20091061 | Multiplicity Counter--Head & Neck: How is this field coded when a patient has carcinoma in the same location as a previous primary but it is unknown if there was a disease-free interval? See Discussion. | Patient was diagnosed with squamous cell carcinoma, single tumor of the right true vocal cord in May 2008. Tumor was treated with radiation therapy and chemotherapy. Excision of right vocal cord mass in February 2009 shows squamous cell carcinoma. | Assign code 01 [one tumor only] for the example provided (see discussion). Given the information provided, there is no reason to suspect that the February 2009 diagnosis represents new tumor; therefore, it does not affect the multiplicity counter. It appears that this was the treatment plan for the original diagnosis in May 2008: radiation and chemo followed by excision of the mass. | 2009 |
|
20091039 | CS Tumor Size--Lung:. Does code 997 (diffuse, entire lobe) for lung and main stem bronchus take precedence over a stated tumor size? See Discussion. | Per SPCSM 2007 'Coding Instructions for CS Staging Data Items-CS Tumor Size' item 5c states that code 998 (diffuse, entire lung) for lung and main stem bronchus takes precedence over any mention of size. Does this apply to code 997 as well? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code the stated tumor size rather than 997. Code 997 does not take precedence over tumor size at this time. According to CoC, the instructions in the CS Manual, Part I-27, rule 5c are to alert the user to special circumstances. Code 997 is not included because it is not diffuse for all of the sites listed. The site-specific rules and codes in the schema always take precedence. Further instructions and clarifications will be added to the lung schema, CS Manual Part II-317 in the next version of CS. |

20081107 | Multiplicity Counter/Ambiguous terminology: How should these fields be coded for cases with an unknown date of diagnosis? | If the date of diagnosis is unknown, it is likely that you have little information for this case. Both multiplicity counter and ambiguous terminology fields would probably be coded as unknown. However, if information on the number of tumors and the diagnostic confirmation are available, code these fields as specified in the manual. | 2008 | |

20081083 | Multiple primaries--Lymphoma: Is mediastinal large B-cell lymphoma followed by classical Hodgkin lymphoma reportable as one or two primaries? See Discussion. | Diagnosed 06/06/2006 with mediastinal large B-cell lymphoma, 9679/36. On 05/10/2007, another mediastinal lymph node biopsy done and the diagnosis was recurrent malignant lymphoma, classical Hodgkin's. A Hematopatholgy Consultant states, "it appears likely that the preceding mediastinal diffuse large B-cell lymphoma and the current classical Hodgkin's lymphoma are clonally related and represent different manifestations of the same entity. One might also place this in the spectrum of 'mediastinal gray zone lymphoma' described by Dr. Jaffee and colleagues." | For cases diagnosed prior to 1/1/2010:Report this case as two primaries. Report non-Hodgkin lymphoma followed by Hodgkin lymphoma as separate primaries. According to the Table of Single and Subsequent Primaries for Hematologic Malignancies, mediastinal large B-cell lymphoma and Hodgkin disease are "D" - Different disease processes. For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20081106 | MP/H Rules--Breast: How many primaries for the following? Breast lumpectomy: Three foci of invasive ductal carcinoma. Tumor nodule #1 - Invasive ductal carcinoma. Tumor nodule #2 - Invasive ductal carcinoma with tubular features. Tumor nodule #3 - Invasive tubular carcinoma. See Discussion. |
According to the MP/H rules, this case is reportable as three primaries with histologies coded 8500, 8523 and 8211. However, our QC staff is having a problem accepting this. When the pathologist specifies that a ductal carcinoma has tubular features or is tubular type, isn't s/he saying that tubular is a type of duct? In addition, the first line of the FDx states, "Three foci of ductal carcinoma," which indicates that the pathologists interprets the three nodules to be ductal carcinoma. |
For cases diagnosed 2007 or later: These three tumors are three separate primaries. Rule M12 applies. According to the 2007 MP/H rules, tubular carcinoma is not a type of duct carcinoma. Among the paramount reasons for writing the MP/H rules are the non-standard usage of nomenclature by physicians and the inconsistency in interpretation of these non-standard phrases. The MP/H rules must be applied consistently by each cancer registrar in order for data to be comparable across registries. |

20081126 | MP/H Rules--Brain and CNS: Are stigmata of neurofibromatosis in the brain reportable neurofibromatosis lesions? See Discussion. |
Reference: SINQ 20051108; SINQ 20061018 Three year old patient with history of neurofibromatosis 1. 3/05 MRI of the brain showed right optic nerve glioma. It also showed heterogeneous high t2 signal in the middle cerebellar peduncles and near the genu of the internal capsules bilaterally are stigmata of neurofibromatosis type I. 3/08 MRI showed new mass suspicious for glioma in the hypothalamus. Clinical diagnosis is benign glioma secondary to diagnosis of neurofibromatosis. How many primaries are to be accessioned for this patient? Should the matrix principle be invoked for the second glioma? Should the behavior code for the glioma be 0? |
For cases diagnosed 2007 through 2017 Accession NF (9540/1) when there is CNS tumor -- a glioma or some other intracranial/intraspinal tumor. Stigmata of NF are reportable when the stigmata themselves are reportable tumors. For example, glioma, or another intracranial/intraspinal tumor. Do not report sitgmata that are only termed "stigmata seen on MRI," for example, without other reportable terminology. Do NOT accession NF (9540/1) when there is only peripheral nerve/nervous system involvement. Accession the neurofibromatosis itself only once per patient. Accession any initial neoplasm in the CNS separately. Abstract and code any subsequent CNS neoplasms according to the multiple primary brain rules. Accession three primaries for the case described above.
--> Optic nerve gliomas associated with NF are pilocytic astrocytomas. Code pilocytic astrocytoma as 9421/3 in North America. For cases diagnosed 2018 or later See the 2018 Solid Tumor Rules for Non-Malignant CNS tumors. |

