Models extracted predefined binary variables (e.g., modified Response Evaluation Criteria in Solid Tumors [mRECIST] tumor response, alpha-fetoprotein [AFP] dynamics, Barcelona Clinic Liver Cancer [BCLC] stage) and ordinal variables (e.g., liver segment involvement, vascular invasion, follow-up assessment) using a standardized system prompt and output template. This evidence concerns the gene AFP and neoplasm.
