In addition to the issue mentioned above, there is a SINQ answer that conflicts with the 2018 ICD-O-3 Histology Update table. SINQ 20130134 indicates indolent systemic mastocytosis is reportable for cases diagnosed 2010 and forward. There is no date restriction indicating the SINQ note applies only for cases diagnosed 2010-2017. Since indolent systemic mastocytosis was changed to borderline (9741/1) for diagnosis year 2018+, should the diagnosis year range be updated for this SINQ answer?

Patient has a history of breast cancer and diffuse large B-cell lymphoma (DLBCL), both treated with chemotherapy and radiation.

On 6/26/19, bone marrow biopsy: MDS with excess blasts-2 (18% dysplastic blasts) in a normocellular marrow (overall 40% cellularity) with trilineage dysplasia. Comment: least myelodysplastic syndrome with excess blasts-2. However, an early/evolving AML cannot be completely excluded. The findings likely represent therapy-related myeloid neoplasm.

MD note on 7/15/19: Diagnosis: MDS, high grade borderline AML with complex karyotype secondary disease. Patient has high grade MDS which is bordering on AML transformation with 20% blasts by IHC and areas higher than this. This is likely secondary to the treatment she has received for her other cancers particularly pelvic radiation for her DLBCL. Given her very high IPSS score, it is likely she will eventually develop AML. No treatment given.

On 7/15/19, bone marrow biopsy: Persistent acute leukemia in a marrow with trilineage dyspoiesis and 23% blasts.

We previously downloaded the 8/22/2018 ICD-O-3 histology update tables which included the note, not reportable for 2018, for both of these terms (with an updated histology 8071/2). SINQ 20180020 confirms differentiated penile and vulvar intraepithelial neoplasia are NOT reportable for 2018 (as does 20160069). However, when looking at the 8/22/2018 ICD-O-3 histology update table today, the not reportable for 2018 comment has been removed and it appears these two terms are reportable. Which is correct?

Washington State added to birth certificates, which allows people to have their certificates changed to this non-binary gender designation. Gender X is defined as a gender that is not exclusively male or female, including, but not limited to: intersex, agender, amalgagender, androgynous, bigender, demigender, female-to-male, genderfluid, genderqueer, male-to-female, neutrois, nonbinary, pangender, third sex, transgender, transsexual, Two Spirit, and unspecified.

Appendix E1 of the 2018 SEER manual references a similar diagnosis as being reportable for vulva and vagina only. However, the WHO Classification of Tumors of the Urinary System and Male Genital Organs (4th ed) does include high grade penile intraepithelial neoplasia as a synonym for 8077/2.

There is no statement of mucinous or non-mucinous in this case, only adenocarcinoma in situ and an obsolete term bronchioloalveolar carcinoma (BAC) which used to be code 8250. However 8250 is now lepidic adenocarcinoma, and does not match this diagnosis.

Although the Histology Rules do include a general note indicating that the preferred term for BAC is now mucinous adenocarcinoma 8253, it is not listed as a synonym in Table 3. As a result it is unclear how to apply this statement in accordance with the H rules.

The ICD-O Histology Updates table also includes Bronchiolo-alveolar carcinoma, non-mucinous which seems to suggest that in order to apply histology code 8252 (non-mucinous) or 8253 (mucinous) one must also have a statement of mucinous or non-mucinous.

The patient was diagnosed in 2018 with met melanoma to the brain found via imaging. The staging procedure was a single axillary lymph node excision which was positive for metastatic melanoma. The exact site of the primary was never determined and the site code is C449. Is the axillary lymph node regional or distant? This affects how I code regional lymph nodes positive, regional lymph nodes examined, and scope of regional lymph node surgery or surgical procedure other site. Similar question was asked in the past (question # 20091101) but I have not found this question restated since the 2018 changes and just want to verify this is still what we are to do.

SINQ 20180050 and 20130041 appear to have conflicting answers regarding the reportability of MBL with CLL (immuno)phenotype.

While the question content of SINQ 20180050 does not reference the CLL phenotype, it is included in the Discussion as part of the oncologist's assessment. The answer does not address the clinical diagnosis of MBL with CLL-phenotype and simply states that monoclonal B-cell lymphocytosis is not reportable.

SINQ 20130041 does include the CLL phenotype information in the primary question and it is expanded on in the discussion as present in peripheral blood. Based on that information, the answer is that it should be reportable and coded as CLL (9823/3).
