20220042 | First Course Treatment/Radiation Therapy: How should Lutathera be coded? CoC states XRT- Radioisotopes and SEER states Other Treatment. |
Lutathera is a radioconjugate consisting of the tyrosine-containing somatostatin analog Tyr3-octreotate (TATE) conjugated with the bifunctional, macrocyclic chelating agent tetra-azacyclododecanetetra-acetic acid (DOTA) and radiolabeled with the beta-emitting radioisotope lutetium Lu 177 with potential antineoplastic activities. |
Update to the current manual: Code Lutathera as radiation (isotopes NOS code 13). We will make this change in the next version of the SEER manual. |

20220006 | Histology/Brain and CNS: How is histology coded for a 2021 diagnosis of “neuroepithelial tumor with PATZ1-EWSR1 fusion, not elsewhere classified” found during a right thalamic mass resection? See Discussion. |
Patient has a remote history of a right thalamic mass status-post two resections; reported as malignant oligodendroglioma (pathology not received) and chemo/radiation therapy, who recently presented with persistent headaches. Imaging revealed a 3.4 cm heterogeneous lobulated right thalamic mass with coarse calcifications and a probable cystic component. Pathologist indicates the histologic and immunophenotypic features of this neoplasm are that of relatively circumscribed neuroepithelial tumor without high grade features (mitotic activity, microvascular proliferation, necrosis). Molecularly this neoplasm is characterized by a PATZ1-EWSR1 fusion, which has recently been proposed to be a distinct neuroepithelial tumor entity with a broad histological spectrum. |
Assign 8000/1. Neuroepithelial tumor with PATZ1-EWSR1 fusion, not elsewhere classified, is not recognized as a distinct entity at this time. It is not listed in ICD-O-3.2 or in the 5th edition of the WHO CNS classification. |

20220043 | First Course Treatment/Neoadjuvant Therapy--Melanoma: How are the three Neoadjuvant Therapy data items (Neoadjuvant Therapy, Neoadjuvant Therapy--Clinical Response, Neoadjuvant Therapy--Treatment Effect) coded when a patient is diagnosed with melanoma in the lymph nodes with no primary skin site identified? The physician gives immunotherapy as neoadjuvant therapy with planned and carried out surgical resection of involved lymph nodes following completion of immunotherapy. There is no "planned definitive surgical resection of the primary site" as no primary site was found, |
Assign code 0 to each of the three Neoadjuvant Therapy data items in this situation. We will add an example to the coding instructions for these data items in the next release of the manual. |

Solid Tumor Rules/Histology--Bladder: How is histology coded for a transurethral resection of the bladder (TURB) diagnosis with multiple components? See Discussion. |
Examples: Bladder TURB: Invasive high grade urothelial carcinoma with poorly differentiated (40%), lipoid (5%), and sarcomatoid (55%) components. Bladder tumor base TURB: Invasive high grade urothelial carcinoma with poorly differentiated (65%) and sarcomatoid (30%) components. The Urinary Sites Solid Tumor Rules, histology coding rules, say to code the most specific histology or subtype/variant, regardless of whether it is described as majority, minority, or component. Poorly differentiated (8020) and sarcomatoid (8122) are both urothelial subtypes, but there is no rule to instruct how to code a tumor/tumors with multiple urothelial subtypes. |
Code histology as 8120/3 in the two examples using Note 1 in the Urinary Sites Solid Tumor Rules, instruction 1 of the Coding Histology section. The subtypes/variants or components must describe a carcinoma or sarcoma in order to code a histology described by those terms. |

20220007 | Histology: Is there any guidance on using STRATA Oncology testing (molecular tumor profiling tests), such as StrataNGS and StrataEXP, to code SSDIs, histology, etc? I do not see anything in STR, SEER Program Manual, SINQ, or CAnswerForum. We are seeing the testing with our 2021 paths. |
We recommend that you do not use information from these molecular tumor profiling tests until they become a standard diagnostic tool. If/when that happens, we will add information to the various manuals. |

20220026 | Solid Tumor Rules/Histology--Parotid: How is histology coded for a myoepithelial carcinoma ex-pleomorphic adenoma of the parotid? |
Patient has a 2021 left parotidectomy showing myoepithelial carcinoma ex-pleomorphic adenoma. Is this coded to myoepithelial carcinoma (8982/3) or carcinoma ex-pleomorphic adenoma (8941/3)? It is unclear how to arrive at the correct histology code using the current Solid Tumor Rules. |
Code myoepithelial carcinoma ex pleomorphic adenoma as carcinoma ex pleomorphic adenoma (CXPA) (8941/3) using Head and Neck Solid Tumor Rule H1 as this is a single histology. The WHO Classification of Head and Neck Tumors, 5th ed., describes CXPA as a rare epithelial and/or myoepithelial malignance arising in association with a primary or recurrent pleomorphic adenoma. The histologic type of the carcinoma component is usually recorded, in this case, myoepithelial carcinoma. |

