20230058 | Solid Tumor Rules/Multiple Primaries--Breast: How many primaries should be accessioned for a patient with known history of right breast carcinoma in 2018 followed by 2022 biopsy proven right and left breast invasive ductal carcinoma if the physician states this is a right breast primary with widespread metastasis including the left breast? See Discussion. |
The patient was initially diagnosed with invasive mammary carcinoma of the right breast in 2018, treated with lumpectomy, sentinel node biopsy, radiation, and hormones. Hormones were discontinued early due to dysfunctional uterine bleeding. |
This is a single primary according to the Solid Tumor Rules.

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. |

20220027 | Reportability/Heme & Lymphoid Neoplasms--CNS: Is ALK-positive histiocytosis, primary site Central Nervous System (CNS), reportable, and is the correct histology code 9750/3? See Discussion. |
2022 case: Surgical Pathology Report-spinal cord tumor, biopsies: ALK-positive neoplasm most consistent with ALK-positive histiocytosis. |
Report this 2022 case of ALK-positive histiocytosis using histology code 9751/3, Langerhans cell histiocytosis, disseminated. Use text fields to document that this is a case of ALK-positive histiocytosis. This term may be assigned a new code once the 5th edition of the Hematopoietic WHO Blue Book is released. |

20220018 | Solid Tumor Rules/Histology--Thyroid: What is the correct histology code for the following thyroid primary with multiple tumors abstracted as one primary diagnosed prior to 2021? See Discussion. |
2016 Total thyroidectomy, Multifocal -Dominant Tumor: Right Lobe, Papillary thyroid carcinoma (8260/3) -Tumors two through five: Three tumors Papillary thyroid carcinoma (8260/3), and one tumor Papillary thyroid carcinoma, follicular variant (8340/3) -An additional tumor: Non-invasive follicular thyroid neoplasm with papillary-like nuclear features (8343/2) |
Code this multifocal thyroid carcinoma, single primary, as papillary thyroid carcinoma, follicular variant (8340/3) using Solid Tumor Rules, Other Sites, Rule H13 that says to code the most specific histologic term. We consulted with our endocrine specialty pathologist and when there is a mix of papillary and follicular variants, assign 8340. Non-invasive follicular thyroid neoplasm with papillary-like nuclear features is coded as 8349/1 beginning in 2021. According to the WHO Classification of Endocrine Organs, 4th edition, it was formerly classified as non-invasive encapsulated follicular variant of PTC (FVPTC) (8343/2) but was reclassified based on extremely low malignant potential. |

20220010 | EOD 2018/Heme & Lymphoid Neoplasms--Myeloid Sarcoma: How is Extent of Disease (EOD) Primary Tumor coded for a myeloid sarcoma with multifocal skin involvement? See Discussion. |
Patient has a diagnosis of myeloid sarcoma presenting as multiple erythematous papules and nodules on back, chest, right arm & shoulder. Oncologist did not mention any evidence or suspicion of an associated AML diagnosis. HemeRetic schema EOD Primary Tumor Note 1 states that myeloid sarcoma can be coded as localized (code 100) or systemic (code 700). It is not clear what would qualify as systemic disease for myeloid sarcoma. |
Assign code 100, localized, using the 2018 EOD Primary Tumor, HemeRetic schema, for the myeloid sarcoma with skin involvement since only the skin is involved. Use code 700, distant or disseminated, when multiple organs are involved. |

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. |

20220025 | Reportability/Histology--Anal Canal: For cases diagnosed in 2021, is anal intraepithelial neoplasia (AIN) II reportable? There is conflicting information regarding the reportability for AIN II. SINQ 20210048 says to report AIN II but the 2021 SEER Manual Appendix E states intraepithelial neoplasia (8077/2 and 8148/2) must be unequivocally stated as grade III to be reportable. |
AIN II is reportable for 2021. Squamous intraepithelial neoplasia, grade II is listed in ICD-O-3.2 as 8077/2 making it reportable for cases diagnosed in 2021. AIN is a type of squamous intraepithelial neoplasia. The wording in Appendix E of the 2021 SEER manual (must be unequivocally stated as grade III to be reportable) was left over from earlier versions and is not correct for 2021 diagnoses. Follow the guidance in SINQ 20210048. |

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. |

20220031 | Tumor Size/Neoadjuvant Treatment: If a patient discontinues neoadjuvant therapy and then has surgery, how is the pathologic tumor size coded with the pathologic tumor size greater than the clinical tumor size? Currently, we are instructed to code 999 for the pathologic tumor size when neoadjuvant therapy is given; what happens when neoadjuvant chemotherapy is discontinued after 3 cycles (plan for 4 cycles)? |
Assign 999 for pathologic tumor size when patient has received neoadjuvant therapy, even when neo-adjuvant therapy is not completed. Describe the details in text fields. |

|
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. |
