20230006 | SEER Manual/First Course Treatment--Hematologic Transplant And Endocrine Procedures: How are Surgery of Primary Site and the Hematologic Transplant And Endocrine Procedures data items coded when patient has total abdominal hysterectomy and bilateral oophorectomy for an endometrial primary during the same procedure? Also, how would these data items be coded for a vaginal primary in a surgical scenario? See Discussion. |
The 2023 SEER Manual instructions contain a new note in Hematologic Transplant And Endocrine Procedure, Coding Instruction 6, regarding bilateral salpingo-oophorectomy (BSO) when performed for hormonal effect for breast, endometrial, vaginal, and other primary cancers. While we have observed BSO being performed for breast primaries, we do not recall ever seeing a statement for endometrial or vaginal primaries regarding a “BSO being done as hormonal manipulation” when scheduled either with or without a hysterectomy being performed simultaneously. As a result, we are not clear exactly when a BSO would be captured in the Hematologic Transplant And Endocrine Procedure field for these gynecologic primary sites. Also, if these types of procedures are Hematologic Transplant And Endocrine Procedures, are they also captured and coded in the Surgery of Primary Site codes that directly relate to those same organs? Does timing have any effect on the coding of either field? |
For a primary endometrial or ovarian cancer, record the oophorectomy/BSO procedure using the appropriate Surgery of Primary Site code that includes oophorectomy/BSO when done as part of first course of treatment (surgical resection). If performed for hormone effect, also record in the Hematologic Transplant and Endocrine Procedures data item. For other primary sites whose Surgery of Primary Site codes do not include oophorectomy/BSO, record it in the Hematologic Transplant and Endocrine Procedures data item when performed for hormone effect. Document information in the appropriate text fields. Candidates for risk-reducing BSO may include those with hereditary syndromes (such as BRCA mutations) or genes that carry a substantially increased lifetime risk of ovarian malignancy or hormone-sensitive cancers including estrogen-dependent cancers, like breast cancer, ovarian cancer and endometrial (uterine) cancer that rely on estrogen to develop and grow. |

20230051 | First Course Treatment/Surgical Margins of the Primary Site--Melanoma: Is margin status positive or negative when the lesion “approximates” margins? This was noted in the pathology report comment on a malignant melanoma in-situ shave biopsy. Follow-up with physicians is not possible in this situation. |
Assign margin status as “positive” when stated as approximates margins as recommended by our expert pathologists. Approximating means coming right up to inked margin without the margin transecting the tumor. |

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). |

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). |

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. |

20230027 | Solid Tumor Rules/Multiple Primaries--Peripheral Nerves: How many primaries should be abstracted, and which M Rule applies, when a malignant peripheral nerve sheath tumor (MPNST) in the right arm (C471) is followed greater than one year later by a separate malignant peripheral nerve sheath tumor of the thoracic chest wall (C473)? See Discussion. |
Since the peripheral nerves are included in the Malignant CNS schema of the Solid Tumor Rules, neither the differences in subsite nor timing indicate these are separate primaries (Rule M10 indicates a single primary). However, these are separate MPNSTs in different sites and the tumors are not stated to be metastasis. Additionally, these are treated as separate primaries by the managing physician. While the malignant CNS tumors do not take timing into account, is this correct for these peripheral nerve tumors that are often treated similarly to soft tissue tumors? Should Rule M8 be updated to include tumors in different peripheral nerve subsites? |
Abstract a single primary using Solid Tumor Rules, Malignant CNS and Peripheral Nerves, Rule M10 based on the information provided. Rule M10 applies as both non-contiguous tumors are of the same histology; i.e., on the same row in Table 3. As MPNST can arise in many sites, look for information about the precise location and tissue type in which the tumor arose. For example, if the tumors are stated to arise in soft tissue, follow the Multiple Primary Rules for Other Sites. Both WHO Classification of Central Nervous System Tumors and WHO Classification of Soft Tissue and Bone Tumors state that MPNST is a malignant spindle cell tumor often arising from a peripheral nerve, from a pre-existing benign nerve sheath tumor, or in a patient with neurofibromatosis type 1 (NF1). Future updates will move C470-C479 from CNS to other sites module. |

20230036 | Reportability/Histology--Vulva: Is angiomyxoma (8841/1), such as aggressive angiomyxoma of vulva diagnosed in 2022, reportable? |
Do not report superficial angiomyxoma (8841/0) or aggressive angiomyxoma (8841/0). WHO Classification of Female Genital Tumors, 5th edition, defines deep (aggressive) angiomyoma as a benign, infiltrative, myxoid spindle cell neoplasm that occurs in deep soft tissue of the pelviperineal region. |

