20140039 | Reportability--Heme & Lymphoid Neoplasms: Is a statement of "JAK-2 positive polycythemia" reportable? See discussion. |
Polycythemia, NOS is not reportable. However, there is a statement in the Heme Manual Glossary for JAK2 that states, "When JAK2 is positive, the MPN is definitely reportable." Does a positive JAK 2 always mean there is a reportable myeloproliferative disorder or must there also be an associated statement of a reportable neoplasm (e.g., myeloproliferative disorder, polycythemia vera, or essential thrombocythemia)? |
A positive JAK 2 does not always mean there is a reportable myeloproliferative disorder. There must also be an associated statement of a reportable neoplasm (e.g., myeloproliferative disorder, polycythemia vera, or essential thrombocythemia). The glossary entry will be clarified. |

20081040 | Reportability/Histology--Hematopoietic: If a JAK2 positive myeloproliferative disorder is reportable, how should histology be coded? | Please discuss the significance of JAK2 point mutation. Example: Bone marrow biopsy showed hypercellular marrow with increased megakaryocytes associated with JAK2 point mutation consistent with myeloproliferative syndrome. Path comment: While the morphologic changes would be compatible with a myeloproliferative syndrome, they are not specific for this as similar findings can be seen in reactive conditions. However, a molecular diagnostic test demonstrated a positive JAK2 point mutation which would support the diagnosis of myeloproliferative syndrome. In summary, the combined histologic and molecular diagnostic findings support a myeloproliferative syndrome. The differential diagnosis would be between polycythemia vera and essential thrombocythemia. Subsequent clinical diagnosis: polycythemia vera. |
For cases diagnosed prior to 1/1/2010:Follow the instructions in the SEER manual on pages 1-4 to determine reportability. Code the histology using all information available for the case. If the clinician reviews the case and states a particular histology based on his/her review, code that histology. The clinician has access to all of the information available for this case. He/she uses his/her expertise to form a clinical diagnosis. 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. |

20150022 | Grade--Bladder: Do you use the grade stated on the pathology report for coding the grade/differentiation field for bladder and renal pelvis field? See discussion. |
Please confirm correct coding for grade for papillary urothelial carcinoma of the bladder/renal pelvis and urothelial carcinoma of the bladder/renal pelvis. SEER Manual 2014 and 2015 state: "Do not use these tables to code grade for any other groups including WHO (CNS tumors), WHO/ISUP (bladder, renal pelvis), or FIGO (female gynecologic sites) grades." They also state "In transitional cell carcinoma for bladder, the terminology high grade TCC and low grade TCC are coded in the two-grade system" in the Grade section. These statements are not included in SEER Manuals prior to 2014. |
Use the grade stated on the pathology report to code grade/differentiation for bladder and renal pelvis field unless the grade is stated to be WHO/ISUP grade. |

20240045 | Reportability/Ambiguous Terminology--Prostate: Should cases be reported and abstracted based on ambiguous terminology, e.g., suspicious for prostate cancer, when the physician is not treating the case as malignant? See Discussion. |
Please comment on these specific scenarios.
|
For each of your scenarios, the medical record information indicates that the case is not reportable based on physician opinion. Do not abstract these cases. Remember that the ambiguous terms list is to be used as a last resort. The ideal way to approach abstracting situations when the medical record is not clear is to follow up with the physician. If the physician is not available, the medical record, and any other pertinent reports (e.g., pathology, etc.) should be read closely for the required information. See page 19 in the SEER Manual, https://seer.cancer.gov/manuals/2024/SPCSM_2024_MainDoc.pdf |

20200078 | Solid Tumor Rules (2018)/Histology--Brain and CNS: Should the new malignant term pituitary blastoma be added to Table 3 of the 2018 Malignant Central Nervous System (CNS) and Peripheral Nerves Solid Tumor Rules? See Discussion. |
Pituitary blastoma was not added to Table 3 (Specific Histologies, NOS, and Subtypes/Variants) of the 2018 Malignant CNS and Peripheral Nerves Solid Tumor Rules as part of the December 2020 update. This is a new malignant CNS histology for 2021 and later. Not including this histology in Table 3 results in the registrars being required to check another source to correctly code this histology. If this histology cannot be used for cases diagnosed prior to 2021, should that diagnosis year clarification be included in the STR? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
The Solid Tumor Malignant CNS tables do not list pituitary specific histologies at this time. Registrars will need to refer to ICD-O and/or updates until the decision to add malignant pituitary neoplasms is made. Pituitary blastoma is a rare tumor which occurs in children. |

20130211 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a bone marrow shows low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia? See Discussion. | Physician note: Bone marrow shows 10% involvement with low grade lymphoma. Assessment: Low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia.
The multiple primaries calculator indicates two primaries are to be reported. However, the physician stated that Waldenstrom's macroglobulinemia is another name for this patient's lymphoma.
There were no enlarged lymph nodes seen on the CT scan. The proposed treatment for this patient is Rituxan for the macroglobulinemia. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M2, this is a single primary because there is a single histology. The bone marrow initially showed a non-specific B-cell lymphoma. WM is a type of B-cell neoplasm. After immunophenotyping, a more specific histologic diagnosis of WM was made. In this case a single histology (WM) is diagnosed by the definitive diagnostic method (serum paraprotein demonstrating IgM), so it accessioned as a single primary.
Per PH16, code the histology to 9761/3 [Waldenstrom Macroglobulinemia (WM)] and the primary site to C420 [blood].

