20091012 | MP/H Rules/Histology--Head & Neck: If the final diagnosis states "see microscopic description," can the micro information be used to code the histology? See Discussion. | In regards to coding histology for 2007 and forward cases, we are instructed to use the final diagnosis, and any addenda or comments associated with the final diagnosis. We are not to use the microscopic description. However, we are seeing pathology reports with a final diagnosis that also includes the notation "see microscopic description" or "see description". Example: "Left Parotid: High grade carcinoma involving deep lobe with marginal extension. See description." The microscopic description goes on to describe the carcinoma in more detail, which includes a statement "consistent with the ductal type of primary parotid carcinoma." Can we use this microscopic description or not? | For cases diagnosed 2007 or later: When the final diagnosis indicates that the microscopic section contains the detailed diagnosis, use the microscopic description to code the histology. Otherwise, code from the final diagnosis only and not from the microscopic description. The final diagnosis is usually the pathologist's conclusion after consideration of the various choices listed in the microscopic description. The histology code should represent the pathologist's final conclusion. |

20091038 | CS Tumor Size--Breast: Do the tumor size instructions in the CS Manual take priority over those in the SEER manual? See Discussion. | In regards to priority order of sources to be used in coding size for breast and lung, we are instructed to use the site-specific instructions in the 2004 SEER Manual over the general instructions in the CS Manual (see SINQ 20061109). Thus, physical exam size would be used over an imaging size. I&R question 2389 instructs registrars to use an imaging size over a physical exam size. This inconsistency creates confusion for them. Do the answers given in I&R not take into account the information in the SEER Manual? As a SEER Registry, which rules do we tell our hospitals to use? Are ACoS accredited hospitals required to use I&R over SINQ? | 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.The current SEER instructions and the CS instructions for source of tumor size information are the same. The tumor size priority source instruction in the 2004 SEER manual is not included in the 2007 SEER manual. SINQ 20061109 has been updated for clarification. There is no conflict between SEER instructions and I&R instructions at this time. SEER and the CoC collaborate, endeavoring to provide consistent instructions and to resolve inconsistencies. |

20041025 | Immunotherapy/Chemotherapy: Are monoclonal antibodies, such as Avastin and Erbitux, coded as immunotherapy or chemotherapy? See Discussion. | In review of the "FDA-approved oncology agents not listed in SEER Book 8" provided in 5/02, it appears "monoclonal antibodies" are coded as immunotherapy. | Code Avastin and Erbitux as chemotherapy because both of these drugs are growth inhibitors. Code growth inhibitors (cytostatic agents) as chemotherapy. Do not assume that monoclonal antibodies are coded as immunotherapy. | 2004 |

20051020 | CS Extension/CS Site Specific Factor--Breast: How is extension (localized or unknown) and SSF6 (entire tumor in situ or 888) coded for an in situ breast primary in which bone metastasis is diagnosed 4 months following the mastectomy? See Discussion. | In situ breast primary with bone mets. No mets work up prior to mastectomy done 2/04. Path: 2.5 cm mass: ductal carcinoma in situ, solid type, with comedonecrosis (no invasive carcinoma found in mastectomy specimen). Bone scan done 4/04 showed compression fractures. MRI 6/04 showed diffuse metastatic disease of the bones. | 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. First, determine whether the bone mets in this case are progression of disease. If the patient was asymptomatic at the time of the mastectomy, the bone mets are disease progression, not initial stage. If the initial stage includes the bone mets and they are not disease progression, extension must be coded to at least 10. Code site-Specific Factor 6 to 040 [Size of entire tumor coded, size of invasive component not stated]. |

20000260 | EOD-Size of Primary Tumor--Breast: When the pathology report does not specify dimensions for the invasive component, how is tumor size coded? See discussion. | In some cases the tumor has both invasive and in situ components. The pathologist sometimes does not report the size for the invasive portion of the tumor. In most cases, the invasive portion is described as a percentage of the tumor mass. | From January 1, 1998 and forward: Follow the Revised Breast EOD instructions. If the size of the invasive component is not given, record the size of the entire tumor in the EOD-Size of Primary Tumor field. Assign the appropriate EOD-Extension code for the situation. | 2000 |

20120059 | Primary site/Reportability--Breast: Is a "right nipple skin" biopsy that demonstrates squamous cell carcinoma reportable using a primary site of C500? See Discussion. | In the 2011 SEER Manual Reportability Examples, example 3, it states a "biopsy-proven squamous cell carcinoma of the nipple" is reportable when the subsequent resection shows "no evidence of residual malignancy in the nipple epidermis." However, this example does not specify the biopsy is from the nipple skin and the ICD-O-3 does not list nipple skin as a synonym for code C500. | Because the site is specifically stated to "skin" of nipple [C44.5], this case is not reportable.
If possible, you may wish to confirm the type of biopsy performed. If the biopsy was done by FNA or needle biopsy, the biopsy tissue should contain a full-thickness of skin and subcutaneous breast (nipple) tissue. If that is the case, this tumor would likely be a reportable squamous cell carcinoma of nipple [C50.0]. If, however, this was a punch biopsy it is more likely a non-reportable squamous cell carcinoma of the skin [C44.5]. |

20041087 | CS Extension--Head of Pancreas: What code is used to represent extension to the superior mesenteric artery? See Discussion. | In the CS coding scheme for Head of Pancreas, superior mesenteric artery is listed under both code 54 (T3) and 60 (T4). | 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 code 60 for a primary in the head of the pancreas extending to the superior mesenteric artery. CS Extension code 54 should be Superior mesenteric VEIN and code 60 should be Superior mesenteric ARTERY. An errata will be issued by CS. In addition, extension 54 indicates resectable disease and code 60 is not resectable. |

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. |

20031169 | Laterality--Head & Neck: Does the site code C098 need a laterality code? See Description. |
In the SEER EOD-88 3rd edition, page 36, site code C098 does not need laterality. In the SEER Program code manual, 3rd edition, page 93, site code C098 is listed as a site that needs a laterality code 1-9. | Topography code C098 [Overlapping lesion of tonsil] requires a laterality code of 1-9. Follow the laterality guidelines in the SEER Program Code Manual. | 2003 |
|
20081034 | Race, Ethnicity/Spanish Surname or Origin: Which Spanish Surname List (from 1980 census or 1990 census) would SEER prefer us to use to code 7 in Spanish Surname or Origin? See Discussion. | In the SEER coding manual, it refers to "a list of Hispanic/Spanish names" (5e), but does not specify which one to use. Again, for the Computed Ethnicity field, which Spanish Surname List does SEER prefer us to use? | Determine which list is better suited for your geographic area. If the 1990 list is used, determine the probability cut-off that seems most reasonable for your geographic area. | 2008 |
