20031077 | Histology (Pre-2007)--Lung: What code is used to represent the histology "mucin-producing bronchoalveolar carcinoma?" Is mucin-producing synonymous with mucinous? | For tumors diagnosed prior to 2007:
Code histology as 8253 [Bronchiolo-alveolar carcinoma, mucinous]. Mucin-producing bronchoalveolar carcinoma is best classified in ICD-O-3 as Bronchiolo-alveolar carcinoma, mucinous.
For tumors diagnosed 2007 or later, 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. |

20031079 | Primary Site: Should we code C80.9 [unknown primary] or code C34.9 [Lung] according to the terminology, "most likely site of origin is lung"? See Description. | We have a case of metastatic keratinizing squamous cell ca. The work-up shows small densities in the lung that may represent inflammatory or chronic changes. No other imaging that shows origin. Physical exam states 2 months of left axillary mass. H/O SCCA of the skin involving chest wall. Path reads: Metastatic w/d keratinizing SCCA. This lesion almost undoubtedly represents mets. The most likely site of origin is lung followed by esophageal primary or head & neck. The final discharge states, "Metastatic SCCA to Left Axilla". |
Code the primary site according to the physicians' opinion, especially the treatment decision. If the physician treats the patient for a lung primary, code primary site as lung. If the primary site cannot be determined, code C80.9. According to the pathologist, the most likely primary site for the example above is lung. The final discharge diagnosis does not reflect the pathologist's opinion, and does not contradict it either. If there is no conflicting medical opinion, code primary site to C34.9 [lung]. |

20031206 | EOD-Extension: How is this field coded for synchronous primaries when metastatic disease is found and there is no statement to indicate which primary is the source of the metastases? See Description. | Patient was diagnosed with both esophageal and pancreatic cancer. Liver metastases were also identified. The source of the liver mets is unknown. | For cases diagnosed 1998-2003: Search the record for information about the source of the metastasis. If no such information can be found, code the metastasis to both primaries. Update the abstracts when information becomes available confirming the primary site responsible for the metastasis. Assuming the liver metastases in the example above are distant (i.e. not contiguous) code extension as 85 [Metastasis]. | 2003 |

20031031 | Reportability/Histology--Hematopoietic, NOS: What histology code is used for a patient diagnosed with "myelodysplasia" prior to 2001, if a bone marrow biopsy in 2002 is consistent with myelodysplastic syndrome with refractory anemia with bilineage dysplasia with excess blasts and the final impression is "myelodysplastic syndrome slowly evolving toward acute leukemia?" |
Patient was admitted in July 15, 2002. Per the H&P, patient was diagnosed 5 years ago with myelodysplasia. Patient had bone marrow biopsy about 5 years ago and then again on 6-10-02. Patient has become transfusion dependent since mid-March. Bone marrow on 6-10-02 was consistent with myelodysplastic syndrome with refractory anemia with bilineage dysplasia with excessive blasts. Impression: Myelodysplastic syndrome slowly evolving toward acute leukemia. Plan: start chemo. 7-16-02 bone marrow biopsy showed acute myeloid leukemia. Can we assume that the myelodysplasia diagnosed 5 years ago was refractory anemia and therefore, patient's first reportable diagnosis would be the AML? Or is the 6-10-02 bone marrow biopsy showing refractory anemia to be the first reportable diagnosis because the term "myelodysplasia" is non-specific? |
For cases diagnosed prior to 1/1/2010: Based on the information provided, the diagnosis date is June 2002. The diagnosis is 9895/3, acute myeloid leukemia with multilineage dysplasia (AML with prior myelodysplastic syndrome). According to the SEER table of hematopoietic diseases, refractory anemia and myelodysplastic syndrome followed by AML is one primary. Prior to 2001, a diagnosis of myelodysplasia was not reportable. For cases diagnosed 2010 forward, 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. |

20031033 | Grade, Differentiation--Hematopoietic: Is this field coded to 6 [B-cell] from a flow cytometry that specifies the percentage of B-cells that exist within the percentage of lymphoid cells in the bone marrow biopsy? See Description. | Bone marrow biopsy, Final path diagnosis: consistent with small lymphocytic lymphoma/chronic lymphocytic leukemia. Comment: flow cytometry analysis was performed on bone marrow aspirate. The gated population of lymphoid cells comprises approximately 19% of total nucleated cells. Of these, 53% are B-cells which express CD19, CD22. These findings are consistent with the above diagnosis. | For cases diagnosed prior to 1/1/2010:Yes, assign code 6, B-cell. The flow cytometry analysis confirms B-cell. For cases diagnosed 2010 forward, 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. |

