title: [Relationship between Ara-C sensitivity of leukemic-colony forming units (L-CFU) and [3H] deoxycytidine suicide test of L-CFU].
abstract: Ara-C sensitivity test and suicide tests of L-CFU using [3H] deoxycytidine (dCyd) and [3H] thymidine (TdR) were performed in patients with acute nonlymphocytic leukemia (ANLL) and with chronic myeloid leukemia in blastic crisis (CML-BC). We found a correlation between ara-C sensitivity and the [3H] dCyd suicide test of L-CFU (p less than 0.001); and between ara-C sensitivity and the [3H] TdR suicide test (p less than 0.05). These results suggest that the [3H] dCyd suicide test reflects the degree of activity of ara-C metabolism in L-CFUs.
