20081088 | CS Lymph Nodes/CS Mets at Dx: How should these fields be coded for an in situ diagnosis when the patient was diagnosed by biopsy only and there is no information in the chart regarding an evaluation of lymph nodes or metastatic sites? See Discussion. | In reference to the case below, does it make a difference if the CS T stage is known based on the primary excision but there is no clinical information in the record regarding the nodes or metastasis evaluation. This scenario is seen on outpatient records of breast biopsies and melanoma excisions; i.e., punch bx followed by gross excision of the lesion but the medical record contains no clinical information or statement of everything else normal. I&R Question 17625 2/16/2006 A patient was diagnosed with ductal carcinoma in situ by needle core biopsy of the right breast. There was no further information in the chart stating if or where the patient went for staging work-up and treatment. What are the codes for CS Extension, CS Regional Lymph Nodes and CS Distant Mets at Dx? I&R Answer: Sufficient tissue must be taken to determine the T category. If this is the case, CS Extension = 00. Unless the physician makes the statement that the physical exam is negative, code the CS Regional Lymph Nodes = 99 CS Distant Mets at DX = 99. |
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 Lymph Nodes and CS Mets at Dx 00 [None] for an in situ diagnosis with no other information. The CS instructions state that CS LN's should be coded 00 for in situ because in situ by definition is non-invasive. The same logic applies to CS mets in the case of in situ. The I&R answer will be revised. |

20081111 | MP/H Rules/Histology--Breast: If an in situ carcinoma diagnosed in 2007 demonstrates comedo necrosis, should the histology be coded to comedocarcinoma in situ? See Discussion. |
According to the new MP/H rules, we code descriptive features. There is no coding guidance or reference to "necrosis" within the breast MP/H rules. Based on SEER SINQ 20021002, the "comedo necrosis" would not be coded at all for pre-2007 cases. Does this still hold true for cases diagnosed after January 1, 2007? |
For cases diagnosed 2007 or later, comedo necrosis is not synonymous with comedocarcinoma. If no further information is available for this case, code as carcinoma in situ. |

20081101 | MP/H Rules/Multiple primaries--Lung: If a 1.7 cm LUL lung tumor is not treated surgically, would a 2.1 cm tumor in the same lobe three years later be a new primary? See Discussion. |
In 2004 the patient has a 1.7cm squamous cell carcinoma diagnosed in the LUL of the lung treated with radiation and chemotherapy. In 2007, the patient was diagnosed with a 2.1cm squamous cell carcinoma in the LUL treated with radiation. According to the lung MP/H rules, the 2007 tumor would be a new primary. Given that there was no surgery, would the second tumor be progression of disease or would it be a new primary? |
For cases diagnosed 2007 or later: If the tumor diagnosed in 2004 was successfully treated and disappeared, apply the MP/H rules for lung. According to rule M8, the 2004 tumor and the 2007 tumor are multiple primaries. If there was no disease-free interval between tumor occurrences, that is, if the 2007 tumor is still the same tumor that was diagnosed in 2004, the MP/H rules do not apply. |

20081122 | MP/H Rules/Histology--Breast: Patient has single invasive left breast tumor diagnosed in 2008. Final pathology diagnosis is "Invasive solid papillary carcinoma". No mention of ductal in report. What is histology? | For cases diagnosed 2007 or later: As of July 2010: Code the histology 8503 [Infiltrating papillary adenocarcinoma]. This is solid papillary, not solid AND papillary carcinoma. Solid is an adjective modifying papillary, in other words, a subtype of papillary. We do not have a code for solid papillary, so we code to the NOS, papillary using rule H14. |

20081001 | CS Tumor Size: Can an 'ulcerated mass' be used to code CS tumor size? See Discussion.
|
The CS Manual (p. 26, 4.a.) states do not code the size of the polyp, ulcer or cyst. However it states that a 'cystic mass' can be used to code TS if it is the only size given. Scopes Text: 'ulcerated' mass based at anal verge & ext 3-4 cm up into rectum. | 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 CS Tumor size using the size of an ulcerated mass.

