20230047 | Reportability/Histology--Head & Neck: Is a 2023 mandibular biopsy showing “severe squamous dysplasia with microscopic focus suspicious for superficial invasion” reportable? See Discussion. |
Patient had a mandibular mucosal lesion resected in June of 2023, with a diagnosis of “atypical squamous proliferation” and case was forwarded to an expert in oral pathology for best classification. Subsequent slide review final diagnosis was “moderate to severe squamous dysplasia.” That slide review diagnosis goes on to state “microscopic focus suspicious for superficial invasion.” Currently there is no ICD-O code for severe squamous dysplasia, however it is unclear if this terminology is equivalent to high grade squamous dysplasia (histology code 8077/2). |
Report as squamous cell carcinoma (8070/3) on the basis of “microscopic focus suspicious for superficial invasion.” "Severe dysplasia" is equivalent to "high grade dysplasia" in the Head and neck. As such, "severe squamous dysplasia" would be coded to 8077/2. However, in combination with the statement of "with microscopic focus suspicious for superficial invasion,” report as squamous cell carcinoma (8070/3) based on “microscopic focus suspicious for superficial invasion.” The 2023 SEER Manual instructs us to code the behavior as malignant (/3) if any portion of the primary tumor is invasive no matter how limited, i.e., microinvasion. Use text fields to record the details. |

20230046 | Reportability/Histology--Tongue: Is high grade squamous dysplasia of the tongue reportable; and is it the same as carcinoma in situ (CIS), code 8077/2? |
High grade squamous dysplasia of the tongue is reportable as of 2021 and later as 8077/2. |

20230041 | Solid Tumor Rules/Multiple Primaries--Breast: Is an in situ tumor followed by an invasive tumor a single or multiple primaries? See Discussion. |
In the examples below, are these a single or multiple primaries? Example 1: Tumor 1: C509/left breast, 8520/2 (in situ lobular carcinoma), dx date-01/10/2019 Tumor 2: C509/ left breast, 8500/3 (carcinoma NST), dx date-08/19/2021 Example 2: Tumor 1: C509, right breast, 8520/2, dx date 06/26/2014 Tumor 2: C508, right breast, 8500/3, dx date-05/23/2019 There seems to be some conflicting info on this. In the 2020 Breast Rules there was a note add to the revision history. “M10 Same behavior requirement re-added.” Which is not in the rules now, nor was it noted to the revision changes in the last two change logs. Inquiry 20200070 would seem to indicate that this is multiple primaries, but that contrasts with 20230010 which would seem to indicate a single primary, and an ASK A SEER Registrar question that we received a response to. I don’t see a scenario where rule M17, an invasive tumor DX more than 60 days after an in situ tumor would come into play. If behavior no longer applies to rule M10, at what point did that change get made? Please advise. |
Abstract a single primary when there are multiple tumors of carcinoma NST/duct and lobular using the current Breast Solid Tumor Rules, Rule M10, May 2023 Update, for cases diagnosed 01/01/2018 and forward in the examples provided. The rule also notes to follow the H rules to determine the correct histology code when a mixture of behaviors is present in carcinoma, NST and lobular carcinoma. Rule M5 does not apply as the timeframe is less than 5 years in both examples. The 2023 update for the Breast Solid Tumor Rules (released November 2022) states: The rules for determining single versus multiple primaries in tumors with carcinoma NST/duct and lobular carcinoma have been revised and now align with ICD-O-3.2. Applicable Histology Rules have also been revised to reflect ICD-O-3.2 histology terminology and corresponding ICD-O codes. |

20230045 | Reportability/Histology--Thyroid: Is a diagnosis of “angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma” reportable if the diagnosis comment states, additional immunostains were performed which demonstrate the carcinoma cells are positive for thyroglobulin and negative for calcitonin? See Discussion. |
Patient had a right thyroid lobectomy on 12/2022, with initial diagnosis of “thyroid carcinoma pending expert consultation for definitive classification.” The slide review documented in the addendum shows a final diagnosis of “Angioinvasive oncocytic thyroid neoplasm, see comment.” The subsequent comment states, “I would classify this lesion as an angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma.” The comment goes on to state, “Additional immunostains were performed which demonstrate the carcinoma cells are positive for thyroglobulin and negative for calcitonin. The diagnosis remains unchanged.” |
Do not report angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma based on the final, unchanged diagnosis. Worrisome is not a reportable ambiguous terminology. |

