20230015 | Solid Tumor Rules/Multiple Primaries: Should two 2021 diagnoses be abstracted as two primaries? The patient has a history of thyroid cancer in 2008 with no evidence of recurrence/progression. In 2021, two abstracts were submitted with a diagnosis of C809, poorly differentiated malignant neoplasm and a C421, myeloproliferative disorder. See Discussion. |
2021-Right pleural fluid: Negative for carcinoma. 5/18/2021: Right iliac crest bone marrow core biopsy, aspirate smear, clot section and peripheral blood smear: Hypercellular bone marrow, morphological findings are suspicious for a myeloproliferative neoplasm. Flow Cytometry: Slight immunophenotypic abnormalities of the myeloid cells. No abnormal B cell, T cell, or NK cell populations identified. Normal female karyotype. KARYOTYPE: 46,XX[20]. Negative for deletion of 13q14.3 (D13S319) by FISH. Negative for deletion of 13q34 (LAMP1) by FISH. Negative for hyperdiploidy involving chromosome 9 by FISH. Negative for t(9;22)(q34;q11.2) by FISH. Negative for deletion of the EGR1 gene on 5q31 by FISH. Negative for monosomy 5 by FISH. Negative for deletion of 7q31 by FISH. Negative for monosomy 7 by FISH. Negative for deletion of 20q12 by FISH. Negative for trisomy of chromosome 8 by FISH. 6/4/21-Left adrenal; biopsy: poorly-differentiated malignant neoplasm with extensive necrosis. Immunohistochemical stains show the neoplastic cells to be negative for CK7, TTF-1 and p63. Negative CK7 and TTF-1 would argue against a lung primary. Correlation with clinical and radiological findings is advised. We are unable to contact the provider. |
Based on the diagnosis date for the unknown primary, use the 2007 MPH Other sites rules. Since the site codes differ for each primary, rule M11 applies, abstract two primaries. |

20061128 | Marital Status: Is marital status coded to 2 [married] if the patient is legally married to a same-sex spouse (e.g., patient has a Canadian spouse and in Canada, same-sex marriages are legal)? | Code marital status for same-sex persons based on the legal status. For the case example above, assign code 2 [married]. | N/A | Marital Status | 2006 | |

20081047 | Reason no surgery of primary site/First course treatment: If the Reason no Surgery of Primary Site field is coded as 7 (refused), must the other treatment options (radiation, chemo, hormone) also be coded as 7? See Discussion. | Coding instruction #5 in the SEER manual states: "Assign code 7 (refused) if the patient refused recommended surgery or made a blanket statement that he/she refused all treatment." | Refused [code 7] means this modality was specifically recommended by the physician and the patient refused. If two treatment alternatives were offered and surgery was refused, code Reason no surgery of primary site 1 [Surgery of the primary site was not performed because it was not part of the planned first-course treatment]. Refusal of surgery does not necessarily mean that all treatment was refused. Coding Surgery of Primary Site as "refused" does not affect the coding of Radiation, Chemotherapy, Hormone Therapy, etc. |

20061054 | First Course Treatment/Chemotherapy: Is adriamycin used in a chemoembolization procedure coded as chemotherapy? | Code as chemotherapy only when a chemotherapeutic agent is used, such as adriamycin. Do not automatically code chemoembolization as chemotherapy. | N/A | Chemotherapy, First course treatment | 2006 | |

20081050 | MP/H Rules--Fallopian Tube: How many primaries are to be abstracted for a case in which a bilateral fallopian tube primary is staged T1c by the pathologist? See Discussion. | A bilateral fallopian tube primary was coded to multiple primaries. However, the AJCC staging for T1b says, "tumor limited to both tubes" and T1c "tumor limited to one or both tubes." The tumor is T1c according to the pathologist. Is this two T1c primaries or one? |
For cases diagnosed 2007 or later, abstract as two primaries using Other Sites rule M8. This issue will be reviewed during the next update to the MP/H rules. |

20021010 | Histology (Pre-2007): What code is used to represent the histology adenocarcinoma with "areas of" papillary architecture and "foci of" squamous differentiation? Even though "areas of" and "foci" are non-majority terms, should histology be coded to the combination code of adenocarcinoma with mixed subtypes [8255/3]? |
For tumors diagnosed prior to 2007: Code the Histology field to the majority of the tumor, which is 8140/3 [adenocarcinoma, NOS]. The terms "areas of" and "foci of" should be ignored because they are not terms that reflect the majority of the tumor. Therefore, we cannot use rule A on page 2 of Coding Complex Morphologic Diagnoses because this diagnosis does not represent a complex morphology. 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. |

20010084 | EOD-Size of Primary Tumor: Can you code the known size of the residual tumor in a further resected specimen if the size of the tumor in a prior excisional biopsy is unknown? See discussion. | Excisional biopsy is done prior to admission and the tumor size is unknown. Pt is admitted for a mastectomy and the residual tumor size is 5 mm. | For cases diagnosed between 1998-2003:
Code the EOD-Size of Primary Tumor field to 999 [unknown]. The majority of the tumor would have been removed during excisional biopsy and it is possible that the tumor could have been quite large. |

20031171 | Reportability: Is pseudomyxoma peritonei always reportable? See Description. | In the ICD-O-3, pseudomyxoma peritonei has a behavior code of 6, indicating that it is malignant. Does this imply that pseudomyxoma peritonei is always a reportable malignancy? In the past, our pathologist consultant told us that pseudomyxoma peritonei is only a reportable malignancy if the underlying tumor is malignant. A benign cystadenoma of the appendix, for example, can rupture causing pseudomyxoma perionei. Does SEER agree with our pathologist consultant? Example: Patient was found to have psuedomyxoma peritonei. Right hemicolectomy was done. Path reported an appendix with mucinous cystic tumor of undetermined malignant potential. A definite diagnosis of cancer can not be rendered. |
Reportability is determined from the behavior of the primary tumor and the behavior of implants. If either are malignant, the case is reportable. The case example does not seem to be reportable, based on the available information. Cancer diagnosis has not been made according to the pathology report. |

20031147 | Reason No Cancer-Directed Surgery--Hematopoietic, NOS: Is this field always coded to 1 [not performed, not part of first course] for leukemias & other hematopoietic diseases? | For cases diagnosed 2003 and later: For sites where "Surgery of the primary site" is coded 00 or 98 (hematopoietic included), Reason for No Surgery of Primary Site should be coded as 1 [Surgery of the primary site not performed because it was not part of the planned first course of treatment]. On rare occasions, there may be surgery to the primary site for a hematopoietic disease, such as an excisional biopsy of a myeloid sarcoma. Refer to the "Abstracting and Coding Guide for the Hematopoietic Diseases" for cell-type-specific treatment information. | N/A | Reason no treatment | 2003 | |

|
20081081 | Reportability: If a dermatopathologist refers to an atypical fibroxanthoma as a malignant process, but the ICD-O-3 indicates it is a borderline process, is this a reportable case? See Discussion. | "Final Diagnosis: Surface of ulcerated histologically malignant spindle cell neoplasm, consistent with atypical fibroxanthoma. Note: An exhaustive immunohistochemical work-up shows no melanocytic, epithelial or vascular differentiation. Atypical fibroxanthoma is a superficial form of a malignant fibrous histiocytoma." | The pathologist has the final say on behavior. In this case, the pathologist states that this tumor is malignant in the final diagnosis. Therefore, this case is reportable. | N/A | N/A | 2008 |
