Solid Tumor Rules/Multiple Primaries--Bladder: How many primaries and what M Rule applies for a diagnosis of noninvasive micropapillary urothelial carcinoma (8131/2) in 2019, followed by a diagnosis of noninvasive papillary urothelial carcinoma (8130/2) in 2024?
Solid Tumor Rules/Histology--Lung: What is the histology code for a lung case with a diagnosis only stated as "high-grade neuroendocrine tumor" in 2022? As the disease was advanced, limited workup was done, and no more specific diagnosis was provided. See Discussion.
Summary Stage 2018--Ovary: What is the summary stage for an ovarian primary in 2024, in which the ovary capsule was ruptured with surgical spill? See Discussion.
Reportability/Histology--Heme & Lymphoid Neoplasms: How should this unusual 2023 pathology-only case be reported and coded for leukemia cutis? See Discussion.
Update to the Current Manual/Tumor Size Summary—Neoadjuvant Treatment: Would you clarify instructions in the 2024 SEER Program Coding and Staging Manual (SPCSM) for Tumor Size Summary when a patient receives neoadjuvant treatment? There seems to be a conflict with the STORE Manual. See Discussion.
EOD 2018/Primary Tumor--Breast: We are having difficulty deciding when we can or cannot use physician-assigned TNM staging to code EOD data items if the medical record or hospital abstract documentation is unclear. As a central registry, we are unable to query physicians for clarification. Please advise what is a “discrepancy” in the EOD General Instructions to “Use the medical record documentation to assign EOD when there is a discrepancy between the T, N, M information and the documentation in the medical record.” See Discussion.
Reportability/Histology--Heme & Lymphoid Neoplasms: Should a non-Langerhans cell histiocytosis involving the hypothalamus and pituitary gland be accessioned as a reportable, behavior /1, CNS neoplasm? See Discussion.
