In the modified CART (KM-CART) procedure, the recovery rates of albumin and globulin in 11 cancer patients were reported to be 71.1% ± 9.6% and 57.6% ± 7.1%, respectively, without membrane cleaning [14], while the protein recovery rate was 40.7% ± 14.0% in 4781 procedures with membrane cleaning [9], which were comparable to the data in this study. Here, ALB is linked to cancer.
