title: Prediction of chemotherapy response in human leukemia using in vitro chemosensitivity test.
abstract: We performed the dye exclusion assay (DEA) and the MTT dye reduction assay to determine the drug sensitivity of acute leukemia using short-term microplate cultures. The in vitro results were compared with the clinical response of 31 patients with acute leukemia treated by combination chemotherapy. The true-positive rates of the DEA and MTT assays were 86.7 and 91.3%, respectively; the true-negative rates were 33.3 and 77.8%, respectively; and the predictive accuracy was 62.5 and 87.5%, respectively. The DEA and MTT assays gave comparable results in drug sensitivity testing of leukemic blast cells. Our data suggest that MTT assay is the more suitable for assessing chemosensitivity in acute leukemia.