20081053 | Multiple primaries--Lymphoma: Is a splenectomy done for non-Hodgkin lymphoma diffuse large B-cell of the spleen a composite histology and a single primary if a perihilar lymph node with Hodgkin lymphoma classic type is found at the time of this surgery? |
For cases diagnosed prior to 1/1/2010:This is two primaries -- Non-Hodgkin lymphoma (NHL) in the spleen and Hodgkin lymphoma (HD) in a lymph node. Composite lymphoma is NHL and HD both in a single lymph node. 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. |

20081003 | Reportability--Brain and CNS: For von Hippel Lindau disease with multiple hemagioblastomas, is each hemangioblastoma reportable as a new primary? See Discussion. | Diagnosis of von Hippel-Landau disease, multiple brain surgeries between 2002 and 2007 for recurring hemangioblastomas, 9161/1. This disease manifests as multiple (recurring) hemangioblastomas. | For cases diagnosed 2007-2014:
If the hemagioblastomas occur in sites with different ICD-O-3 topography codes, they are separate primaries.
Please note: Rule M4 in the Benign & Borderline Intracranial and CNS Tumors MP/H coding rules on the SEER website has been corrected to read: Tumors with ICD-O-3 topography codes that are different at the second (Cxx), third (Cxx) and/or fourth (Cxx) characters are multiple primaries.(http://www.seer.cancer.gov/tools/mphrules/benign_brain.html) |

20081039 | Diagnostic Confirmation/Histology--Hematopoietic: How are these fields coded when the final pathologic diagnosis for a bone marrow biopsy differs from the final clinical diagnosis of a hematopoietic disease? See Discussion. | Frequently, pathology reports describe hematopoietic diseases using ambiguous terms. Flow cytology and cytogenetics may be obtained. It appears that the clinician is the person who pulls all the information together for a diagnosis. Example: Bone marrow biopsy is most compatible with chronic phase myeloproliferative disease. Path comment: Differential would include CML. Outside hematology report indicates an elevated peripheral WBC, primarily neutrophils. Flow cytometry showed 1.0 % of the white cells are myeloid blasts of abnormal phenotype, additionally finding 7.3 % basophils. Flow reported peripheral blasts at 1.2 % and peripheral basophilia. Cytogenetics report showed abnormality with trisomy of chromosomes 13 and 21. This finding is consistent with a clonal abnormality suggestive of acquired disease. Results were consistent with the absence of the t(9,22)(q34;q11) translocation or fusion product associated with CML. Subsequent clinical impression: Bone marrow evaluation most consistent with CML. Overall features most consistent with CML. |
For cases diagnosed prior to 1/1/2010:Code the Diagnostic Confirmation field as 1 [positive histology]. Code the ICD-O-3 morphology based on the clinician's statement. The code in Diagnostic Confirmation pertains to the best method used to confirm the presence of cancer over the entire course of the disease. Therefore, if a bone marrow report confirms cancer, code 1 [positive histology] in Diagnostic Confirmation. Code the histology using all of the information available. The clinician has access to all of the information relating to this case. The pathologist had only the bone marrow. Code the histology recorded by the clinician. 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. |

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. |

20081100 | MP/H Rules/Histology--Rectum: When not specifically mentioned as part of the histology, is the adenoma a second histologic type, or just a further physical description of the tumor? See Discussion. |
Rectal tumor resection (APR) path report final dx: "mucinous carcinoma, see comment". The comment is the CAP-format tumor summary, which states "histologic type: adenocarcinoma with extensive mucin production (mucinous or colloid carcinoma). Additional pathologic findings: adenomas - tumor arises in a tubulovillous adenoma". If you follow the rules and only use the final dx, you would code a different histology than if you use the 'additional path findings.' |
For cases diagnosed 2007 or later Other Sites histology rule H12 applies in this case. Assign histology code 8263 [adenocarcinoma in tubulovillous adenoma]. Use information from the CAP protocol and from comments associated with the final diagnosis to code histology. The fact that the malignancy arose in a polyp can be taken from anywhere in the medical record; not limited to the final diagnosis. Based on the information provided for this case, the histology is adenocarcinoma with extensive mucin production (mucinous or colloid carcinoma) arising in a tubulovillous adenoma. |