20230064 | Primary Site--Cervix Uteri: When no other information is available regarding the origin of the tumor, can an overlapping cervical adenocarcinoma (C538, 8140/3) be coded to the endocervix (C530) based on the histology? See Discussion. |
Adenocarcinoma is a glandular tumor and the endocervix is generally the origin of glandular tissue for the cervix. However, if the only available information is pathology proving a single tumor overlapping the endocervix and exocervix, can we code the site to C530 instead of C538? Applying the current primary site coding instructions, primary site would be coded as C538 because there is no specific statement of the tumor origin; the primary site coding instructions state the tumor is coded to an overlapping site in the absence of a specific statement of origin and there is no existing SINQ confirming the site can be assumed to be the endocervix based on the histology. |
Code Primary Site as Overlapping lesion of cervix uteri (C538). The 2023 SEER Program Coding and Staging Manual Primary Site Coding Instructions for Solid Tumors #4 says to code the last digit of the primary site code to ‘8’ when a single tumor overlaps an adjacent subsite(s) of an organ and the point of origin cannot be determined. This is also supported by the ICD-O-3, 3rd edition, note in the Topography section that states: In categories C00 to C809, neoplasms should be assigned to the subcategory that includes the point of origin of the tumor. A tumor that overlaps the boundaries of two or more subcategories and whose point of origin cannot be determined should be classified to subcategory ‘8.” |

20230067 | First Course Treatment/Scope of Regional Lymph Node Surgery--Breast: How is Scope of Regional Lymph Node Surgery coded when initially there is a sentinel lymph node biopsy (SLNBx) and an intramammary node removed followed a month later by an axillary dissection for a right breast primary? See Discussion. |
Patient has a diagnosis of invasive carcinoma of the right breast from a core biopsy on 04/2023. Subsequent bilateral mastectomy and sentinel node biopsy proves one positive sentinel node and one negative intramammary node. One month later there is a completion axillary node dissection with 15 nodes negative for malignancy. Per previous SINQ 20190074, the initial mastectomy and sentinel node excision with intramammary node removal should be coded as Scope of Regional Lymph Node Surgery 6. It is unclear how the resulting axillary dissection should be recorded in Scope of Regional Lymph Node Surgery. There is no code for sentinel node biopsy and 3, 4, or 5 at same time (code 6) PLUS an additional subsequent axillary dissection. Please provide coding instructions for Sentinel Lymph Nodes Positive, Sentinel Lymph Nodes Examined, and Scope of Regional Lymph Node Surgery in this scenario. |
Scope of Regional Lymph Node Surgery: Assign code 7, Sentinel node biopsy and code 3, 4, or 5 at different times. In this case, the SLNBx (code 2) preceded the regional node dissection (code 5: 4 or more regional lymph nodes removed), i.e., procedures performed in separate surgical events. Sentinel Lymph Nodes Examined: Assign code 98, Sentinel lymph nodes were biopsied, but the number is unknown. In this case, only the results were provided. Sentinel Lymph Nodes Positive: Assign code 01, Sentinel nodes are positive (code exact number of nodes positive). In this case, there was one positive sentinel node. |

20230015 | Solid Tumor Rules/Multiple Primaries: Should two 2021 diagnoses be abstracted as two primaries? The patient has a history of thyroid cancer in 2008 with no evidence of recurrence/progression. In 2021, two abstracts were submitted with a diagnosis of C809, poorly differentiated malignant neoplasm and a C421, myeloproliferative disorder. See Discussion. |
2021-Right pleural fluid: Negative for carcinoma. 5/18/2021: Right iliac crest bone marrow core biopsy, aspirate smear, clot section and peripheral blood smear: Hypercellular bone marrow, morphological findings are suspicious for a myeloproliferative neoplasm. Flow Cytometry: Slight immunophenotypic abnormalities of the myeloid cells. No abnormal B cell, T cell, or NK cell populations identified. Normal female karyotype. KARYOTYPE: 46,XX[20]. Negative for deletion of 13q14.3 (D13S319) by FISH. Negative for deletion of 13q34 (LAMP1) by FISH. Negative for hyperdiploidy involving chromosome 9 by FISH. Negative for t(9;22)(q34;q11.2) by FISH. Negative for deletion of the EGR1 gene on 5q31 by FISH. Negative for monosomy 5 by FISH. Negative for deletion of 7q31 by FISH. Negative for monosomy 7 by FISH. Negative for deletion of 20q12 by FISH. Negative for trisomy of chromosome 8 by FISH. 6/4/21-Left adrenal; biopsy: poorly-differentiated malignant neoplasm with extensive necrosis. Immunohistochemical stains show the neoplastic cells to be negative for CK7, TTF-1 and p63. Negative CK7 and TTF-1 would argue against a lung primary. Correlation with clinical and radiological findings is advised. We are unable to contact the provider. |
Based on the diagnosis date for the unknown primary, use the 2007 MPH Other sites rules. Since the site codes differ for each primary, rule M11 applies, abstract two primaries. |