20081004 | First course treatment/Histology--Lymphoma: What treatment, if any, is coded for a patient with methotrexate induced lymphoma when the treatment plan is to take the patient off methotrexate? Also, is there a specific histology for drug induced lymphoma? See Discussion. | Diffuse Large B-cell Lymphoma of soft palate & nasal septum, methotrexate induced, in 5/07. Patient was taken off methotrexate with complete resolution of disease. No other treatment was given. Patient was on methotrexate for treatment of rheumatoid arthritis. | For cases diagnosed prior to 1/1/2010:Treatment: Code the treatment fields to 00 [not done] in this case. Document the discontinuation of methotrexate for rheumatoid arthritis in a text field. Histology: Assign code 9680/36 [Malignant lymphoma, large B-cell, diffuse, NOS]. There is no specific histology code for therapy-related lymphoma. For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20081046 | MP/H Rules--Corpus uteri: How is histology coded for an endometrial tumor described as an "endometrioid adenocarcinoma with prominent squamous metaplasia"? | For cases diagnosed 2007 or later: Endometrioid adenocarcinoma with squamous metaplasia is coded 8570 [Adenocarcinoma with squamous metaplasia]. This falls under the Histology Coding Rules for Other Sites, rule H17. The code for Endometroid adenocarcinoma is 8380. The code for Adenocarcinoma with squamous metaplasia is 8570. The histology with the numerically higher ICD-O-3 code is Adenocarcinoma with squamous metaplasia -- 8570. |

20081120 | MP/H Rules--Sarcoma: How many primaries should be abstracted for chondrosarcoma of right toe in 2002, of right lower leg in 2006 and right tibia in 2007? See Discussion. | A patient had a myxoid chondrosarcoma of the right toe in 2002. This was amputated and staged as T2 - high grade. Patient had a recurrence in the lower right leg in 2006. At this time he had a below knee amputation. The tumor in 2006 was stated to be similar histologically to the 2002 tumor with pathologic comparison done. Then in 2007 the patient presents with pain in right knee and stump. CT says compatible with recurrent disease, but no copies of path sent. Patient then had an above knee amputation, with diagnosis of clinically recurrent chondrosarcoma of tibia. How many primaries should be abstracted? Is 2007 diagnosis a new primary? | For cases diagnosed 2007 or later: Abstract two primaries in this case, 2002 and 2007. The first primary was diagnosed in 2002. The 2006 diagnosis would not be a new primary according to the rules in effect at that time (2004 SEER manual, page 11, rule 5, exception 1). Use the current MP/H rules to compare the 2007 diagnosis to the 2002 diagnosis. Start with rule M3 and stop at rule M10. The 2007 diagnosis is a separate primary. |

20081055 | MP/H Rules--Melanoma: How many primaries are represented if subsequent to a diagnosis of malignant melanoma of skin of left thorax in April 2006, a metastatic melanoma is discovered in the soft tissue of the abdomen and in the skin and subcutaneous tissue of the groin in late 2007? See Discussion. | 4/20/06: skin left lateral thorax, excision: Pedunculated malignant melanoma, 0.5 CM in height, Clark's level 3, Breslow depth 0.5 CM, superficial ulceration noted. No host response. Margins clear. 6/19/06: Four sentinel LNs negative. Interferon therapy. 10/30/07: FNA of soft tissue, left lower abdomen: consistent with metastatic melanoma. 12/20/07 A) sentinel lymph node, left groin, biopsy: No morphologic or immunophenotypic findings support for metastatic melanoma (see comment). B) skin and subcutaneous tissue, left groin, excisional biopsy: Metastatic malignant melanoma (see comment). Lymphovascular invasion identified. Margins free of melanoma. Melanoma 1.5 MM from the closest designated deep margin and 5 MM from the designated 6:00 margin. C) skin, left groin/additional inferior margin, excisional biopsy: No significant histopathologic abnormality. No evidence of villus or melanoma or malignancy. Comment: A 0.8 cm metastatic nodular melanoma is present in the adipose tissue. The underlying skin is unremarkable. There is no evidence of ulceration, melanocytic lesion, melanoma in situ, or regression of melanoma. Block A1 is sent for immunohistochemical studies. The immunophenotypic findings provide no support for metastatic melanoma in lymph node. Please see the immunohistochemical study. The primary MD states "Recurrent intransit mets, left groin." |
For cases diagnosed 2007 or later, this is a single primary, melanoma of the thorax 4/20/06. The subsequent reports mention metastases, but do not document another primary. Do not count metastatic lesions as new primaries. | 2008 |
