Additional fields were designated to capture other types of immunotherapies such as adoptive cell therapy (tumor-infiltrating lymphocytes (TIL) therapy, engineered TCR therapy, chimeric antigen receptor (CAR) T cell therapy, natural killer (NK) cell therapy), and checkpoint blockade therapy (e.g., anti-PD-1, anti-CTLA-4 therapy). This evidence concerns the gene CTLA4 and neoplasm.
