20081036 | MP/H Rules--Breast: Is inflammatory breast cancer always one primary per lifetime? Or is a subsequent inflammatory breast cancer a second primary if diagnosed more than five years later? | For cases diagnosed 2007 or later, a diagnosis of inflammatory breast cancer more than five years after a previous diagnosis of inflammatory breast cancer is a separate (new) primary. See rule M5 in the Breast Multiple Primary Rules. | 2008 | |

20081108 | CS Extension--Pancreas: How is this field coded for a head of pancreas primary with involvement of the inferior vena cava? | 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 54 [Blood vessel(s) major]. The inferior vena cava is one of the major blood vessels. The inferior vena cava is located just behind the head of the pancreas. The hepatic artery, the superior mesenteric vessels and the portal vein are nearby. |

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]. |

20081051 | MP/H Rules/Histology--Prostate: Path said adenocarcinoma of the prostate with an endometroid adenocarcinoma component. What histology code is used? | For cases diagnosed 2007 or later: Assign code 8500 [duct carcinoma]. According to The World Health Organization (WHO), the term endometrioid carcinoma of the prostate is now called Prostate Duct Carcinoma. Using Rule H11 (one type), code 8500 (duct carcinoma) for this rare type of tumor. Do not stop at Rule H10 because this is not acinar. |

20081066 | Multiplicity Counter/Type of Multiple Tumors--Breast: How should these fields be coded when path shows a 1.2 cm infiltrating carcinoma with lobular features and several foci of infiltrating lobular carcinoma [7 foci described as multifocal], 1 large focus, and numerous foci of LCIS and CIS with lobular and ductal features? Should we count the foci or separate tumor nodules, ignore them, or code unknown values for these fields? See Discussion. | Scenario: 10/17/07: Right axilla soft tissue bx - infiltrating mammary ca with lobular features arising within apparent breast tissue present within axilla. Tumor size 1.2 cm. 11/3/07: Right breast, reexcision lumpectomy - Several foci of infiltrating lobular CA. (2) foci & (5) foci within specimen (multifocal). (1) large focus also present. No lymphovascular invasion identified. Numerous foci LCIS. Pleomorphic LCIS & CIS with lobular and ductal features. Margins free of invasion however margins diffusely involved with LCIS.
When do you count foci or separate tumor nodules, when do you ignore them, and when do you code unknown values for these fields? Coding instruction 3b states, "When the tumor is multifocal or multicentric and the foci of tumor are not measured, code as 99." Instruction 4b states, "Use code 01 when there is a single tumor with separate foci of tumor." Finally, instruction 6b states, "Use code 99 when the tumor is described as multifocal or multicentric and the number of tumors is not given," which seems to imply that if we know the number of tumors, we would code that number. |
Multiplicity Counter: Use instruction 4b. Since there is one measured tumor and the foci were not measured, code the multiplicity counter 01 [One tumor only]. Type of Multiple Tumors: Code Type of multiple tumors 00 [Single tumor]. |

20081105 | Primary site/Surgery of Primary Site--Lymphoma: What is the primary site for lymphoma involving lymph nodes and tonsil? Is a tonsillectomy coded as surgery for lymphoma? See Discussion. | 6/1/2008 cervical lymph node biopsy showed lymphoma. A 6/3/2008 CT Chest/abdomen showed mediastinal and mesenteric lymphadenopathy. A 6/15/2008 tonsillectomy is performed for markedly enlarged right tonsil. Tonsil pathology reveals extensive lymphoma involvement. Nothing in the chart specifies the primary site. Should this be a C778 primary because of 3 lymph node areas plus tonsil (a lymphatic organ)? Or should it be coded to C099 Tonsil? Is this tonsillectomy coded as surgical therapy? If so, is it surgery of primary site or surgery of other site? |
For cases diagnosed prior to 1/1/2010:Code the primary site to tonsil (C099). This advanced stage lymphoma involves an extranodal site (tonsil) and that site's regional lymph nodes (cervical). The lymphoma has also spread to non-regional lymph nodes (mediastinal and mesenteric). Code the tonsillectomy as surgery of primary site. 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. |

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. |

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. |

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. |

20081041 | MP/H Rules/Histology--Thyroid: How many primaries are to be reported and what histology is to be coded for an anaplastic/undifferentiated thyroid carcinoma with sarcomatoid transformation likely arising in association with a papillary thyroid carcinoma? Thyroid contains one tumor: 12.5 cm in greatest dimension...almost completely replaces entire thryroid gland. | For cases diagnosed 2007 or later: This is a single primary using rule M2; a single tumor is always a single primary. The histology code for this case is 8260/3 [Papillary carcinoma of thyroid]. Begin with Histology Coding rule H8. Stop at rule H17 and code the histology with the numerically higher ICD-O-3 code. |
