Example: FoundationAct assay of circulating tumor DNA in blood sample results: Tumor type = non-small cell lung carcinoma, NOS, with 3 genomic alterations identified: NRAS Q61H, IDH2 R140Q and TP53 V172F. The tumor was identified on imaging and the imaging findings were not clearly what one would expect to see with a SCLC.

IMC-A12 (Cixutumumab) is listed as a BRM agent in SEER*Rx, but the Remarks section indicates it should be coded as Other Therapy until there is FDA approval. It is unclear if FDA approval was ever given for this agent. We are mainly seeing it given for prostate primaries.

Example: Bone marrow biopsy diagnosis is chronic myelogenous leukemia, chronic phase, and the RT-PCR test result proved, BCR-ABL1 p210 (Major Breakpoint) - Detected, 3.3659%.

Even though the p210 fusion transcript was less than 5%, it was detected. The presence of BCR-ABL1 does define whether or not patients are treated with tyrosine kinase therapies. Therefore, it seems likely that the presence of any BCR-ABL1 would be captured using the more specific histology code 9875/3, instead of the non-specific CML, NOS histology code 9863/3.

Are there minimum threshold requirements for these quantitative studies in order to code the histology to the more specific type of CML?

According to the AJCC CAnswer Forum (https://cancerbulletin.facs.org/forums/node/160948), celiac axis nodes are considered regional for the liver. However, for liver primaries, Extent of Disease (EOD) regional lymph nodes list the following as regional lymph nodes:

• Caval
• Hepatic, NOS
  • Hepatic artery
  • Hepatic pedicle
  • Inferior vena cava
  • Porta hepatis (portal) (hilar) [in hilus of liver]
• Periportal
• Portal vein
• Regional lymph node(s), NOS

Based on this information, should celiac axis lymph nodes be considered as regional for liver primaries when coding EOD Regional Nodes?

The pathology report states "Right mediastinal mass: poorly differentiated non-small cell carcinoma with neuroendocrine differentiation." This is the only histologic confirmation of this lung primary that is collected.

1. Path report for breast cancer has final diagnosis as 'DCIS' but the CAP protocol in the body of the report says 'microinvasion seen, T1mic.'

2. Path report says 'DCIS' in the final diagnosis and microinvasion is identified in the microscopic portion of the report, but it is not in CAP protocol format and not stated in the final diagnosis.

According to the literature, CIC gene rearrangement sarcomas in young patients are soft tissue sarcomas with an aggressive clinical course and may have previously been grouped under the Ewing-like family of tumors or as undifferentiated round cell sarcomas. There is currently no guideline in the solid tumor rules for coding a CIC gene rearrangement sarcoma. However, coding the histology to 8800 (sarcoma, NOS) seems unlikely to capture the more aggressive nature of these tumors. Can a more specific histology be coded?

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.
