20071009 | MP/H Rules/Multiple Primaries/Laterality--Brain and CNS: How many primaries are to be abstracted and how is laterality to be coded for two meningiomas, one occurring at the midline and the other in the right termporal region? See Discussion. | MRI of the brain shows two meningiomas: One is stated to be 'midline' (laterality code 9) and one is stated to be in the 'right' temporal region. The rules state if same site (C700), same histology & laterality is same side or one side unknown, then abstract as single primary. Based on this, the MRI findings would be one primary, but how should laterality be coded? | For cases diagnosed 2007 or later, abstract two primaries. The lateralities of both meningiomas are known. Right (code 1) and midline (code 9) are different lateralities. | 2007 |

20071060 | Reportability/Ambiguous Terminology--Esophagus: Is a case with a biopsy diagnosis of "... focal areas suspicious for adenocarcinoma in situ change" reportable if the diagnosis on the partial esophagectomy specimen only includes the phrase "... with foci of high grade dysplasia; no invasive carcinoma identified"? |
The case is not reportable. The biopsy with a suspicious result (suspicious for adenocarcinoma) was disproven by the esophagectomy. |

20071003 | MP/H Rules/Histology--Prostate: If a patient is stated to have prostate "cancer" but a pathology report is not available nor is a specific histology stated in the medical record, can this histology be coded to 8140 [adenocarcinoma] instead of 8000/3 [cancer] because the vast majority of prostate cancers are adenocarcinomas? | For cases diagnosed 2007 and later, the correct histology code is 8000/3 [cancer]. The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Other Sites Histology rules because no specific rules have been developed for prostate primaries.
To determine the histology, start at the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Code the histology documented by the physician when there is no pathology/cytology specimen or the pathology/cytology report is not available. Code the histology as 8000/3 [cancer] because that is the only available information. In the absence of a pathology report or any other histologic confirmation, code the histology based on the information available. |

20071039 | Histology--Hematopoietic, NOS: If an initial bone marrow diagnosis is "...more compatible with CMML/MPD" and within three months the final diagnosis per the oncologist is "MPD/CMML with acute myeloid leukemia transformation," is histology coded to CMML or AML? See Discussion. | 09/06 BM Bx elsewhere was "compatible with MDS but more compatible with CMML/MPD" per MD notes. 10/06 BM Bx "...poor prognosis MDS, best classified as RAEB-2" 11/06 BM Bx "myeloproliferative CMML with leukemic transformation" (on evaluation for BMT) 12/12/06 Pt was admitted with rapidly progressive disease & was started on chemo to try to get into remission for BMT. Final dx by oncologist is "MPD/CMML with acute myeloid leukemia transformation". |
For cases diagnosed prior to 1/1/2010:Code CMML for this case. Code the histology at initial diagnosis. This patient had rapid progression, but the initial diagnosis was "more compatible with CMML/MPD." 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. |

20071117 | MP/H Rules/Histology--Brain: How many primaries are reported and what is the histology for a single brain tumor described as a low grade astrocytoma at the time of the initial partial resection and a low grade glioneuronal neoplasm at the time of the subsequent total resection? See Discussion. | On 4/20/07 a partial resection of a brain tumor is interpreted as low grade astrocytoma. Patient has a gross total resection on 8/13/07 with this diagnosis: low grade glioneuronal neoplasm (see comment). Comment: This case has been reviewed at ---. Dr. agrees with our interpretation (low grade glioneuronal neoplasm, possibly a dysembryoplastic neuroepithelial tumor). | For cases diagnosed 2007 or later, this is a single primary. A single tumor is always a single primary. Assign histology code 9400/3 [Astrocytoma, low grade]. This diagnosis was not revised or amended based on the later surgery. It is possible that the malignant component was entirely removed during the first surgery. |

20071090 | Multiplicity Counter/Type of Multiple Tumors--Breast: How are these data items coded for a single breast primary composed of both in situ and invasive disease when measurements are provided for both the invasive and in insitu components? See Discussion. | Breast cancer, invasive duct carcinoma with DCIS, 1.3 cm, DCIS 3.7 cm. "The in situ carcinoma is very extensive in this lumpectomy. It is present contiguously from sides 1A through 1L sparing only the final 8 mm of medial margin. In situ and invasive carcinoma are prominently present along almost the entire superior margin." Is the mult counter 02 with Type of mult tumor 30, or one tumor? | Because there are individual measurements for each of these tumors, code the multiplicity counter 02 [Two tumors present]. Code Type of Multiple Tumor as 30 [In situ and invasive]. | 2007 |
|
20071131 | Cell indicator--Lymphoma: If the primary site for a lymphoma is stated to be the lymph nodes but there is no biopsy of a lymph node, can the immunophenotype designation for a lymphoma be coded based on a bone marrow or liver biopsy indicating "diffuse large B-cell lymphoma"? | For cases diagnosed prior to 1/1/2010: The cell indicator or immunophenotype designation for lymphomas may be coded from pathology reports on tissue from bone marrow or liver when there is no tissue from the primary site. Code information on cell type from any available source. See the Appendix C of the 2007 SEER manual, Coding Guidelines for Lymphomas, pages C-1055 to C-1056 for more information about coding this field for lymphomas. 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. |

20071106 | MP/H Rules--Bladder: Does rule M6 mean that any combination of tumors with the histologies 8050, 8120-8124, or 8130-8131 are the same primary regardless of the amount of time between tumor occurrences? See Discussion. |
Many interpret Rule M7 to mean when separate occurrences of TCC of the bladder are diagnosed more than 3 years apart, it is reportable as a second primary. However, doesn't Rule M6 mean that if the histology is any combination of 8050, 8120-8124 or 8130-8131 for tumors diagnosed more than 3 years apart, they are reported as a single primary? |
For cases diagnosed 2007 or later: Papillary, transitional cell and/or papillary transitional cell carcinomas of the bladder are a single primary using Rule M6. Rule M6 includes diagnoses within 3 years of each other AND diagnoses more than three years apart for the histologies listed. If rule M6 applies to your case, stop. Do not continue on to Rule M7. |

20071085 | CS Tumor Size/CS Extension--Prostate: Because prostatectomy results are excluded from the CS Extension field for prostate, is code 95 [No evidence of primary tumor] accurate to reflect bilateral lobe involvement of prostate cancer when it is incidentally found following a radical cystectomy for a bladder primary? Why must tumor size be 000 when the CS Extension code is 95? | 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 prostate CS Extension to 99 [Extension unknown] and code CS Tumor Size according to the information available from the surgery. CS Extension code 95 [No evidence of primary tumor] should be used only in that rare situation when the only evidence of disease is distant mets or lymph node involvement, no primary tumor found. That is why CS tumor Size must be 000 when CS Extension code 95 is used. |

20071063 | Reportability/Diagnostic Confirmation: If a diagnosis based solely on positive flow cytometry is reportable even if a bone marrow biopsy is negative, how is diagnostic confirmation coded? |
For cases diagnosed prior to 2010 The case is reportable if a recognized medical practitioner says the patient has cancer. A flow cytometry alone is not diagnostic but it may be supported by either a positive bone marrow or a clinician's statement. If the clinicians statement is based only on flow cytometry, code diagnostic confirmation to 8 [Clinical diagnosis only]. |
