SINQ 20031110 addresses an overlapping lip lesion between skin and the vermillion border. We were instructed to go with area of greatest involvement. Case would be reportable if >50% of tumor was on the vermillion border and site would be coded to vermillion border (C00._). Often times percentage of involvement is not stated and all that is known is that the lesion overlaps skin and mucosa.

There appears to be discrepant information in the 2024 (and prior) SEER manual regarding race coding when the patient is described only as Hispanic/Latina. Page 78 tells us to Code as 01 (White) when: b. There is a statement that the patient is Hispanic or Latino(a) and no further information is available

1. A person of Spanish origin may be any race; however, for coding race when there is no further information other than “Hispanic” or “Latino(a),” assign race as White as a last resort instead of coding unknown.

However, in Appendix D, under "Other Race descriptions", there is a statement that "If no further information is available, code as 99 Unknown." The list includes "Hispanic."

For example, a chest computed tomography showed multiple subsolid and ground glass pulmonary nodules measuring up to 6 mm; findings favored to reflect adenocarcinoma spectrum lesions.  A literature search seems to indicate that adenocarcinoma spectrum lesions include atypical adenomatous hyperplasia through invasive adenocarcinomas.

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?

Please comment on these specific scenarios.

1. A prostate biopsy is suspicious for adenocarcinoma, but the urologist is not considering this malignant, nor is the urologist treating for malignancy, but there is no clear statement from the physician that this is not reportable.  Should this case be abstracted?
2. A prostate biopsy is suspicious for adenocarcinoma, and there is a statement by the physician that this is not yet malignant. Should this case be abstracted?
3. Prostate MRI with PIRADS 4 or 5; however, the treating urologist does not call this malignant and is not treating patient for prostate cancer.  [Example: 2024 Prostate MRI - PI-RADS 4. Follow up with Urologist states patient to repeat Prostate MRI in 1 year and continue with yearly PSA levels and there is no mention of prostate cancer other than the PI-RADS score]. Should this case be abstracted?

The patient had a 2023 endometrial polypectomy and curettage with final diagnosis of “at least serous intraepithelial neoplasia arising in association with an endometrial polyp.” Diagnosis comment states, “There are multiple tissue fragments with highly atypical glandular lining consistent with a high-grade serous neoplasm. There are focal areas which are suspicious, but not conclusive, for stromal invasion.” Subsequent hysterectomy and BSO showed no residual carcinoma.

According to previous SINQ 20210043, serous tubal intraepithelial neoplasm (STIN) is reportable when stated to be high grade. Does the same logic apply to a similar neoplasm in the endometrium and/or endometrial polyp?

Patient was diagnosed on imaging with enhancement along the right optic nerve intraorbital segment, displacing the optic nerve, most consistent with optic nerve sheath meningioma.

Extracranial meningiomas are rare, however SINQ 20230052 does contain an exception for reportability in a different head and neck site because it is not an intracranial location.

It is unclear if this portion of the meninges surrounding the intraorbital optic nerve is still “intracranial” and thus reportable.

The Solid Tumor Rules state that for cases diagnosed in 2022 and forward, p16 testing CAN be used to assign histology code 8085 (squamous cell carcinoma, HPV positive). The rules also state that for cases diagnosed prior to 1/1/2022, code 8085 MUST be based on ISH testing and not p16. ISH testing is not specifically addressed for 2022+ cases, but are we correct in assuming it can still be used as the basis for 8085?

Multiple CAnswer Forum posts and the AJCC 8th edition Head and Neck staging webinar indicate that the correct chapter/registry staging schema in this situation is determined ONLY by p16 results - not ISH testing, and therefore the Schema Discriminator 2 SSDI should be coded as 1 – p16 negative, regardless of ISH results.

While we understand that histology codes should not be changed based on staging criteria, there is a SEER/NAACCR edit, “Schema Discriminator 2, Head and Neck, Histology (NAACCR)” tag number N6802, that will not allow coding 8085 if Schema Discriminator 2 is coded as 1 (p16 negative). The edit does seem to be correctly enforcing the AJCC guidelines for choosing the staging schema, based on the sources noted above. Do the Solid Tumor or Site-Specific Data Items (SSDI) guidelines need to be modified for this situation?

10/25/2023:  Patient presents to dermatology office with a questionable drug eruption having 3 weeks of papular eruptions of Trunk (Left Chest). Punch biopsies were taken that came back as immature hemopoietic infiltrate with monocytic differentiation. Comment: Myelodysplastic syndrome and leukemia cutis are possibilities. Addendum Report: Additional stains were prepared. ERG is strongly positive. CD1a and S100 do not stain the atypical cells.The controls stain appropriately. CD123 perform with appropriate control is also negative. The pattern is that of so-called "leukemia cutis" which could be seen in the clinical setting of myelodysplasia, chronic myelomonocytic leukemia (CMML) or precursor to acute myelomonocytic leukemia (AMML). Recommend work up. The only available information at present is a diagnosis of leukemia cutis, and that there was no prior history of a hematological malignancy in this patient.

SEER Program Coding and Staging Manual indicates high grade dysplasia of esophagus, stomach, and small intestine are reportable. The ICD-O-3.2 does not include “high grade dysplasia” as equivalent to “high grade squamous dysplasia.”

If reportable, would high grade dysplasia (NOS) that originates in the stomach and small intestine default to 8148/2, while esophageal high grade dysplasia (NOS) default to 8077/2?
