Update to Current Manual/Race: For the Example #15 under Race Coding Examples in the 2024 SEER manual, could coding these as 97 result in an under-reporting of Native Hawaiians? See Discussion.
First course treatment--Kidney: How should the different treatment fields be coded if surgery is planned but cancelled due to patient noncompliance, then the tumor is treated with ablation, and eventually surgery is given due to residual disease? See Discussion.
Reportability--Brain and CNS: Is an optic nerve meningioma reportable if stated to arise in the “intraorbital segment” of the optic nerve meninges? See Discussion.
EOD 2018/EOD Primary Tumor--Cervix: How is Extent of Disease (EOD) Primary Tumor of the cervix coded when it invades into the bladder on surgery and noted as T4. No further information is provided, and it is not possible to contact the physician for clarification. Would you code 550 (Bladder wall; bladder, NOS excluding mucosa), 750 (Bladder mucosa), or 999 Unknown?
Reportability/Histology--Digestive Sites: Is a diagnosis of “tubulovillous adenoma with high grade dysplasia” in the duodenum equivalent to a diagnosis of “tubulovillous adenoma, high grade” and, therefore, non-reportable, or is this a reportable non-colorectal high grade dysplasia? See Discussion.
First Course Treatment/Neoadjuvant Therapy--Esophagus: Should the Neoadjuvant Therapy data item be coded as 1 or 2 when the patient completes all but one cycle of the planned neoadjuvant therapy and the managing physician notes the patient completed the neoadjuvant therapy? See Discussion.
Reportability/Ambiguous Terminology--Prostate: Should cases be reported and abstracted based on ambiguous terminology, e.g., suspicious for prostate cancer, when the physician is not treating the case as malignant? See Discussion.
Reportability/Histology--Stomach: According to the AJCC manual, histology codes 8240 and 8249 are excluded from site code C160. Does that mean that I cannot use either of these histology codes with C160 even if the pathologist's diagnosis is neuroendocrine carcinoma?
Solid Tumor Rules/Histology--Breast: What is histology code of a breast tumor with ductal carcinoma, lymphoepithelioma-like carcinoma type? See Discussion.
