectomy and lt simple mastectomy. Path revealed invasive ductal carcinoma on the rt and ductal carcinoma in situ on the lt. Path reported 14 axillary lymph nodes were found in the mastectomy specimen. |
There are two primaries. For cases diagnosed 1/1/2003 and after: For the rt breast, code Surgery of Primary Site to 51. The contralateral left breast malignancy is not involved with the right breast primary by either direct extension or metastasis. Codes 42 and 52 are used to capture prophylactic mastectomy of the opposite noncancerous breast. In this case, the opposite breast has cancer so these codes cannot be used. Code Scope of Regional Lymph Node Surgery to 5 and Surgical Procedure of Other Site to 0. For the lt breast, code Surgery of Primary Site to 41, Scope of Reg LN Surgery to 0, and Surgical Procedure of Other Site to 0. |

20021130 | EOD-Extension--Breast: If a negative bone scan is followed by a bone marrow biopsy that is positive for metastatic disease, is the bony involvement used when coding extension [85] or as progression of disease (ignore mets when coding extension)? See discussion. |
Pt diagnosed with ductal carcinoma of the breast in May. On June 1, oncologist recommended chemo and XRT and planned a metastatic workup. A June 6 marrow MR consistent with mets. June 8 bone scan showed scoliosis of the L-spine with scattered focal areas of increased activity probably related to degenerative changes in the spine. On June 29, biopsies were done of the T2 vertebra with path diagnosis of metastatic adenocarcinoma consistent with breast primary. Chemo started July 15. For cases diagnosed 1998-2003, is EOD extension code 85 correct? We felt that the bone mets was found within 4 months of diagnosis and is not progression of disease. |
For cases diagnosed 1998-2003: Code the EOD-Extension field to 85 [metastasis]. Bone metastasis was documented during the original metastatic workup. Metastasis to the bone was suspected soon after diagnosis and confirmed prior to the start of treatment. The length of time between the diagnosis and the confirmation of the bone metastasis was not used to code extension on this case. The pt was still being worked up as evidenced by the fact that treatment had not yet started. |

20071096 | Multiplicity Counter--Prostate: How is multiplicity counter to be coded for a clinically inapparent prostate cancer for which sextant needle biopsy cores on left and right sides are positive for adenocarcinoma? See Discussion. | Prostate cancer typically presents as multifocal diffuse disease. The coding exercise in the MPH rules presentations coded prostate cancer as one tumor. Reference: SEER Training Web Casts - Other Sites Rules Practicum |
Code the number of tumors present if known. This information can be taken from any part of the record, including imaging and prostatectomy. If the only information available is "diffuse," or "multifocal," assign code 99. Do not assume there are multiple tumors just beacause there are multiple biopsies. When there is no information about the number of tumors, code Multiplicity Counter to 99 and Type of Multiple Tumors to 99. | Prostate | N/A | 2007 |

20180105 | 2018 Solid Tumor Rules/Histology--Lung: What is the appropriate histology code for the case below in the Discussion section? Is there a difference between adenocarcinoma in situ (bronchioloalveolar carcinoma), non-mucinous type (8252/2) and adenocarcinoma in-situ, mucinous? See Discussion. |
Procedure: Wedge, resection specimen, Laterality: Right, Tumor site: Right upper lobe, Tumor size: 1.0 cm in greatest dimension, Histologic type: Adenocarcinoma in-situ, mucinous, Histologic grade: N/A, Visceral pleura invasion: Not identified, Tumor extension: N/A, Margins: Uninvolved, Lymphocytosis. |
Assign 8253/2 for adenocarcinoma in situ, mucinous. New codes were added in 2018 for mucinous adenocarcinoma in situ for lung cancer only as all cases were not invasive. Pathologist are discouraged from using the term BAC. In-situ lung tumors can now be identified as either mucinous or non-mucinous and the appropriate ICD-O code should be assigned based on diagnosis. |

20150042 | Surgery of Primary Site--Breast: Is the surgery code 42 or 52? Does it matter that the procedure states no axillary LN, but the pathology found 2 additional LN? See discussion.
|
Procedure stated = Bilateral skin-sparing mastectomies, left axillary sentinel lymph node biopsy. On the pathology report it indicates two additional lymph nodes were removed that were not SLN. The axillary aspect measures 2 x 2 x 1 cm. Two lymph nodes are identified ranging from 0.5 up to 1 cm. The lymph nodes are bisected and entirely submitted. Final Diagnosis Left breast, mastectomy including nipple: no residual carcinoma; FINAL DIAGNOSIS for LN = Lymph nodes, left axillary sentinel #1; excision: Two lymph nodes examined - negative for tumor (0/2); Two lymph nodes - negative for tumor (0/2) |
Assign surgery of primary site code 42. It is possible to obtain lymph nodes in a mastectomy specimen without an axillary dissection. Remember to capture the excised lymph nodes in the scope of lymph node surgery field. |

20230079 | Solid Tumor Rules/Histology--Cutaneous Melanoma: How is histology coded for a 2023 diagnosis of “early lentiginous melanoma in situ” of the skin? See Discussion. |
Previous SINQ 20091100 has a similar scenario and the instruction was to code as lentigo maligna (8742/2); however, it does not appear to be applicable to cases diagnosed after 2020. The WHO Blue Book does not list melanoma, lentiginous type or lentiginous melanoma in situ as an alternate term for lentigo maligna and neither do the STR or the ICD-O-3.2. |
Assign code 8742/2 (lentigo maligna) for “early lentiginous melanoma in situ.” ICD-O-3.2 lists the preferred term for 8742/2 as lentigo maligna (C44._). |