20130183 | Reportability--Heme & Lymphoid Neoplasms: Is a peripheral blood finding consistent with involvement by monoclonal, lambda-restricted mature B cell population with co-expression of CD5 and CD23 reportable if, immunophenotypically, the case is consistent with a chronic lymphocytic leukemia/small lymphocytic lymphoma? See Discussion. |
Peripheral blood: Final diagnosis: Leukocytosis absolute lymphocytosis monoclonal, lambda restricted B-cell population w/co-expression of CD5 and CD23 absolute increase in CD4=helper T cells. See comment. Comment: Peripheral blood findings are consistent with involvement by monoclonal, lambda-restricted mature B cell population with co-expression of CD5 and CD23, which is immunophenotypically consistent with a chronic lymphocytic leukemia/small lymphocytic lymphoma immunophenotype. However, the absolute monoclonal population is only 3.02k/ul. According to WHO criteria, in the absence of extramedullary tissue involvement, the monoclonal lymphocyte population must be greater than or equal to 5.0 k/ul. Therefore, in the absence of clinical evidence of extramedullary tissue involvement, the diagnosis is most consistent with a monoclonal B cell lymphocytosis. Review of initial analysis reveals well-defined groups of cells within lymphocyte, monocyte and granulocyte gates as defined by CD45 and sid-scatter characteristics (%'s are listed). Overall, peripheral blood findings are consistent with involvement by monoclonal, lambada-restricted B cell population with a chronic lymphocytic leukemia/small lymphocytic lymphoma immunophenotype. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case is reportable. Code histology to 9823/3 [CLL/SLL]. Ambiguous terminology is used to accession cases (determine reportability) because it has been used for over 30 years to do so. Any deviation from using ambiguous terminology to determine case reportability would cause the reporting of incidence counts to vary. In this case, there was a reportable, ambiguous terminology diagnosis on peripheral blood that is "consistent with" involvement by chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) immunophenotype. The ambiguous terminology "consistent with" in the flow cytometry report is acceptable to determine reportability. Given that it is the only reportable histology mentioned in the scenario, it is also used to code histology. The instruction "Do not code histology based on ambiguous terminology" is intended to be used when there is a reportable NOS histology and reportable more specific histology stated in the diagnosis. Ambiguous terminology cannot be used to report the more specific diagnosis in cases of Heme & Lymphoid neoplasms. SEER*Educate provides training on how to use the Heme Manual and DB.

20200017 | Histology--Head & Neck: Why is 8070 not listed as a valid histology for ill-defined sites as squamous cell carcinoma arises in the head and neck sites. See Discussion. |
Per the site validation list: https://seer.cancer.gov/icd-o-3/sitetype.icdo3.20190618.pdf#search=site%20validation, ill-defined sites (ILL-DEFINED C760-C768) does not include 8070- Squamous cell carcinoma as a valid histology. Therefore when a Cervical Lymph Node and Unknown Primary Tumor of the Head and Neck is submitted with a C760 and 8070/3, it requires an override be set. |
Histology code 8070 has been added to C760 on the site validation list. It will be updated for 2021. Continue to override this combination for now. |

20130176 | Reportability--Ovary: Is an adult granulosa cell tumor of the right adnexa reportable if the left adnexa, diaphragm and paratubal tissue are reported to be consistent with metastasis? See discussion. |
Per the pathology report: Right adnexa: adult granulosa cell tumor. Left adnexa: Foci of metastatic granulosa cell tumor in paratubal tissue. Diaphragm smears: consistent with metastatic granulosa cell tumor. Comment: The morphology and immunoprofile of the cellular aggregates in the paratubal soft tissue are consistent with metastatic granulosa cell tumor. |
Based on the information provided, this case of adult granulosa cell tumor is malignant and reportable. According to our expert pathologist consultant, "though granulosa cell tumor NOS/ adult NOS is 8620/1, the presence of peritoneal implants or metastases, and/or lymph node metastases indicates the tumor is malignant, and it should be coded /3."
Note that the presence of implants or metastases does not indicate malignancy in the case of low malignant potential ovarian epithelial tumors. Our path expert explains "in contrast, by convention the behavior of borderline/LMP ovarian epithelial tumors is determined by the ovarian primary, and is /1, even though there may be peritoneal implants/metastases, or metastatic disease in lymph nodes. The treatment may vary in these circumstances, but to my knowledge the decision as to the tumor designation remains based on the primary tumor." |

20150026 | First course treatment--Breast: When Lupron is given as cancer-directed treatment for metastatic breast cancer, should it be coded as Hormone Therapy or Other Therapy? See Discussion. |
Per the SEER*Rx Database, Lupron is coded as Other Therapy for breast cancer until such time that it receives FDA approval. However, SINQ 20021042 states Lupron should be coded as Hormone Therapy when given as cancer-directed therapy. These two sources contradict each other.
Information regarding hormone therapy for breast cancer in both the SEER*Rx Database and the National Cancer Institute's Cancer Topics website (http://www.cancer.gov/types/breast/breast-hormone-therapy-fact-sheet) seem to indicate that the SINQ answer is the correct choice. The NCI Cancer Topics website states that Lupron acts to block ovarian function and is an example of an ovarian suppression drug that has been approved by the FDA. The SEER*Rx Database Remarks section states that a combination of letrozole and leuprolide (Lupron) "is considered standard treatment for metastatic breast cancer and is sometimes used for treatment of early stage breast cancer." But the Remarks go on to state that Lupron should be coded as Other Therapy until it receives FDA approval.
It is unclear how to code Lupron for breast cancers when the NCI website indicates that it is standard treatment while the SEER*Rx Database states both that it is and that it is not standard treatment. |
Code Lupron given for breast cancer in the "Other" treatment field using code 6 (other-unproven). Lupron is still not an approved hormone treatment for breast cancer and should not be coded in the hormone field.