20230020 | First Course Treatment/Reason for No Surgery of Primary Site: How should Reason for No Surgery of Primary Site be coded for cases when surgery was planned but aborted due to extent of disease seen during planned procedure? See Discussion. |
Lung abnormality on imaging prompted diagnosis on subsequent biopsy and clinical staging was documented as cT1b N0 M0. There was an attempt at resection, but the patient was found to have chest wall involvement and the procedure was aborted. How would Reason for No Surgery of Primary Site be coded in these types of scenarios when the surgery is aborted and the treatment plan changes due to the extension seen during surgery? |
For the example provided: For 2023 cases and forward, if no part of the surgery was performed, code Surgery of Primary Site 2023 (NAACCR Item #1291) as code A000 or B000 (no surgical procedure of the primary site). Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 2 (surgery of the primary site was not recommended/performed because it was contraindicated due to patient risk factors (comorbid conditions, advanced age, progression of tumor prior to planned surgery, etc.). In contrast, if any part of the surgery was performed, assign the Surgery of Primary Site 2023 (NAACCR Item #1291) code that best reflects the extent of the surgery performed. Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 0 (surgery of the primary site was performed). Use text fields to record the details. For cases prior to 2023, apply the same approach using Surgery of Primary Site (NAACCR Item #1290) instead of Surgery of Primary Site 2023 (NAACCR Item #1291). |

20230069 | First Course Treatment/Immunotherapy--Colon: Is infliximab cancer directed treatment? See Discussion. |
While SEER*Rx does indicate infliximab should be coded as biological response modifier (BRM)/Immunotherapy, the manufacturer website for this medication indicates it is given for: Crohn’s disease, ulcerative colitis, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. In addition, SEER*Rx does not indicate which primary sites this treatment may be given for. If it is indeed cancer directed treatment, can the typical primary sites be added for clarity? Case example: Patient is diagnosed with colorectal cancer and also has an existing diagnosis of Crohn’s disease; received surgery and FOLFOX6, as well as infliximab. There was no statement of what disease the infliximab was given to treat. |
infliximab is not cancer-directed treatment. This drug was last updated by the FDA 2/22/2023 with additional information on its approval to treat non-malignant neoplasms. To date, the FDA has not approved it for use in colon cancer. This drug was intially developed to treat colon cancer; however, found to be ineffective treating cancer. |

20230025 | Histology--Cervix: Can human papilloma virus (HPV) or p16 testing results from a non-reportable high-grade squamous intraepithelial lesion (HSIL)/cervical intraepithelial neoplasia (CIN 3) pathology report be used to code histology as squamous cell carcinoma (SCC), HPV-positive (8085), if subsequent excision/resection identifies invasive SCC and no further HPV or p16 testing is done on the invasive specimen? See Discussion. |
Example #1: Cervix loop electrocautery excision procedure (LEEP) pathology: Histologic Type: Squamous cell carcinoma, HPV-associated. Histologic Type Comments: High-risk HPV testing on previous Pap test sample reported as positive for high-risk HPV. The prior Pap diagnosis was HSIL only with molecular results positive for high-risk HPV. Example #2: Cervix endocervical curettage and biopsy with CIN 3, p16 diffusely positive. Subsequent LEEP with superficially invasive squamous carcinoma (no HPV or p16 testing done). This was followed by an additional cone excision that was negative for residual malignancy and p16 testing was also negative. |
Use the histology codes SCC, HPV-associated (8085/3) and SCC, HPV-independent (8086/3) only when HPV testing is done on that specimen. Do not use previous HPV tests to code the histology. Code as SCC, NOS (8070/3) in both examples as no HPV testing was performed on the LEEP procedure specimens that identified the SCC. |

