20081098 | MP/H Rules/Histology--Colon: How do you use Rule H5 or H6 to code "moderately diff adenoca with mucinous component"? | For cases diagnosed 2007 or later, code the histology 8140 [Adenocarcinoma]. Rule H6 applies because the final diagnosis is not "mucinous adenocarcinoma" and the percentage of mucinous adenocarcinoma is not stated. Rule H13 does not apply because "component" is not a term that indicates a specific histology. |

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. |

20081005 | Histology/Behavior--Brain and CNS: How are these fields coded for an "anaplastic glioneuronal neoplasm with spongioblastic architecture"? See Discussion. |
Scenario: Addendum from Mayo Clinic review, IHC and consultation made dx of "anaplastic glioneuronal neoplasm with spongioblastic architecture". The original micro states 'high grade glial neoplasm w/o characteristic features of glioblastoma multiforme in that it lacks areas of significant necrosis, no nuclear palisading nor endothelial vascular proliferation...." |
The best code available according to our pathologist consultant is 9505/3 [Ganglioglioma, anaplastic]. According to our consultant, while ganglioglioma is traditionally a benign tumor, anaplastic ganglioglioma is classified as malignant by WHO (page 103), and comes as close to fitting the description of this tumor as any other term. |

20081114 | Reportability--Brain and CNS: Is hygroma reportable? See Discussion. |
Benign brain guidelines indicate that named tumors that have been assigned an ICD-O-3 code are reportable. However, per I&R: "Most cystic hygromas (9173/0) are fetal malformations and occur in patients less than two years old. If this patient was an adult, they are primarily treated with surgery. Hygroma (used in a general sense) is a response to trauma (i.e., subdural hematoma) and as such, is not a "new growth" and would not be reportable either as a cyst or as a neoplasm. Unless the patient had some sort of operation, I'd hesitate to include the case as a reportable benign tumor." How is the cancer registrar to distinguish between reportable and non-reportable hygromas? Example: Brain MRI showed diffuse cerebral volume loss and incidental bilateral frontal subdural hygromas (histology code 9173/0). Reference: I&R 14825 |
Hygromas are not reportable. This instruction will be added to the next revision of the benign brain rules. According to an expert in the field, hygromas are not neoplastic. Hygromas are cystic dilations of a localized subarachnoid or subdural accumulation of clear fluid related to an excess accumulation of CSF, typically related to an old hemorrhage that somehow prevents reabsorption of CSF. |

20081044 | MP/H Rules/Behavior--Melanoma of Skin: How are histology and behavior coded for a "malignant melanoma in situ with regression"? See Discussion. | Per the microscopic portion of the path report, there is a zone of regression within the confines of the lesion, such that the possibility of antecedent invasive disease at the site cannot be ruled out with certainty. | For cases diagnosed 2007 or later: Code malignant melanoma in situ with regression to 8720/2 [Melanoma in situ]. Code the histology according to the histologic type specified in the pathology report final diagnosis. Code the behavior as specified in the pathology report. Regression does not affect the coding of histology or behavior. See Melanoma Histology Coding rule H5. See 2007 SEER manual instructions for coding behavior, page 84. |

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. |

20081019 | Multiple Primaries--Lymphoma: How many primaries are abstracted for a patient with a 1995 periaortic lymph node biopsy showing lymphocytic lymphoma, diffuse small cleaved probable intermediate grade B cell positive, followed by stomach biopsies on 6/18/05 showing diffuse large B cell lymphoma and on 6/24/05 showing malignant lymphoma, tumor cells positive for [CD20] B cell respectively? | For cases diagnosed prior to 1/1/2010:There are two primaries:
According to the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, 9673 [Malignant lymphoma, lymphocytic, diffuse, intermediate] and 9680 [Malignant lymphoma, large B-Cell, diffuse] are separate primaries. Again, according to the table, 9680 [Malignant lymphoma, large B-Cell, diffuse] and 9591 [Malignant lymphoma, non-Hodgkin, NOS] are the same primary. 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. |

20081054 | First course treatment: Is subsequent treatment with R-ICE first course or second course therapy if the patient underwent ABVD x2 cycles and subsequent imaging showed no response to treatment and evidence of progression [new adenopathy] for a lymphoma case? See Discussion. |
Patient was initially diagnosed with Hodgkin Lymphoma, Nodular Sclerosing on 3/3/06. Patient received ABVD x 2 cycles. Had disease reassessed in May, 2006, no response to treatment, showed evidence of progression (new adenopathy). Patient's pathology from 3/06 was sent for consult: Diagnosis was Hodgkin with some overlapping features of B-cell Non Hodgkin Lymphoma. Treated 5/18/06 with R-ICE FOR NHL. |
The R-ICE treatment in this case is not part of the first course. Documentation of treatment failure and/or disease progression signifies the end of the first course of treatment. |

20081086 | Reportability: Is a case reportable if a benign diagnosis is obtained on a resection that follows a positive needle aspiration? See Discussion. | Fine needle aspiration of the thyroid diagnosis was "positive for malignant cells, favor medullary carcinoma." Subsequent thyroidectomy was reported as benign. | This case is reportable. The cytology is positive. Report as medulary carcinoma of the thyroid. | 2008 |
