20081064 | MP/H Rules--Bladder: Is a TURBT in 4/07 that demonstrates papillary carcinoma (8130/3) followed two weeks later with biopsies that demonstrate high grade flat dysplasia/carcinoma in situ (8010/2) two primaries? |
For cases diagnosed 2007 or later, rule M6 applies and this is a single primary. Flat transitional cell carcinoma and carcinoma in situ of the bladder are synonymous. See the definition of "Flat Tumor (bladder)/Noninvasive flat TCC" in the Urinary Terms and Definitions section of the 2007 MP/H manual. |

20081093 | CS Extension: How is CS Ext coded for the following? Rretroperitoneal primary Cystic mucinous tumor with intraepithelial carcinoma There is no CS Extension code for intraepithelial ca in the retroperitoneal scheme. |
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.According to the American College of Surgeons I & R system, assign code 10 [confined to site of origin] for intraepithelial carcinoma of the retroperitoneum. |

20081042 | Primary Site/CS Extension--Lymphoma: How are these fields coded for an epidural lymphoma that extends into the bone marrow of the adjacent vertebral body? | For cases diagnosed prior to 1/1/2010:After verifying that the lymphoma originated in the epidural space, code to C729 [nervous system, NOS (epidural)]. This is a rare type of extranodal lymphoma. Assign CS extension code 80 for lymphoma with bone marrow involvement. 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. |

20081045 | MP/H Rules--Melanoma: How is histology coded for a regressing melanoma? See Discussion. | How is histology to be coded for the following tumors? Example 1: Path showed malignant melanoma Histologic type: superficial spreading. Regression: present. Example 2: Shave, mid back: malignant melanoma, lentigo melanoma type, level II, regression: present and prominent. |
For cases diagnosed 2007-2014: Apply MP/H Melanoma Histology Coding rule H5 and code the histologic type of the melanoma. Code example 1 as 8743 [Superficial spreading melanoma]. Code example 2 as 8742 [Lentigo maligna melanoma]. |

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. |

20081031 | MP/H Rules--Breast: How many primaries are abstracted if a mastectomy specimen reveals two separate invasive tumors: #1: Invasive apocrine carcinoma, poorly differentiated, 1.2cm, (9 o'clock). -Apocrine ductal carcinoma in situ (DCIS), high-grade with comedo necrosis; 2.0cm (9:30 o'clock). #2: Invasive ductal carcinoma, well-differentiated, 1.0cm (12:30 o'clock). -Minor component of DCIS, low-grade? See Discussion. |
In the MP/H Rules, Table 1 lists apocrine as a type of intraductal carcinoma. Apocrine does not appear in Table 2, the list of specific duct carcinomas. If Apocrine is a type of ductal carcinoma, then Rule M11 would make this a single primary. If it is a single primary, what is the histology? | For cases diagnosed 2007 or later: Using rule M11, there is one primary in the left breast. Apocrine is a specific duct carcinoma. To make this more clear, apocrine will be added to Table 2 in a future revision. To code the histology, go to the multiple tumors module and start with rule H20. Stop at rule H29 and code the histology with the numerically higher ICD-O-3 code, 8500/3. |

20081084 | Reportability: Is a tubular adenoma reportable if the final diagnosis is "high grade atypia" and the diagnosis comment is "atypia limited to muscularis mucosa areas of pseudostratification [formerly qualifying for carcinoma in situ]"? |
This case is not reportable. The pathologist would need to include "carcinoma in situ" as part of the final diagnosis in order for this case to be reportable. |

20081021 | Primary Site/Surgery of Other Site--Leukemia: If hairy cell leukemia is diagnosed at splenectomy, and 1 month later a bone marrow confirms the same diagnosis, is the primary site coded to spleen or bone marrow? If the site is bone marrow, is the splenectomy coded to 2 (regional) or 4 (distant) in the surgery field? | For cases diagnosed prior to 1/1/2010:Primary site: Code the primary site to C421 [bone marrow] per primary site coding instructions for leukemia in the 2007 SEER manual, page 70.
Surgery of other site: Since all surgical procedures for hematopoietic diseases are coded in the data item Surgery of Other Site, assign code 1 [Nonprimary surgical procedure performed]. 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. |

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. |

20081073 | CS Extension/Ambiguous terminology--Pancreas: Should an exception be made for "abuts" or "encased/encasing" regarding CS pancreas extension? See Discussion. |
According to the CS Manual regarding ambiguous terminology, we do not accept "abuts" or "encased/encasing" as involvement. According to the March/April 2008 issue of "CA, A Cancer Journal for Clinicians", vol 58, number 2, an article concerning Pancreas staging by M.D. Anderson researchers/clinicians recommends defining unresectable involvement of the celiac axis/mesenteric artery with the terms "abutment" as involvement of 180 degrees or less of the circumference of the vessel, and "encasement" as more than 180 degree involvement. A large comprehensive cancer center in our area has already adopted these guidelines. |
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.Follow the current CS instructions regarding ambiguous terminology. "Abuts" and "encased/encasing" are not involvement. The American College of Surgeons Commission on Cancer provided the following in response to this question: This concept can be considered for CS version 2, but it would need to be made in conjunction with acceptance of that same theory in AJCC 7th Edition so that the stage can be derived. Many times what can be defined and accepted in a closed environment of a single institution research project cannot be duplicated and accepted across the nation and in every community facility. Would pathologists specify the > or < 180 degree involvement in every pathology report? It would also have to be reviewed to see if this idea has been accepted by the larger oncology community, or just the idea of a single institution. |