20230063 | EOD 2018/EOD Regional Nodes--Melanoma: Can central cancer registries code Extent of Disease (EOD) Regional Nodes as 000 based on Breslow’s depth and/or Clark’s Level (per EOD and/or Summary Stage) from a melanoma pathology only report with a localized tumor and no information on regional lymph nodes or mets. See Discussion. |
Based on the EOD General instructions for accessible sites, the following three requirements must be met a. There is no mention of regional lymph node involvement in the physical examination, pre-treatment diagnostic testing, or surgical exploration; b. The patient has localized disease; c. The patient receives what would be the standard treatment to the primary site (treatment appropriate to the stage of disease as determined by the physician), or patient is offered usual treatment but refuses it. As a central registry, we receive a lot of melanoma path reports but never receive an abstract since the patients are seen at a dermatology office that does not report to the central registry. In these scenarios, we have both the diagnosis and wide excision or Mohs surgery from which we create a consolidated record. It is not often that lymph nodes are removed which indicates there were no palpable nodes. Since the Breslow’s and Clark’s level allow for summary staging, is it possible to have central registry guidelines that allow for coding lymph nodes other than 999? The path reports meet two of the three criteria. Is there any new literature that supports coding lymph nodes 000 based on a Clark’s level or Breslow measure providing the patient has a wide excision? |
Assign 000 for EOD Regional Nodes when you have a pathology only report with a localized tumor based on Breslow’s depth and/or Clark’s Level (per EOD and/or Summary Stage) and no information on regional lymph nodes or mets. When the tumor is noted to be regional or distant based on Breslow’s Depth and/or Clark’s based on the definitions in EOD and/or Summary Stage, do not assume that the nodes are negative and assign 999. Clarification will be added to the EOD manual. |

20230049 | Update to Current Manual/Surgery of Primary Site 2023--Skin: Regarding the 2023 skin surgery codes for punch biopsy NOS (B220) and shave biopsy NOS (B230), how is Date of First Surgical Procedure coded for cutaneous lymphoma and Kaposi sarcoma when the punch or shave biopsy is not excisional? See Discussion. |
Now that there are specific surgery codes for shave and punch biopsies, are these biopsies always the Date of First Surgical Procedure (NAACCR Item #1200)? Or should we still be applying the Surgery of Primary Site 2023 instruction in the SEER Manual that states shave or punch biopsies are most often diagnostic; code as a surgical procedure only when the entire tumor is removed and margins are free/gross disease is removed? We are aware of the instruction for melanoma cases outlined in SINQ 20230034; however, it is unclear if this should also apply to cutaneous lymphomas and Kaposi sarcomas, or if the intent of the procedure is used for these specific types of skin cases that typically present with multifocal involvement. Example 1: Patient is diagnosed March 2023 with primary cutaneous T-cell lymphoma presenting as pink, tan patches on the trunk. Punch biopsy diagnosed CTCL and treatment was given via narrow band UVB phototherapy. Example 2: Patient is diagnosed February 2023 with Kaposi sarcoma presenting as widespread violaceous macules, papules, plaques on the torso, bilateral extremities, and abdomen. Punch biopsy diagnosed Kaposi sarcoma. |
Code the Date of First Surgical Procedure (NAACCR Item #1200) as the date the shave, punch, or elliptical biopsy was performed. This instruction applies to cutaneous lymphoma and Kaposi sarcoma as well. Beginning with cases diagnosed 2023 and after, shave, punch, or elliptical biopsies are coded as a surgical procedure regardless of margin status. The instruction in the 2023 SEER Manual that states "shave or punch biopsies are most often diagnostic; code as a surgical procedure only when the entire tumor is removed and margins are free/gross disease is removed" has been deleted from the 2024 SEER Manual. Refer also to the Appendix C Coding Guidelines for Kaposi Sarcoma of All Sites and Lymphoma for coding primary site. |

20230074 | Extent of Disease/EOD Regional Nodes--Small Intestine: For an ileal/jejunal neuroendocrine primary, how should mesenteric soft tissue deposits (less than 2 cm) be collected in Extent of Disease (EOD) Staging? See Discussion. |
Example: Patient is diagnosed with grade 1 well-differentiated neuroendocrine tumor of the ileum, confirmed on ileocolic resection in 2023. The final diagnosis is a 2.8 cm ileal mass, with focal lymph-vascular invasion and a single 0.6 cm tumor deposit within mesenteric fat; primary tumor completely resected with widely negative margins and 10 regional nodes negative for malignancy. According to AJCC, mesenteric masses less than 2 cm should be stated in the pathology report as being present and collected by registrars but do not affect stage. EOD Regional Nodes has a code for large mesenteric masses greater than 2 cm only. How should we record these smaller tumor deposits if they are not supposed to affect stage? |
Do not code 500 for involvement of the mesentery unless the mesentery is specifically stated to be involved (and we don't have that information). We need more information on this case to assign EOD primary tumor. EOD Regional Nodes would be 000 per AJCC. |
