20071076 | MP/H Rules/Histology--Thyroid: Regarding rule H15, is the mixed code 8340 [Papillary carcinoma, follicular variant] used when there are subtypes of these histologies described, such as a tumor diagnosed with follicular and papillary microcarcinoma or should 8341 [Papillary microcarcinoma] be used? | For cases diagnosed 2007 or later: For coding purposes, this is a papillary and follicular combination that would be coded to the combination code 8340/3 [Papillary carcinoma, follicular variant].
For thyroid cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult, usually less than 1 cm. in diameter. |

20071061 | Histology--Melanoma: How is a "malignant melanoma arising in a melanocytic nevus" coded? | The histology code is 8720/3 [malignant melanoma, NOS]. There is no specific code for melanoma arising in melanocytic nevus. According to our pathologist consultant, this is likely because nevi are so common, melanoma arising in association with them is common and appears to have no bearing on prognosis or treatment. Most pathologists do not include the nevus in the diagnosis of melanoma, even when they see it. Code melanomas arising in melanocytic nevi to the appropriate melanoma code, probably 8720, 8721, or 8743 in most cases. |

20071072 | Ambiguous Terminology/Date of Conclusive Terminology: If there is an unknown date of diagnosis, should the Ambiguous Terminology field always be coded to 9 and the Date of Conclusive Terminology be coded to 99999999? See Discussion. | Scenario: Mammogram is suspicious for carcinoma, unknown date in 2007. A biopsy prior to admission to reporting facility is positive for carcinoma. Patient seen at reporting facility in June 2007 for treatment. | The purpose of the data item "Ambiguous Terminology" is to flag cases entered into the registry based on a diagnosis with ambiguous terminology. Because the case above was entered into the registry based on conclusive terminology, code Ambiguous Terminology to 0 [Conclusive term] and code Date of Conclusive Terminology to 88888888 [not applicable]. | 2007 |
|
20071067 | CS Extension/Histology (Pre-2007)--Bladder: Is the histology coded to 8010/2 [carcinoma in situ] or to 8130/2 [papillary transitional cell carcinoma, non-invasive] for a 2006 bladder tumor with a final path diagnosis of "mixed non-invasive papillary TCC and flat carcinoma in-situ" and is CS Extension coded to 01 [Papillary transitional cell carcinoma state to be noninvasive]or to 06 [Carcinoma in situ]? See Discussion. | If the correct code for histology is 8130/2 and CS Extension is 06, this combination does not pass NAACCR edits. | 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.For tumors diagnosed prior to 2007, code CS Extension to 06 and histology to 8130/2. Override the NAACCR edit.
For cases diagnosed 2007-2014, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

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. |

20071098 | Multiplicity Counter/Date of Multiple Tumors/CS Tumor Size--Lung: How are these fields to be coded when work-up of a malignancy spans a couple of months and reveals developing nodules? See Discussion. | Example: Chest CT on 4-26-07 reveals 2.2 cm mass in lingula, left lung, consistent with lung malignancy. Biopsy on 5-18-07 shows non-small cell carcinoma. PET scan on 6-6-07 shows left upper lobe mass consistent with known non-small cell lung carcinoma. Second developing mass increasing in prominence since 4-07 in periphery of left upper lobe, approximately 3.6 cm which may represent intrapulmonary mets or second primary neoplasm. At least 3 additional intrapulmonary nodules have developed since 4-07, two in the left upper lobe and one in the right upper lobe, suspicious for mets. | 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.Multiplicity Counter/Date of Multiple Tumors Apply the multiple primary rules first and record the number of tumors determined to be a single primary in Multiplicity Counter. Record the corresponding date in Date of Multiple Tumors. These data items may be updated once if future tumors are determined to be the same primary as the initial diagnosis.
CS Tumor Size Include information gathered through
WHICHEVER IS LONGER. Metastasis known to have developed after the diagnosis was established should be excluded. |

20071074 | MP/H Rules/Multiple Primaries--Lung: How many primaries should be reported when an "adenocarcinoma" is discovered in one of several new nodules at the scar in a lung and it is less than a year after a wedge resection for a diagnosis of "bronchioalveolar adenocarcinoma" in the same lung? See Discussion. | In March 2006 patient diagnosed with bronchioalveolar adenocarcinoma [8250/3] and had wedge resection. In November 2006 a CT chest shows nodules at the scar suspicious for recurrence. In January, 2007, there was a biopsy of one of the nodules showing adenocarcinoma [8140/3]. Is this part of the original disease process diagnosed in March 2006 or should it be abstracted as a new primary based on 2007 MP/H rules (histology is different at the first 3 digits)? |
For cases diagnosed 2007 or later:
Try to obtain more information/clarification on the 2007 diagnosis -- for example, is it metastasis? Based only on the information provided for this case, the 2007 diagnosis is a separate primary. Use the 2007 MP/H rules to assess the 2007 diagnosis. Begin with rule M3 in the multiple tumors section. Stop at rule M11, multiple primaries. |

20071025 | Radiation Therapy: How is radiation coded when it is "recommended" but the patient dies before radiation is started? See Discussion. | Code 0 seems appropriate but then we would lose the fact that it had been recommended. All of the other modalities give an option for 'recommended but patient died prior to treatment.' Is there a reason this option is not given for radiation? | Code Radiation (Rx Summ--Radiation) to 0 [None; diagnosed at autopsy].
SEER does not collect the Reason For No Radiation field. However, those who abstract using software that captures this data item can identify these cases. Code 5 [radiation not administered because patient died] reflects this situation.
Radiation (Rx Summ-Radiation) is a SEER field. This field is derived from the data collected in Rad-Boost Rx Modality and Rad-Regional TX Modality. These fields do not include a choice for "radiation not given because the patient died prior to treatment." Therefore, this information cannot be coded in the Radiation field. |

20071114 | Ambiguous Terminology/Date of Diagnosis: How would you code the diagnosis date when the body of an imaging report uses reportable ambiguous terminology while the final impression in that same report uses non-reportable ambiguous terminology? Would you code the diagnosis date to the date of the scan or to the subsequent biopsy date that confirmed a malignancy? See Discussion. | Within the body of a mammogram report, the radiologist stated, "diffuse inflammatory tissue throughout the rt breast w/ large rt axillary lymph nodes, consistent with an inflammatory carcinoma of rt breast." His final impression, however, said "extremely suspicious rt breast w/ extremely dense breast parenchyma and adenopathy in axilla, suggesting an inflammatory carcinoma." The patient then went on to have a biopsy, which was indeed positive for cancer. | Accept the reportable ambiguous terminology from the body of the mammogram. Record the date of the mammogram as the date of diagnosis. The guidelines on page 4 of the 2007 SEER manual addressing discrepancies within the medical record can be applied to discrepancies within one report. The instructions are: If one section of the medical record(s) uses a reportable term such as apparently and another section of the medical record(s) uses a term that is not on the reportable list, accept the reportable term and accession the case. |

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. |
