20130085 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient was treated in 1999 with Vidaza for myelodysplastic syndrome and had a recent biopsy that demonstrated a transformation to acute myeloid leukemia? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case should be accessioned as a single primary, acute myeloid leukemia [9861/3]. MDS diagnosed prior to 1/1/2001 is not a reportable disease process. However, because MDS is currently a reportable disease process, it must be considered when trying to determine whether the AML represents a separate primary.
Rule M2 does not apply to this case because more than one histology is mentioned in the scenario. According to the Heme DB, MDS can transform to AML. Rules M8-M13 apply to cases involving transformation. In this case, Rule M10 applies because the patient was diagnosed with a chronic neoplasm (myelodysplastic syndrome) followed greater than 21 days later by an acute neoplasm (AML).

20061092 | CS Tumor Size--Breast: Should this field be coded to 999 [Unknown] or 008 [0.8 cm tumor] when the tumor size is not provided on a stereomammotomy biopsy for an in situ malignancy and a subsequent excision demonstrates 0.8 cm tumor of residual in situ disease? | 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 CS tumor size 008 [0.8cm]. A mammotomy specimen is very small, so for this case, the residual tumor size is quite accurate. Size is not a critical data element for in situ breast cancer. |

20021179 | Primary Site/EOD Fields--Head & Neck: In the absence of an actual resection and a pathologic evaluation of the affected area, would a laryngoscopy or CT scan provide a better assessment of the EOD and the primary site? | For cases diagnosed 1998-2003:
For Primary Site and EOD, CT information has higher priority than laryngoscopy. The CT scan gives a better picture of the involvement of the deeper tissues. A laryngoscopy falls into the "physical exam" category more than the "operative" category. The laryngoscopy report is not an "operative" report like those generated from a surgical procedure. |

20170012 | Primary Site/Sarcoma--Breast: How should the primary site and stage be coded for osteosarcoma of breast? Is C509 correct or should the code be a different primary site? When assigning C509, the Collaborative Stage (CS) still pertains to breast cancer and AJCC stages it as a breast cancer and not as a sarcoma. |
Code primary osteosarcoma of the breast to breast, C500-C509. Not all site and histology combinations can be staged in CS or AJCC. 9180/3 of breast cannot be staged using the CS breast schema. Breast (C500-C509) cannot be staged using the CS soft tissue schema. The same is true for AJCC. You can stage this case using SEER Summary Stage. Important: Do NOT change the primary site or histology code based on whether or not the case can be CS or AJCC staged. We need to know how many cases are unable to be staged because of their primary site and histology combinations. |

20140021 | Reportability--Breast: Is an inflammatory myofibroblastic tumor of the breast with metastasis to the lung reportable? | Inflammatory myofibroblastic tumor of the breast with metastasis to the lung is reportable. Metastasis to the lung from the breast tumor indicates that the breast tumor is malignant. All malignant neoplasms are reportable. | 2014 | |

20120089 | MP/H Rules/Histology--Colon: The final diagnosis on a path report for a colon specimen says: Is a colon specimen final diagnosis of carcinoma in situ in a serrated adenoma coded to 8010/2, 8210/2 or 8213/2? | For cases diagnosed 2007 or later, code the histology as 8213/2 [carcinoma in situ in a serrated adenoma].
The steps used to arrive at this decision are:
: Apply ICD-O-3 rule F (Matrix principle) and assign the behavior code /2 when the behavior assigned by the pathologist differs from the usual behavior as given in the ICD-O-3.
: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text) and go to the Colon Histology rules.
: Start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at rule H4. Code the histology as 8213/2.
Note: The histology 8213 (adenocarcinoma in serrated adenoma) will be added to rule H4 in the next revision. |

20100058 | Grade: Can the nuclear grade value be coded in the grade field for any site, or is it restricted to sites where it is specifically listed as an option in the coding manual, i.e., breast, kidney, urinary sites, etc.? | There is no restriction on sites for which nuclear grade can be coded in the grade field. If both differentiation and nuclear grade are specified, differentiation takes priority. | 2010 | |
|
20021166 | EOD-Extension--Kidney: If a "tumor thrombus" in a renal vein is discontinuous from the primary tumor in the kidney, is it still coded to 60 [Tumor thrombus in a renal vein, NOS], rather than 85 [Metastasis]? | For cases diagnosed 1998-2003:
Code the EOD-Extension field to 60 [Tumor thrombus in a renal vein, NOS]. A thrombus can be a bolus of tumor cells within a large vein that may or may not still be connected/contiguous with the primary tumor. However, both a discontinuous and contiguous thrombus are coded to 60. |

20130129 | Histology--Heme & Lymphoid Neoplasms: How is histology coded for a diagnosis of composite lymphoma (follicular lymphoma and small lymphocytic lymphoma, BCL-2 positive)? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL)] per Rule PH15. Code the histology to the non-Hodgkin lymphoma (NHL) with the numerically highest ICD-O-3 code when two or more NHLs are present in the same present in the same lymph node(s) or lymph node region(s), tissue(s), organ(s), or bone marrow. Both follicular lymphoma [9690/3] and SLL [9823/3] are types of NHL. Therefore, the histology is coded to 9823/3.
This composite histology represents a single primary per Rule M4. The rule states to abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s).

20230055 | Reportability/Histology--Heme and Lymphoid Neoplasms: Is "the differential diagnoses include, but not limited to, mantle cell lymphoma, atypical chronic lymphocytic leukemia/small lymphocytic lymphoma and a variant of marginal zone lymphoma" reportable? In the Heme manual, they use differential diagnosis that include reportable conditions as reportable. This can be found under Code 1: positive histology in the Diagnostic Confirmation Coding Instruction section page 18. The phrase "include, but not limited to" makes this not clear. |
This is reportable as 9591/3, B-cell lymphoma, NOS.All diagnoses in the differential are all B-cell lymphomas. The pathologist knows it a B-cell lymphoma but has not determined the subtype. If at a later time a specific lymphoma is determined, update the histology code accordingly. |
