20230014 | Reportability--Thyroid: Is a case with thyroid fine needle aspirate (FNA) cytology with nodule 1 Bethesda category 5 and nodule 2 Bethesda 6, reportable in 2021? Does the Bethesda category 5 or 6 have any bearing on reportability? |
In the absence of information to the contrary, thyroid FNAs designated as Bethesda classification category VI are reportable. Thyroid FNAs designated as Bethesda classification category V are not reportable unless there is additional information confirming a reportable diagnosis. For both Bethesda V and VI, NCCN Guidelines recommend total thyroidectomy or lobectomy (depending on tumor size and nodal involvement) for the purposes of definitive diagnosis/treatment, so additional information should be available. We will add this to the next version of the SEER manual. In your example, nodule 1 Bethesda V is not reportable. Nodule 2 Bethesda VI is reportable. |

20230054 | Reportability/Histology--Pancreas: According to SINQ 20140058, solid pseudopapillary neoplasm of the pancreas is reportable (as of 2014). However, per ICD-O-3.2, this histology is not reportable until 2021+. Please clarify which is correct and clearly state the timeframe that it was reportable or not reportable. |
Solid pseudopapillary neoplasm of the pancreas is reportable for cases diagnosed in 2014 and later. Report solid pseudopapillary neoplasm of the pancreas (8452/3) as the guidance in SINQ 20140058 is still in effect. The 4th and 5th editions of the WHO Classification of Tumors of the digestive system define solid pseudopapillary neoplasm of the pancreas as a low-grade malignant pancreatic tumor. |

20230039 | Histology/Hematopoietic and Lymphoid Neoplasms--AML: What is the histology code for Acute Myelogenous Leukemia (AML) with monocytic differentiation, 9891/3: acute monoblastic and monocytic leukemia or 9867/3: Acute myelomonocytic leukemia? |
Code AML with monocytic differentiation as acute myeloid leukemia, NOS (9861/3) per consultation with our expert hematopathologist. Acute monoblastic and monocytic leukemia (9891/3) and acute myelomonocytic leukemia (9867/3) are distinct entities according to the WHO. "AML with monocytic differentiation" is a descriptive diagnosis, whereas, "Acute monoblastic and monocytic leukemia" are specific diagnoses. In the WHO Classification of Tumours, Central nervous system tumours (4th Ed) in 2016, WHO began integrating information on molecular alterations that provide significant prognostic implications and/or a therapeutic target into the histology code/term itself. As a result it is also important to look at the molecular testing because acute myeloid leukemias can have different molecular mutations that could result in coding to a different histology code. In this case, there was no other information regarding additional immunophenotyping, so that is why AML, NOS was assigned. Acute myeloid leukemia with monocytic differentiation has been added to the Hematopoietic and Lymphoid Neoplasm Database as an alternate name for 9861/3. |

20230059 | Histology--Heme and Lymphoid Neoplasms: How is histology coded for a diagnosis stated as MDS/AML (myelodysplastic syndrome/acute myeloid leukemia) per the international consensus classification (ICC)? See Discussion. |
The final diagnosis on bone marrow biopsy was high grade myeloid stem cell neoplasm, 17% blasts by differential count. The pathologist further states that this could be classified as “MDS with increased blasts (MDS-IB2) per the WHO 5th edition classification, or MDS/AML per the international consensus classification (ICC).” FISH and cytogenetics revealed a loss of 7q, but no other AML-related genetic abnormalities. The physician confirms the patient has MDS/AML. |
Updated Answer July 2024 Code histology as myelodysplastic neoplasm with increased blasts (9983/3) based on the WHO Classification of Hematolymphoid Tumors, 5th edition, Beta version 2. WHO lists MDS with increased blasts-2 (MDS-IB2) as a subtype of 9983/3. Terms coded to 9983/3 include
When differences exist between WHO and ICC, assign the histology based on the WHO Classification. |

20230040 | First Course Treatment/Hormone Therapy--Prostate: Is Lupron first course therapy in a patient who initially elected active surveillance for prostate cancer and then consented to treatment with Lupron? See Discussion. |
in March, the patient with stage cT1c, Gleason grade 7, prostate cancer elected active surveillance. In April, the patient consented to treatment with Lupron. There was no evidence of disease progression. According to the rules on page 161 of the 2023 SEER manual, we think the answer is yes, but the reporting hospital states that this is second course therapy. |
Code Lupron as second course therapy and code active surveillance as first course therapy in this scenario. The 2023 SEER Manual states to code all treatment data items to 0 or 00 (Not done) when the physician opts for active surveillance, deferred therapy, expectant management, or watchful waiting. Assign code 2 to Treatment Status. Active surveillance is not the same as "refusing treatment." Active surveillance is a valid option offered to the patient. The patient chose this option and later changed their mind. This is not a refusal of recommended treatment. Document all the details in the appropriate treatment text fields. |

