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."

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.

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.

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?

Note 1 states that this histology is treatment-related neuroendocrine prostatic carcinoma demonstrating complete neuroendocrine differentiation or partial neuroendocrine differentiation with adenocarcinoma after androgen-deprivation therapy (ADT). Conversely, Note 2 says to code 8574/3 only when there is no history of previous prostate adenocarcinoma or history of androgen-deprivation therapy.

The WHO Blue Book does confirm this is a treatment-related histology, so it seems we would only use this for an adenocarcinoma with neuroendocrine differentiation (or even possibly a mixed histology tumor with adenocarcinoma and small cell carcinoma components) if the patient had previous treatment.

If this histology is treatment-related, why would we use this code for a patient without a history of prostate adenocarcinoma or androgen-deprivation therapy? Should Note 2 be corrected?

Does this histology apply to a post-treatment diagnosis of mixed adenocarcinoma and small cell carcinoma? If yes, should this clarification be added?

Patient was diagnosed March 2024 with high grade dysplasia of the gallbladder during excision for clinical history of acute cholecystitis and obstruction.

Per the STR, Table 10 for Gallbladder and Extrahepatic Bile Duct Histologies shows Biliary intraepithelial neoplasia, high grade as code 8148/2. High grade glandular intraepithelial neoplasia of the biliary tract is also code 8148/2.

Recent SINQ 20240021 (GI specific) indicates high grade dysplasia is reportable as high grade glandular intraepithelial neoplasia (8148/2) for stomach, small intestine, and esophagus. Does the same hold true for gallbladder?  If so, then it appears there is a conflict between STR and Appendix E2.

However, using the logic of SINQ 20240021 for this site would appear to contradict Appendix E2 which indicates high grade dysplasia in sites other than stomach, intestine, and esophageal sites is not reportable.

If we can code high grade dysplasia of GI sites to 8148/2, should we accession high grade dysplasia of the gallbladder and other biliary sites in a similar manner? If so, then Appendix E needs to be modified.

We included this histology in SEER Workshop Case 12 and the histology coding accuracy was less than 40%. From emails we received, it is clear that registrars are unaware that the "somatic type malignancy" can vary but code 9084 applies when the diagnosis is teratoma WITH any non-germ cell tumor component. It may be helpful to add a definition for "teratoma with somatic-type malignancy" (9084) to the Solid Tumor Manual.
