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 neoadjuvant chemotherapy (Carboplatin and Paclitaxel) concurrent with radiation per the managing physician. The physician stated the patient completed the neoadjuvant therapy; however, it was also noted that patient completed five cycles of chemotherapy, but the sixth cycle was held due to neutropenia.

The SEER Manual does not address how to code Neoadjuvant Therapy when the patient completed almost all the planned neoadjuvant therapy. It seems inappropriate to code Neoadjuvant Therapy as 2 (Started but not completed) simply because the patient did not have one cycle of chemotherapy but is otherwise felt to have completed neoadjuvant therapy per the managing physician. Does the managing physician’s statement of “completion” impact how this scenario is coded?

The 2022 ICD-O-3.2 Implementation Guidelines indicate “Tubulovillous adenoma, high grade” is 8263/2 and is not SEER reportable. However, the 2024 SEER Manual and clarification from recent SINQs (20240021 and 20240025) confirm high grade dysplasia in the esophagus, stomach, and small intestine is reportable (8148/2).

Which reportability reference applies to a diagnosis of a tubulovillous adenoma with high grade dysplasia in non-colorectal sites?

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.

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?

The race category in some hospital electronic medical record systems includes a combined category of “Native Hawaiian/Pacific Islander.” What race code should be used in a situation where the only available information is “Native Hawaiian/Pacific Islander?”

Malignant Central Nervous System (CNS) Rule M5 instructs us to abstract a single primary (as malignant) when a single tumor is originally diagnosed as non-malignant, the “First course treatment was active surveillance (no tumor resection),” and the subsequent resection pathology is malignant.

This patient’s first course of treatment was not active surveillance. While the patient did not have first course tumor resection, the tumor was treated with Cabergoline.

Should Rule M5 apply because there was no tumor resection? If so, should Rule M5 clearly state no tumor resection is the criteria (not active surveillance)?

SINQ 20230023 does indicate a PitNET diagnosis following a diagnosis of pituitary adenoma does not fall into standard rules, but in the previous SINQ the first course treatment was a partial resection.

It is unclear whether other types of treatment could result in a new malignant PitNET, following a previously treated non-malignant pituitary tumor.

In the 2024 Solid Tumor Rules update, the small cell neuroendocrine carcinoma row in Table 2 was changed. The NOS histology became neuroendocrine carcinoma, NOS (8246) and both large cell and small cell neuroendocrine carcinomas (8013 and 8041, respectively) became the subtype/variants. This change impacts Rule H4 but Rule H4 was not updated. Rule H4 still refers to small cell neuroendocrine carcinoma as being the NOS histology.

In the prior STR versions, it was clear the tumor in question would be coded as 8045 per Rule H4 and Table 2. Considering Rule H4 was not updated according to the changes for Table 2, does histology 8045 still apply to this diagnosis?

There is currently no way to arrive at a histology for this case. Does Rule H4, bullet 3 need to be updated to indicate, “subtype/variant of neuroendocrine carcinoma mixed with any other carcinoma (does not apply to sarcoma)”?

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."