20031140 | Primary site--Unknown & ill-defined site/Kidney: How should this field be coded when humeral metastases are compatible with renal cell carcinoma pathologically, no kidney lesion is found clinically and the physician's signout diagnosis is "no primary found, as of now unknown"? See Description. | Path states "biopsy of humerus, mets sarcomatoid carcinoma consistent with renal cell carcinoma." Material was sent to Mayo Clinic for consult & they state "with focus of clear cells, agree that a likely primary is renal cell carcinoma." Abdominal CT showed no abnormality in kidneys. When the registrar abstracted the case she spoke to the managing physician who told her that "no specific site was found and it was, as of now, unknown." This was stated about three months after dx. Can we code as a renal primary based on pathologic information or should we code unknown based on CT and physician's statement? | Code this case to C64.9 [Kidney, NOS]. ICD-O-3 rule H states that the topography code attached to a morphology term may be used when the topographic site is not given in the diagnosis. Topography code C64.9 is attached to morphology code 8312/3 [Renal cell carcinoma] in ICD-O-3. |

20031131 | Multiple Primaries (Pre-2007): Would osteosarcoma of the right arm diagnosed four years after malignant fibrous histiocytoma, also in the right arm, be a second primary when the physician states, "the patient's disease progressed to sarcoma after radiation was administered?" |
For tumors diagnosed prior to 2007: The osteosarcoma is a second primary. The first three digits of the histology codes are different: 8830 [Malignant fibrous histiocytoma] and 918_ or 919_ [Osteosarcoma]. In addition, the diagnoses are four years apart. According to SEER rules, these are separate primaries. For tumors diagnosed 2007 or later, 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. |

20031155 | CS Site Specific Factor--Prostate: Does perineural invasion affect the coding of SSF3, pathologic extension? See Description. | "Adenoca scattered over a 2.5 cm region bilaterally toward the apex. Perineural invasion is identified, including within the right apex." Does this mean that there is extension into the apex? | 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 cases diagnosed 2004 and forward: Presence or absence of perineural invasion does not affect pathologic extension. Most likely perineural invasion is still localized. It means that there is tumor found along the track of the nerves in the prostate. Where the nerves enter the prostate, the capsule is thinner than in other areas; thus pathologists make note of the potential for extracapsular extension. The CAP Cancer Protocol for Prostate states that perineural invasion "has been associated with a high risk of extraprostatic extension...although the exact prognostic significance remains to be determined." Based on the available information, code the case example to 023 [Involves both lobes]. |

20031153 | Laterality/Multiple Primaries (Pre-2007)--Ovary: Are ovarian primaries with bilateral involvement always coded to laterality 4 (bilateral)? See Description. | Example: "Right ovary with mass replacing majority of ovarian tissue consistent with serous adenoca. Lt ovary with foci of adenoca." No specific statement of primary. Can we assume that the malignancy originated in the right ovary since it is more extensively involved or should laterality be coded 4 because both ovaries have tumor? | For tumors diagnosed prior to 2007:
If one ovary is listed as the primary site, code laterality to that ovary. The example above is one of those times when you would code to the single ovary. The issue of one or both ovaries being involved is handled in staging.
Abstract the example above as a single primary with code 1 [Right] for laterality.
For tumors diagnosed 2007 or later, 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. |

20031125 | Histology/Reportability/Behavior Code--Testis: Is a mature teratoma that is metastatic to lymph nodes reportable? See Description. |
Pathology report states, "Histologic sections reveal lymph node metastases, consisting predominantly of mature teratoma. In addition, there are cells scattered through the fibrous stroma which exhibit mild cytologic atypia but have low N:C ratios. The largest metastasis grossly measures 10cm. In addition extracapsular extension is identified. Diagnosis: Lymph Nodes--Metastatic Testicular Carcinoma Involving Multiple Lymph Nodes." The morphology code for mature teratoma is 9080/0. The pathologist does not classify this as an immature teratoma (9080/3). Is this reportable? |
Yes, this metastatic teratoma is reportable. This is a malignant teratoma by virtue of the lymph node metastases. Code the histology as 9080/3 [Teratoma, malignant, NOS]. Primary site is testis [C62_]. |
