20220047 | Solid Tumor Rules/Multiple Primaries--Head and Neck: Is a patient with 2020 neck mass, squamous cell carcinoma (SCC), p16-negative, who then had a biopsy of the right tonsil (C09.9) in July 2022, SCC p16-positive, one or two primaries? Is this coded to 8070/3 using pre-2022 rules or a new, second primary p16-positive, 8085/3. See Discussion. |
History provided by the oncologist Right neck mass since 2019; 04/07/20, initial biopsy p16-negative SCC, delay of treatment due to patient preference, agreed to biopsy of tonsil and work-up August 2022; right tonsil biopsy: p16-positive, G2 SCC, nodal mass at that time >6 cm with extensive extranodal extension, Stage III (cT2, cN3, cM0, p16-positive); based on this history, was staged as a tonsil primary and p16-positive. Patient details 1. March 2020, CT neck and chest revealed a 0.5 x 2.7 x 2.3 cm low-density necrotic nodal mass at right neck level 2 suspicious for metastatic disease. There was a slight asymmetric increased size of the right palatine tonsil. There are a few sub-4 mm pulmonary nodules which are nonspecific. 2. April 7, 2020, FNA of right neck mass with pathology revealed p16-negative SCC 3. April 20, 2020, PET/CT revealed 3 x 2 cm right-sided level 2 node with FDG avidity 4. May 5, 2020, flexible laryngoscopy showed no obvious primary lesion 5. May 2020, after evaluation by a medical oncology, patient declined any treatment 6. June 17, 2022, return visit in medical oncology after PET/CT demonstrates significant progression in the neck; patient definitively declines chemo, but would like surgical opinion. Now has more rapidly progressive disease with skin breakdown and weeping from malignant lesion right neck. 7. June 22, 2022, radiation oncology consultation 8. July 15, 2022, tonsil biopsy: Invasive squamous cell carcinoma, moderately differentiated with LVI, p16-positive 9. Patient now agreeing to treatment with radiation: Tooth extractions 8/30/2022, radiation planning 9/14/2022 10. Patient consulted with cancer specialist who explained surgery is not recommended given level of extranodal extension and risk of seventh cranial nerve paralysis and fistula formation with surgical excision and who recommended chemoradiation 11. September 9, 2022, patient presented for radiation CT simulation/treatment planning and informs treatment team. Patient declined/refuses concurrent chemotherapy despite recommendations from two cancer institutions. |
Abstract a single primary of the tonsil. The diagnosis date is March 2020 (the date of the CT scan). Assign 8070/3 for the histology. Metastases were found in 2020 before the primary of tonsil was determined in 2022. The oncologist information confirms this. |

20220009 | First Course Therapy/Reason for No Surgery of Primary Site: What code should be used for Reason for No Surgery of Primary Site in 2020 in situations affected by the pandemic when abstracting all sites? See Discussion. |
Example: Patient scheduled for left nephrectomy on 3/10/20 due to left renal papillary renal cell carcinoma diagnosed on 2/11/20 via needle core biopsy. Abstract indicated surgery was cancelled due to the pandemic. Abstract also indicated the surgery was not rescheduled. |
There is no available code that fits this situation. We recommend assigning code 6 (Surgery of the primary site was not performed; it was recommended by the patient’s physician, but was not performed as part of the first course of therapy. No reason was noted in patient record.) and documenting the situation in a text field. |

20220024 | Update to Current Manual/Residence at diagnosis: Would an exchange student be a temporary resident of the SEER area or a non-resident? See Discussion. |
A 17 year old exchange student was brought into the hospital with appendicitis. The patient had an appendectomy; there was no follow up treatment. 5/27/2006 pathology report of vermiform appendix: Adenocarcinoid appendix <5 mm tumor limited to appendix. The patient has no record in Lexis Nexus and no social security number. The address is a post office box; additionally, the patient’s birthplace is Switzerland and is lost to follow up. |
Code the residence where the student is living for exchange students temporarily living in the U.S. Code the temporary address if known or the Post Office Box if unknown. We will add this scenario to the next release of the SEER manual. |

20220001 | Solid Tumor Rules (2022)/Histology--Bladder: Can the term configuration be used to code the more specific histology for bladder primaries diagnosed 2022 and later? See Discussion. |
In the September 2021 Urinary Sites Solid Tumor Rules update, the term configuration was removed from the “DO NOT CODE histology when described as” list. However, it was not added as a term that can be used to code the more specific histology for urinary tumors. Can configuration be used to code the more specific histology 8130 (papillary urothelial carcinoma) when the diagnosis is urothelial carcinoma, tumor configuration: papillary? |
Beginning with cases diagnosed 1/1/2022, the term "configuration" can be used to code histology for urinary sites only. At the request of the AJCC urinary experts, the instructions were changed to allow configuration to be used to code histology. |

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. |

20220017 | Histology--Thyroid: What is the correct histology code for a thyroid resection showing papillary carcinoma, tall cell variant with oncocytic features with 30% of largest tumor (right) is tall cell variant and both foci contain benign multinucleated giant cells? See Discussion. |
There is an ICD-O histology code for papillary carcinoma, tall cell (8344/3) as well as papillary carcinoma, oxyphilic cell (8342/3). Per SINQ 20150045, the term oncocytic is synonymous with oxyphilic in this context. The term “variant” can be used for the Other Sites (non-updated STR sites) primaries when the ICD-O-3.2 (or ICD-O-3 for older cases) includes the term “variant” in the histology name. The MPH General Instructions did not include the term “variant” as a term that can be used to code histology. |
Code papillary carcinoma, tall cell variant with oncocytic features to papillary carcinoma, tall cell (C73.9) (8344/3). The WHO Classification of Endocrine Organs states that this variant is composed of cells that are as tall as they are wide, and show abundant eosinophilic (oncocytic-like) cytoplasm. Tall cells must account for greater than or equal to 30% of all tumor cells. |

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. |

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. |

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. |

20220033 | When coding the Covid testing results, does SEER have any guidance on whether or not at home tests fall within reportability? For instance, if a medical provider says pt tested positive on an at home test, do we record that? |
When you have information about home COVID tests, record this information. For example, if the home test was positive record as follows: COVID-19 rapid viral antigen test POS 08/09/2022 |
