We are aware that the WHO 4th edition for urinary tumors has changed the behavior of “clear cell papillary renal cell carcinoma” to /1 but registries are to continue collecting as /3.

While the diagnosis in our case is stated as “tumor” it does seem like the pathologist may be using the new WHO terminology of “tumor” rather than “carcinoma,” so we are not sure if behavior is /3 or /1.

Example 4:  Esophageal biopsy with diagnosis of “focal areas suspicious for adenocarcinoma in situ.” Diagnosis on partial esophagectomy specimen “with foci of high grade dysplasia; no invasive carcinoma identified.” Do not accession the case. The esophagectomy proved that the suspicious biopsy result was false.

Appendix E2 #32 of the SEER Manual states high grade dysplasia in site other than stomach, small intestines, and esophageal primary sites are not reportable. Does this mean high grade dysplasia is reportable for esophagus primaries?

Based on the Solid Tumor Rules, we would make this two since it is over one year. According to a previous SINQ question 20110046, we are to code this as one primary. We see patients come back with multiple carcinoid tumors over the years and would like clarification.

Example: 12/2023 Breast lumpectomy final diagnosis is Invasive ductal carcinoma, lymphoepithelioma-like carcinoma type. This is a single tumor with no in situ carcinoma present.

Lymphoepithelioma-like carcinoma is not listed as a subtype/variant or synonym for breast carcinoma in the Solid Tumor Rules histology tables.

Additional comments in this pathology report state "The entire case was sent in consultation to an ophthalmic pathologist. [Pathologist] assigns a conjunctival melanocytic intraepithelial neoplasia (C-MIN) score of 2-3 due to the upward pagetoid migration of small, dendritic melanocytes. A C-MIN score of 2-3 is between low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL; C-MIN 2) and high-grade conjunctival intraepithelial lesion (HG-CMIL; C-MIN 3). The older terminology for this lesion would be primary acquired melanosis (PAM) with mild to focally moderate atypia."

This term does not appear in the SEER Program Coding and Staging Manual (SPCSM), Appendix E1 of the SPCSM, or Solid Tumor Rules (specifically rule H3) . 

In the NAACCR Coding Pitfalls 2023 webinar, the example of DCIS, solid type is given. The webinar advised us to code 8230/2 (ductal carcinoma in situ, solid type). When going through the beginning of the solid tumor rules in the Changes from 2007 MPH Rules section it states "DCIS/Carcinoma NST in situ has a major classification change. Subtypes/variant, architecture, pattern, and features ARE NOT CODED. The majority of in situ tumors will be coded to DCIS 8500/2." In the equivalent or equal terms section it lists "Type, subtype, variant" can be used interchangeably.

Since the example has it listed as as ductal carcinoma in situ, solid "type," would we code 8500/2 or 8230/2? 

Patient was diagnosed in July 2022 with biopsy confirmed left kidney renal cell carcinoma. Initially, partial nephrectomy was planned for February 2023 but canceled at the last moment due to the patient’s “history of narcotic use.” The details of that cancellation were otherwise unclear. It appears the treatment plan was changed due to patient non-compliance.

Patient then had cryoablation of the tumor in May of 2023. Subsequent imaging in October found residual tumor, but no disease progression was noted. Again, additional ablation was offered but patient decided on surgical treatment which did not occur until December 2023.

Is the cryoablation second course due to a change of plan if there is no disease progression, recurrence, or treatment failure?

If the cryoablation is first course treatment, then would the partial resection also be first course treatment because it was documented as the treatment plan?

Example: Patient has a 04/2023 diagnosis of symptomatic anemia not responsive to Retacrit. Further testing includes diagnostic bone marrow biopsy 10/2023 proving MDS with low blasts and SF3B1 mutation, treated with Relozyl (Luspatercept).

There is no SEER*Rx listing for Reblozyl or Luspatercept. Per web search, Luspatercept, sold under the brand name Reblozyl, is a medication used for the treatment of anemia in beta thalassemia and myelodysplastic syndromes.

Is this non-cancer directed treatment since it is given to address the anemia rather than the MDS? If cancer-directed treatment, how should it be coded?
