Per SEER 20140003, an omentectomy is not recorded under Surgery of Other Site when performed with a hysterectomy for an endometrial primary. Is this still correct? CoC appears to have different guidelines stating in a forum that an omentectomy is coded in data item Surgical Procedure to Other Site. I would like to confirm SEER guidelines. Is this one of those unique situations that SEER and STORE differ? Our state follows SEER guidelines and would like to communicate the appropriate rules to our facilities.

Path report reads: 7/15/2019 A. Endometrium, curettings: Serous carcinoma, high grade. B. Endometrial polyp, curettings: Serous carcinoma, high grade.

If coded to 8461/3, according to AJCC, this would not be an ideal code (since it is outdated). Also, endometrium is not included in the suggested site codes for 8461/3 according to the 8/22/2018 ICD-O-3 update.

Patient had a vulvar biopsy with final diagnosis of Extramammary Paget neoplasm (intraepithelial glandular neoplasm). No invasion identified. We are unable to contact the pathologist or physician for clarification.

Although this terminology is not listed in the ICD-O-3, web search results refer to this as a possible synonym for Paget disease with associated VIN III, which is reportable.

Per the site validation list: https://seer.cancer.gov/icd-o-3/sitetype.icdo3.20190618.pdf#search=site%20validation, ill-defined sites (ILL-DEFINED C760-C768) does not include 8070- Squamous cell carcinoma as a valid histology. Therefore when a Cervical Lymph Node and Unknown Primary Tumor of the Head and Neck is submitted with a C760 and 8070/3, it requires an override be set.

CT a/p read by radiologist shows: "Bosniak 4 cystic lesion of right kidney." Follow-up MRI a month later reads "right kidney cystic lesion with enhancing mural nodule concerning for cystic renal cell carcinoma (RCC)." Urologist consult used the same wording of "Bosniak 4 cystic lesion" and "concerning for renal cell carcinoma." Treatment discussed but due to patient health status recommended repeat imaging. Repeat CT few months later reads: "cystic right renal lesion with enhancing nodule similar to most recent prior and suspicious for cystic RCC."

Though "suspicious for cystic RCC" per latest imaging is reportable, Bosniak 4 is "clearly malignancy, ~100% malignant" by definition, so is the case actually reportable with the first CT a/p date as date of diagnosis?

The bone marrow biopsy proved bone marrow with blasts comprising 15-19%. Neither the pathologist nor the physician specifically diagnosed this as AML, calling this only high risk disease or early evolving AML prior to starting the patient on Vidaza.

No further information can be obtained from the pathologist or the physician for this case. Should this early evolving AML be accessioned as an additional primary per Rule M10, or is this the same MDS that is now high risk as the blast count is up to 19%, but has not yet reached the threshold of 20% blasts usually required for AML per the Hematopoietic and Lymphoid Neoplasm Database?

We received an edit error in SEER*DMS on the following site/histology (Orbit, NOS (C696)/9699/3) that involved an incorrect staging code being assigned to SS2018. The staging language is identical in AJCC, EOD and SS2018. SEER*RSA notes that SS2018 should be coded distant, but in the SS2018 manual, this language is noted Regional. Staging language is: Orbital adnexal lymphoma AND extraorbital lymphoma extending beyond the orbit to adjacent structures--Bone, Brain, Maxillofacial sinuses

10/4/2018 Frozen Section Diagnosis: Brain tissue with atypical cells and inflammatory cells, defer to permanents for further evaluation. Note: Tissue for flow cytometry is submitted. Final Diagnosis: Preliminary Diagnosis: Brain Tumor, Biopsy: Neoplasm, suggestive of lymphoma (see comment). Comment: The tumor exhibits nuclear atypia and increased mitosis. The tumor cells are immunologically positive for LCA and with very high ki67 labeling index. GFAP and synaptophysin are not expressed by tumor cells. The above suggests a lympho-proliferative process. This case is forwarded to the hematopathology service of this department for further evaluation. The final diagnosis report will be issued by the hematopathologist as an addendum.

Supp Rpt Add Addendum Diagnosis: The brain biopsy showed brain tissue large lymphoid cell infiltrate. Additional immunohistochemical stains are performed. The large cells are positive for CD20, BCL2, BCL6 (subset), MUM1, and CD30, negative for CD3, CD5, and CD10. Staining for c-MYC is negative. Ki-67 positive large cells are approximately 18%. EBER is strongly positive by ISH. Diagnosis: Brain lesion, biopsy: EBV+ Diffuse Large B-cell Lymphoma. Addendum Comment: The concurrent flow cytometric study showed monoclonal lambda-positive B-cells without out CD5 and CD10 expression, consistent with B-cell lymphoma.

While we recognize the Heme DB has been the correct source for histology coding for heme and lymphoid neoplasms dating back to 2010, the ICD-O-3.2 Implementation Guidelines appear to provide incorrect coding instructions. Histologies 9670/3, 9728/3, 9729/3 and 9836/3 are listed in Table 3 - Deleted ICD-O codes in ICD-O-3.2.

While we recognize these histologies have been included in this Table because they have now been deleted, it is unclear whether the Comments regarding their use listed in the 4th column of the Table is correct. For each of these histologies, the comment states the histology listed in the 1st column (ICD-O-3/3.1) should be used prior to 2021. For example, for histology 9670/3, the comment states: Cases diagnosed prior to 1/1/2021 use code 9670/3. Cases diagnosed 1/1/2021 forward use code 9823/3. However, each of these histology codes have been obsolete for cases diagnosed 1/1/2010 and later. If registrars were following the Heme DB and Heme Manual instructions (the appropriate coding source for these neoplasms), these histologies would not have been used in a decade.

Should the Comments column in Table 3 be updated? Or should a Note follow the Table indicating registrars should not use these histology codes for cases diagnosed after 1/1/2010, and these histology codes have been deleted for cases diagnosed 1/1/2021? It seems misleading to indicate any of these are valid histology codes for a 2010-2020 diagnosis when the Heme DB confirms these histology codes only apply to cases diagnosed prior to 2010.