20230079 | Solid Tumor Rules/Histology--Cutaneous Melanoma: How is histology coded for a 2023 diagnosis of “early lentiginous melanoma in situ” of the skin? See Discussion. |
Previous SINQ 20091100 has a similar scenario and the instruction was to code as lentigo maligna (8742/2); however, it does not appear to be applicable to cases diagnosed after 2020. The WHO Blue Book does not list melanoma, lentiginous type or lentiginous melanoma in situ as an alternate term for lentigo maligna and neither do the STR or the ICD-O-3.2. |
Assign code 8742/2 (lentigo maligna) for “early lentiginous melanoma in situ.” ICD-O-3.2 lists the preferred term for 8742/2 as lentigo maligna (C44._). |

20230021 | Histology--Soft Tissue: How is histology coded for malignant neoplasm with neuroectodermal differentiation and TPR-NTRK1 gene rearrangement diagnosed on left shoulder excision? See Discussion. |
March 2022, left shoulder soft tissue mass excision shows a spindle cell tumor with outside consultation diagnosis of malignant neoplasm with neuroectodermal differentiation and TPR-NTRK1 gene rearrangement. Diagnosis comments indicate the findings most closely resemble the spectrum of kinase-rearranged mesenchymal neoplasms, such as lipofibromatosis-like neural tumor. However, the expression of SOX10 and mature melanocytic markers is unusual, and does not exclude melanocytic differentiation. Should this be classified as a peripheral neuroectodermal tumor (9364) or as an "NTRK-rearranged spindle cell neoplasm (emerging)" (8990) if there is a NTRK gene rearrangement? |
NTRK-rearranged spindle cell neoplasm is a newly identified variant of sarcoma; however, WHO has not yet proposed a specific ICD-O code for this rare neoplasm. Code to spindle cell sarcoma (8801/3). WHO defines NTRK-rearranged spindle cell neoplasm as an emerging group of molecularly defined rare soft tissue tumors that span a wide group of morphologies and histological grades, and are most often characterized by a spindle cell phenotype among other characteristics. |

20230067 | First Course Treatment/Scope of Regional Lymph Node Surgery--Breast: How is Scope of Regional Lymph Node Surgery coded when initially there is a sentinel lymph node biopsy (SLNBx) and an intramammary node removed followed a month later by an axillary dissection for a right breast primary? See Discussion. |
Patient has a diagnosis of invasive carcinoma of the right breast from a core biopsy on 04/2023. Subsequent bilateral mastectomy and sentinel node biopsy proves one positive sentinel node and one negative intramammary node. One month later there is a completion axillary node dissection with 15 nodes negative for malignancy. Per previous SINQ 20190074, the initial mastectomy and sentinel node excision with intramammary node removal should be coded as Scope of Regional Lymph Node Surgery 6. It is unclear how the resulting axillary dissection should be recorded in Scope of Regional Lymph Node Surgery. There is no code for sentinel node biopsy and 3, 4, or 5 at same time (code 6) PLUS an additional subsequent axillary dissection. Please provide coding instructions for Sentinel Lymph Nodes Positive, Sentinel Lymph Nodes Examined, and Scope of Regional Lymph Node Surgery in this scenario. |
Scope of Regional Lymph Node Surgery: Assign code 7, Sentinel node biopsy and code 3, 4, or 5 at different times. In this case, the SLNBx (code 2) preceded the regional node dissection (code 5: 4 or more regional lymph nodes removed), i.e., procedures performed in separate surgical events. Sentinel Lymph Nodes Examined: Assign code 98, Sentinel lymph nodes were biopsied, but the number is unknown. In this case, only the results were provided. Sentinel Lymph Nodes Positive: Assign code 01, Sentinel nodes are positive (code exact number of nodes positive). In this case, there was one positive sentinel node. |

20230018 | SEER Manual/First Course Treatment--Chemotherapy: Does the First Course of Treatment end when subcategories change for treatments such as hormone therapy or immunotherapy or is that instruction specific to chemotherapy? See Discussion. |
Treatment for estrogen receptor positive (ER+) breast cancer started with tamoxifen (non-steroidal estrogen subcategory) and switched to letrozole (non-steroidal aromatase inhibitor subcategory). Patient being treated with immunotherapy, Avastin (cytostatic agent-antiangiogenesis agent subcategory), and then changed to Atezolizumab (monoclonal antibody subcategory). Is Atezolizumab a new course of therapy because it is a different subcategory? |
A change in the subcategory for a hormone drug does not indicate the end of First Course of Treatment because different hormone therapies generally achieve the same result. For example, some forms of breast cancer are estrogen-dependent and the various subcategories of hormone drugs used to treat them, such as gonadotropin-releasing factor agonists, aromatase inhibitors and estrogen antagonists, all achieve the same result - to block estradiol effects in these tumors. Similarly, a change in immunotherapy is not a new course of treatment. The instruction in the SEER Manual is specific to chemotherapy. Chemotherapy is the only systemic treatment for which a change in the subcategory of a drug indicates the end of First Course of Treatment, due to the fact that different chemical agents damage cancer cells in different ways and at different phases in the cell cycle. |
