20081124 | CS Extension--Brain and CNS: How is CS Extension coded for a malignant meningioma that demonstrates extension into adjacent brain tissue? For malignant brain tumors, code 60 represents extension into the meninges. Would code 60 be the correct code for extension from a malignant meningioma into brain tissue? |
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.Assign CS extension code 60 for malignant meningioma with extension to adjacent brain tissue. According to the I&R, this section of CS was taken directly from SEER Summary Staging, since AJCC does not have a staging system for these tumors. |

20081048 | CS Lymph Nodes/CS Mets at Dx--Ovary: How are renal lymph nodes coded for ovary primaries? | 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 involvement of renal lymph nodes under CS Mets at Dx. Renal lymph nodes are not listed as regional lymph nodes for ovary; therefore, code involvement of renal lymph nodes under CS Mets at Dx. |

20081090 | MP/H Rules: Does the presence of metastases affect the application of the MP/H rules? See Discussion. | Single lung tumors presenting in each lung but the patient also presents with bone mets? Would rule M6 apply? Or do the bone mets represent additional tumors? | For cases diagnosed 2007 or later, the MP/H rules do not apply to metastases. Ignore metastases when applying the rules. For the case above, use rule M6 and abstract as two primaries (right lung and left lung). The bone mets are ignored. |

20081103 | CS Lymph Nodes--Breast: What code should be used for the the following? There is no mention of LNS clinically; the patient has neoadjuvant therapy; and the LNS are matted pathologically. | 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.Use the information from the pathologic evaluation to code CS Lymph nodes. In the nodes evaluation field, assign code 6 [Regional lymph nodes removed for examination with pre-surgical systemic treatment or radiation and lymph node evaluation based on pathologic evidence]. See CS Lymph Nodes note 4. |

20081123 | Reportability--Brain: Is angiocentric glioma, WHO grade 1 of the right frontal lobe reportable? If so, how is histology to be coded? | Angiocentric glioma is reportable. The best histology code currently available is 9380/1 [glioma, NOS; uncertain behavior]. According to the WHO Classification of Central Nervous System Tumours, Angiocentric glioma has a behavior of /1. WHO defines it as an epilepsy-associated stable or slowly growing cerebral tumour primarily affecting children and young adults; histopathologicaly characterized by an angiocentric pattern of growth, monomorphous bipolar cells and features of ependymal differentiation. |

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. |

20081015 | MP/H Rules/Multiple primaries--Lung: Should a subsequent primary be abstracted using rule M8 for a patient diagnosed in January 2000 with adenocarcinoma of the right upper lung if the patient initially sought alternative therapies and presented in September 2007 for a right upper lobe lung mass with extension into the mediastinum, mediastinal lymph node mets and a pericardial effusion? See Discussion. |
After more than seven years, the patient in this case decided to proceed with the originally suggested standard therapy. Is this a multiple primary case because the tumors are "diagnosed" more than 3 years apart? Or should we assume this is further progression of the 2000 case because it was originally only treated with alternative therapies? The clinician in this case indicates the patient is being referred for treatment to the right upper lung originally diagnosed in 2000. |
For cases diagnosed 2007 or later: Do not abstract a 2007 primary for this case. From the information provided, there is disease progression/extension and lymph node metastasis in 2007; but there are no new lung tumors in 2007. Therefore, the 2007 MP/H rules do not apply. |

20081025 | MP/H Rules/Histology--Anus: What is the correct histology code and MP/H histology rule to use for AIN-3 arising in a polyp? See Discussion. | Patient has colonoscopy with excision of small 5mm polyp in rectum (no mention of anus or anal canal); path reads out: AIN-3 (anal intraepithelial neoplasm grade 3).
In coding the histology using the "Other Sites" rules, H2 would be the first rule that applies for this case. However, we lose the fact that the AIN-3 arose in a polyp (H3). Is this how SEER wants these cases coded? |
For cases diagnosed 2007 or later, apply rule H2 and assign histology code 8077/2 (squamous intraepithelial neoplasia, grade III). Apply the rules in order, H2 precedes H3. | 2008 |

20081039 | Diagnostic Confirmation/Histology--Hematopoietic: How are these fields coded when the final pathologic diagnosis for a bone marrow biopsy differs from the final clinical diagnosis of a hematopoietic disease? See Discussion. | Frequently, pathology reports describe hematopoietic diseases using ambiguous terms. Flow cytology and cytogenetics may be obtained. It appears that the clinician is the person who pulls all the information together for a diagnosis. Example: Bone marrow biopsy is most compatible with chronic phase myeloproliferative disease. Path comment: Differential would include CML. Outside hematology report indicates an elevated peripheral WBC, primarily neutrophils. Flow cytometry showed 1.0 % of the white cells are myeloid blasts of abnormal phenotype, additionally finding 7.3 % basophils. Flow reported peripheral blasts at 1.2 % and peripheral basophilia. Cytogenetics report showed abnormality with trisomy of chromosomes 13 and 21. This finding is consistent with a clonal abnormality suggestive of acquired disease. Results were consistent with the absence of the t(9,22)(q34;q11) translocation or fusion product associated with CML. Subsequent clinical impression: Bone marrow evaluation most consistent with CML. Overall features most consistent with CML. |
For cases diagnosed prior to 1/1/2010:Code the Diagnostic Confirmation field as 1 [positive histology]. Code the ICD-O-3 morphology based on the clinician's statement. The code in Diagnostic Confirmation pertains to the best method used to confirm the presence of cancer over the entire course of the disease. Therefore, if a bone marrow report confirms cancer, code 1 [positive histology] in Diagnostic Confirmation. Code the histology using all of the information available. The clinician has access to all of the information relating to this case. The pathologist had only the bone marrow. Code the histology recorded by the clinician. 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. |
