Among 17 patients, depending on the antigen expression of tumor tissue, 12 underwent CD19 CART cells (including 9 with murine-CD19 and 3 with humanized-CD19), with the median number of CART cells infusion of 1.44×106 cells/kg (rang of 0.22×106 cells/kg to 3.8×106 cells/kg); 4 underwent hCD20 CART cells, with a median number of CART cells infusion of 1.29×106 cells/kg (range of 0.94 × 106 to 2.06 × 106); and 1 underwent hCD22 CART cells, with infusion of 5.9×106 cells/kg. The gene discussed is CD19; the disease is neoplasm.
