20091023 | Sugery of Primary Site--Breast: When a patient is simultaneously diagnosed with bilateral breast cancer and bilateral mastectomies are done, do you code the total mastectomies to 40 or 41 or 42? | Abstract cancer of the left breast and cancer of the right breast as separate primaries. Code the surgery for each primary independent of the other primary. For the first primary, assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast]. For the second primary, assign the code for the procedure performed on that site. |

20091060 | MP/H Rules/Multiple Primaries--Head and Neck: How many primaries are to be accessioned for a case in which a second tumor occurs in an area previously involved by direct extension from a prior primary located in an adjacent site? See Discussion. | Patient diagnosed in August 2007 with squamous cell carcinoma in the right tonsil. This tumor extended to the base of tongue. Treatment consisted of radiation and chemotherapy. In May 2008, the patient was found to have squamous cell carcinoma of the base of tongue. How many primaries are to be accessioned for this case? Rule M7 states that tumors in sites with ICD-O topography codes that are different at the second or third character are multiple primaries. The topography code for base of tongue differs from that of tonsil. Would rule M7 apply? On the other hand, the base of tongue was involved by the tonsil primary which was diagnosed less than one year before. | For cases diagnosed 2007 or later: The May 2008 diagnosis is not a new primary. Base of tongue involvement was originally present in August 2007. The May 2008 diagnosis does not represent new tumor. The 2007 rules apply to new tumors only; therefore, the 2007 rules do not apply to this case. |

20091003 | MP/H Rules/Histology--Peritoneal primary: Can the cell types from the primary site and a metastatic site be combined to code histology? See Discussion. | Patient has vaginal mass biopsy diagnosed as 'papillary carcinoma with psammoma bodies.' Two weeks later the patient has laparoscopy with multiple peritoneal biopsies, diagnosed as 'well differentiated serous adenocarcinoma'. Patient stated to have peritoneal primary with mets to vagina and was treated with chemotherapy. Do we code the histology to 8441/31 from the primary site biopsies, or can we use 8460/3, combining the cell types from the primary and metastatic sites? Please see SINQ 20041062 for a similar question before the 2007 MP/H rules. | For cases diagnosed 2007 or later, assign code 8441 [serous adenocarcinoma, NOS]. Code the histology from the primary site when available. Do not combine histologies from primary and metastatic sites. In this primary peritoneal case, the diagnosis from the peritoneal biopsies was serous adenocarcinoma. |

20091105 | Multiple Primaries--Hematopoietic: How many primaries and which histologies should be reported for a case presenting with a 2005 diagnosis of CLL/SLL, 2006 clinical diagnosis of MDS and a 2008 diagnosis of AML? See Discussion. |
2005 diagnosis of CLL/SLL (9670) with lymph node involvement, treated with FCR. 2006 clinical diagnosis of MDS secondary to chemo (9987) with CLL/SLL in remission. 2008 biopsy reveals AML (9861). Per Seer Hematopoietic Table, 9987 & 9861 are a single primary. In 6/2008 patient receives bone marrow transplant. 2009 status post BMT, BM biopsy reveals RAEB-1 (9983). Is this still the same disease process or a new primary (since status post BMT)? |
For cases diagnosed prior to 1/1/2010:Two primaries should be abstracted. Using the Definitions of Single and Subsequent Primaries for Hematologic Malignancies table, compare 9670 (SLL) in 2005 and 9987 (MDS secondary to chemo) in 2006. This is two primaries. MDS can transform to AML. On the Definitions of Single and Subsequent Primaries for Hematologic Malignancies table, 9987 (MDS) and 9861 (AML) are a single primary. The AML would be documented in follow-up. (While 9670/SLL and 9861/AML are two different primaries, the SLL has already been reported.) RAEB is a form of MDS. On the Definitions of Single and Subsequent Primaries for Hematologic Malignancies table, 9987 (MDS) and 9983 (RAEB) are a single primary. The RAEB would be documented in follow-up. (While 9670/SLL and 9983/RAEB are two different primaries, the SLL has already been reported.) 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. |

20091057 | CS Site Specific Factor--Lymphoma: Can the term "intermediate risk" be used to code IPI score? See Discussion. | Patient has Hodgkin disease. The physician states that the patient has bulky stage IIA intermediate risk disease. Is the term "risk" another way of stating IPI score? If so, how would intermediate risk be coded? | 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 SSF 3 for lymphoma based on the IPI score stated in the record. Do not attempt to interpret statements or terms in order to assign a code to SSF 3. If no further information is available for this case, code SSF 3 999 [Unknown]. |