20220036 | Solid Tumors Rules/Histology--Head and Neck: How is histology coded for head and neck primaries when a tumor is diagnosed as an invasive squamous cell carcinoma with multiple subtypes? See Discussion. |
Example Case 1: 2022 mobile tongue tumor biopsy shows squamous cell carcinoma, basaloid non-keratinizing type. Example Case 2: 2022 base of tongue mass biopsy shows squamous cell carcinoma, basaloid non-keratinizing type, p16 positive. Table 5, Note 2 (Head and Neck Equivalent Terms and Definitions) instructs us to code non-keratinizing squamous cell carcinoma which is p16 positive to 8085 (Squamous cell carcinoma HPV-positive), ignoring the non-keratinizing subtype. Does p16 or HPV positivity also take priority over multiple subtypes (basaloid non-keratinizing type)? |
Assign 8083/3, basaloid squamous cell carcinoma (BSCC), in both examples. It is more important to capture the variant than to code 8085 or 8086. WHO Classification of Head and Neck Tumors, 5th ed., states that BSCC is a distinctive form of SCC, characterized by prominent basaloid morphology, squamous differentiation, and aggressive behavior. Some primary sites capture p16 status as a Site Specific Data Item; you may record the p16 results when that is the case. |

20220002 | Solid Tumor Rules (2018, 2021)/Histology--Cervix: For cases diagnosed 1/1/2022 and later, how is histology coded for the following three cervix cases relating to p16? See Discussion. |
The 2022 SEER Manual indicates the p16 status (positive or negative) can be used to code more the specific histology for squamous cell carcinoma, human papilloma virus (HPV) positive (8085) and squamous cell carcinoma, HPV negative (8086). However, the histology coding instructions in the Other Sites schema have not been updated and the 2022 SEER Manual does not cover all situations commonly encountered in the registry. Does the clarification regarding p16 apply to these other situations?
|
For cases diagnosed beginning 1/1/2022, assign histology based on new codes and terms for the examples of cervical cancer using the available p16 results as follows. 1. Adenocarcinoma, HPV-independent, NOS (C53._) (8484/3) 2. Carcinoma, squamous cell, HPV-associated (C53._) (8085/3) 3. Carcinoma, squamous cell, HPV-independent (C53._) (8086/3) The 2022 SEER Manual states: Beginning with cases diagnosed 01/01/2022 forward, p16 test results can be used to code squamous cell carcinoma, HPV positive (8085) and squamous cell carcinoma, HPV negative (8086). Use the available results as the rules for Other Sites have not been updated yet. The SSDI Manual data item p16 for Cervix schema also states that p16 is based on testing results and not a physician statement. We can address these situations in a future version of the Solid Tumor Rules. The Other Sites rules will provide document priority when coding hsitology: biopsy vs. resection, cytology vs. histology, primary site vs. mets or regional site. |

20220003 | Reportability/Histology--Anus: Are 2021 diagnoses of anal intraepithelial neoplasia (AIN) II or AIN II-III reportable in patients with a known history of AIN II or AIN II-III diagnosed prior to 2021? See Discussion. |
Patient has a history of AIN I/low-grade squamous intraepithelial lesion (LSIL) dating back to at least 2015, was diagnosed with AIN II-III in 12/2019, and then diagnosed again with AIN II-III in 08/2021. There is no indication of treatment or a disease-free interval for this patient. SINQ 20210015, while not an exact match to this case, implies there is no clear disease-free interval for these AIN diagnoses, so it is the same non-reportable neoplasm diagnosed prior to reportability (12/2019). However, there was a diagnosis of a reportable neoplasm in 2021, so it also seems possible this would be accessioned as a reportable tumor based on a diagnosis of reportable tumor diagnosis in 2021. With the reportability changes for these intraepithelial neoplasia II/II-III tumors, these situations will arise more frequently. |
Report AIN II and AIN II-III cases when initially diagnosed in 2021 or later. Do not report retrospective cases; that is, cases with diagnoses prior to 2021 with continuation of AIN II or AIN II-III extending into the reportable period. |

20220014 | Surgery of Primary Site--Melanoma: How is Surgery of Primary Site coded when a path specimen is labeled as a “staged excision” for a cutaneous melanoma. See Discussion. |
Patient was diagnosed on biopsy with lentigo maligna melanoma of the nasal dorsum. The only available documentation of the subsequent surgery is a single pathology report with the nasal dorsum “staged excision (debulking specimen)” and four additional “staged excision” specimens of the same site. Is it safe to assume this is a Mohs surgery? Would it be safe to assume staged excisions of sites other than skin of face, are also Mohs surgery? |
Interpret a "staged excision" for cutaneous melanoma as a type of Mohs surgery. Skin surgery codes are currently under review and revision. Document details in available text fields. |
