20220034 | First Course Treatment--Lymphoma: Is the first round of systemic therapy coded as first course of therapy or is it all the therapy given to achieve remission for a lymphoma case with multiple treatments? See Discussion. |
Lymphoma case diagnosed in 2021: The patient had first round of systemic therapy as documented in the treatment plan and a post-chemotherapy PET scan that showed residual disease. The patient then had a different combination of systemic therapy and still had some residual disease. The patient was given a third round of different combination of systemic therapy in preparation for stem cell transplant. According to the physician post-stem cell transplant note, the patient achieved complete remission. Is the first course of therapy the first round of systemic therapy only or is it all the therapy given to achieve remission? It seems like only the first round of systemic therapy is first course of therapy for both leukemia and lymphoma in the hematopoietic manual. I thought all treatment for all hematopoietic cases was first course until remission achieved or progression was evident. |
Code all treatments the patient received as first course of treatment. For lymphoma and leukemia, first course of treatment may include first-line, second-line, consolidation, maintenance, salvage, etc., any treatment to achieve remission. We have added this to the agenda for the 2024 updates to the Hematopoietic Manual and Database. |

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. |

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. |

20220040 | Laterality--Brain and CNS: Can Laterality be coded as 5 (midline) for a sella turcica meningioma (or tuberculum sellae meningioma) when no other statement regarding tumor laterality is documented? See Discussion. |
Laterality is often not noted for these sella turcica meningiomas; therefore, Laterality is often coded as 9 (Unknown). Because the sella turcica appears to be a midline structure in the base of the skull, is Laterality code 5 (midline) more appropriate when additional information is unavailable? |
You may assign code 5 (Paired site: midline tumor) for laterality of a meningioma of the sella turcica (C700). The 2022 SEER manual states in Laterality coding instruction 5: Assign Laterality code 5 only when the primary site is C700, C710-C714, C722-C725, C443, C445. Do not assign code 5 to sites not listed in 5.a. Note that code 9 is for paired sites and there is no information concerning laterality. Document laterality information in the appropriate text field. Note: Laterality does not factor into the CNS Solid Tumor rules. |

20220030 | Histology--Lung: Is it acceptable to code histology as 8042/3 for a 2020 lung primary when the pathology report states only "oat cell carcinoma?" See Discussion. |
In the old 2007 Multiple Primaries/Histology rules, Lung Equivalent Terms and Definitions section, oat cell carcinoma (8042) was listed as one of the obsolete terms that was no longer recognized for small cell carcinoma. That note is not in the current 2018 Solid Tumor Manual lung chapter, and ICDO-3.2 lists oat cell carcinoma as the preferred term for code 8042/3. Would rule H4, Note 2 apply -- only one histology present, if not listed in Table 3 use ICD-O and all updates, to code oat cell carcinoma as 8042/3? |
While oat cell carcinoma is an outdated term, if that is all the pathology report states, code histology as 8042/3. Yes, Rule H4 applies: the diagnosis was a single histology. H4 instructs you to refer to the solid tumor H table, and if the term is not found there, check ICD-O and ICD-O updates. All possible histologic types that could occur in the lung may not be included in the table. |

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. |

20230019 | Solid Tumor Rules/Multiple Primaries--Pancreas: How many primaries, and what M Rule applies, when a pancreatectomy identified an invasive adenocarcinoma in one pancreatic head tumor, but multiple separate pancreatic neuroendocrine tumors (PanNETs), WHO grade 1, in the pancreatic body? See Discussion. |
There was a 3.5 cm invasive adenocarcinoma tumor in the pancreatic head. There were four separate, sized pancreatic neuroendocrine tumors measuring 0.9, 0.7, 0.5 and 0.2 cm in the pancreatic body. There are multiple tumors with distinctly different histologies. However, Table 11 (Pancreas Histologies) does not include any entries for neuroendocrine tumors of the pancreas (e.g., pancreatic NET, WHO grade 1, histology 8240). While it would seem Rule M19 should apply as they’re distinctly different histologies, because PanNETs are not included in Table 11, it is not clear which M Rule applies to these multiple tumors. If Rule M19 does not apply, we are left with Rule M21 (Abstract a single primary when there are multiple tumors that do not meet any of the above criteria). Are these separate tumors with distinctly different histologies really a single primary? Pancreatic neuroendocrine tumors are not an uncommon histology, is there a reason these were not included in Table 11? |
Abstract two primaries using the 2023 Solid Tumor Rules, Other Sites, Rule M19, as adenocarcinoma and pancreatic neuroendocrine tumors are two distinct histologies. The WHO Classification of Digestive Tumors, 5th ed., Chapter 10-Tumors of the Pancreas, lists both epithelial tumors and neuroendocrine neoplasm as separate entities. The Solid Tumor Rules histology-specific tables contain histologies that commonly occur in the 19 site-specific histology tables; therefore, not all histologies are listed in the rules. Further, the adenocarcinoma would be staged in the Pancreas Schema, while the neuroendocrine tumor would be staged in the NET Pancreas schema. We will consider adding PanNETs to Table 11 in a future release of the Solid Tumor Rules. |

20230008 | SEER Manual/Surgery of Primary Site 2023--Breast: What instructions should be followed when the 2023 SEER Manual Appendix C 2023 Breast Surgery Codes advise to code 1 in Surgical Procedure of Other Site for a simple bilateral mastectomy but the 2023 STORE Manual does not. See Discussion. |
The 2023 SEER Manual, Appendix C 2023 Breast Surgery Codes, note reads: SEER Note: Assign code A760 for a more extensive bilateral mastectomy. Assign code 0 in Surgical Procedure of Other Site (NAACCR #1294). For a simple bilateral mastectomy, assign code A410 with code 1 in Surgical Procedure of Other Site (NAACCR #1294). In the 2023 STORE Manual, these notes are not mentioned and we are instructed not to code surgery to other site. Other education related to 2023 breast coding provided by NAACCR states to not code surgery to other site. |
Assign code 1 in Surgical Procedure of Other Site (NAACCR #1294) when a simple bilateral mastectomy is performed for a single tumor involving both breasts. This statement was inadvertently omitted from the STORE manual and will be added back in: For single primaries only, code removal of contralateral breast under the data item Surgical Procedure/Other Site (NAACCR Item #1294) or Surgical Procedure/Other Site at This Facility (NAACCR Item #674). The information presented by NAACCR was intended to be consistent with what is in the SEER manual. It may have been misuderstood. |

20230013 | Reportability/Histology--Skin: Is dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous overgrowth, DFSP with fibrosarcomatous component Grade 2, or DFSP with focal myxoid features (2022) reportable for 2021-2022 diagnoses? |
Yes. DFSP with fibrosarcomatous overgrowth and DFSP with fibrosarcomatous component Grade 2 are synonymous with fibrosarcomatous DFSP (8832/3). Our expert pathologist also advises that DFSP with focal myxoid features is the same as DFSP, myxoid (8832/3). |

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. |