20091117 | MP/H Rules/Histology--Breast: How is histology to be coded for a breast primary described as "tubular carcinoma (well differentiated invasive ductal carcinoma)"? See Discussion. | How are terms that are modified by parentheses to be interpreted? Do terms in parentheses modify the stated diagnosis and thus have priority over the stated diagnosis? Or would rule H17 apply and histology would be coded as duct and other carcinoma? For this case, the wording of the diagnosis and use of parentheses seem to indicate that tubular is a type of ductal carcinoma. Tubular is not listed as a specific duct carcinoma in the MP/H rules histology tables for breast. |
For cases diagnosed 2007 or later, code the histology as tubular carcinoma [8211/3]. This is not a case of tubular AND infiltrating duct. The histology is stated to be tubular. Tubular is not a specific type of duct carcinoma. | 2009 |

20091081 | Reportability/Histology--Brain and CNS: Is an "inflammatory myofibroblastic tumor" reportable for Brain and CNS sites? See Discussion. | Histology code 8825/1 (Inflammatory Myofibroblastic Tumor) is not listed in the ICD-0-3 Primary Brain and CNS Site/Histology listing for reportable Brain/CNS tumors. | If the inflammatory myofibroblastic tumor is primary in one of the sites specified below and diagnosed 1/1/2004 or later, it is reportable.
Reportable brain and CNS tumors are any benign and borderline primary intracranial and CNS tumors with a behavior code of /0 or /1 in ICD-O-3 diagnosed 1/1/2004 and later, of the following sites:

20091073 | Grade: Can FIGO grade be used to code Grade/Differentiation? See Discussion. | SINQ 20020059 says not to use FIGO grade to code differentiation. It also says SEER is evaluating whether the ICD-O-3 sixth digit differentiation codes accurately represent the FIGO grade. For the time being, do not code FIGO grade. What is the result of the evaluation? Any new information regarding FIGO grade? | 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.Do not code FIGO grade in the grade field. The conversion from a three-grade system to a four-grade system does not work for FIGO grade three. Since FIGO G3 includes both Poorly differentiated and undifferentiated, it cannot be converted. FIGO grade may be captured in a CS site specific factor in the future. |

20091128 | MP/H Rules/Multiple primaries--Breast: How many primaries are to be accessioned when a patient was diagnosed with breast carcinoma in 2001 and was subsequently diagnosed with a mammary carcinoma in a chest wall mass in 2008? See Discussion. |
Patient was diagnosed with invasive lobular carcinoma of the right breast in April 2001. Following modified radical mastectomy in May 2001, the patient was disease free. In December 2008 the patient was diagnosed with a right chest wall mass, invasive poorly differentiated mammary carcinoma with lobular origin. If this is a new primary in 2008, would we code the primary site to breast or chest wall? Please see I&R answers 25924, 22163 and 26155 with similar case scenarios that give two different answers. One response indicates coding this type of scenario as new primary to chest wall and the other two responses indicate this should not be a new primary because the chest wall is a metastatic site. The pathology report does not state that this is metastatic and it is unknown if there is breast tissue left behind at the chest wall. |
For cases diagnosed 2007 or later, this case is a single primary. The chest wall (NOS) is a metastatic site for breast cancer. There is no mention of residual breast tissue, so the 2008 diagnosis cannot be a new primary. "Chest wall" is an ambiguous term. It can mean the internal chest wall or the external chest wall. When the path report states that the "recurrence" is in residual breast tissue, this is most likely the external chest wall and the residual breast tissue is part of the breast not removed by the MRM. In contrast, skin or the chest wall, NOS, are regional metastases. |

20091119 | MP/H Rules/Multiple primaries--Lung: How many primaries are to be reported for an adenocarcinoma of the lung in the right middle lobe of the lung and bronchioalveolar carcinoma, non-mucinous type in the right upper lobe? See Discussion. |
Bilobectomy revealed two tumors, adenocarcinoma in the right middle lobe and bronchioalveoar carcinoma non-mucinous type in the right upper lobe. MP/H rule M10 states that tumors with non-small cell carcinoma (8046) and a more specific non-small cell type (chart 1) are a single primary. Does rule M10 apply to only those cases for which one tumor is stated to be non-small cell, NOS? Or do we use chart 1 to identify specific subtypes? For this case, using chart 1, would we note that bronchioalveolar is a subtype of adenocarcinoma and count this case as a single primary? Most of the MP/H rules schemas have a rule making an adenocarcinoma and a more specific type of adenocarcinoma a single primary. Would we apply rule M10 to this case and count it as a single primary? Or would we move on to rule M11 and count the case as two primaries? |
For cases diagnosed 2007 or later, Rule M11 applies. Accession two primaries. Rule M10 applies only to cases for which one tumor is stated to be "non-small cell carcinoma." |
