Drug-induced kinetic perturbations of the marrow blasts in acute leukemia. Effects of the daunorubicin, cytosine arabinoside and 6-thioguanine combination. 1979

S Amadori, and M C Petti, and C Mastrovincenzo, and M G Testa

Cell kinetic changes induced in the marrow blasts by treatment with a triple cytotoxic regimen including daunorubicin, cytosine arabinoside and 6-thioguanine (DAT) were investigated in 6 previously untreated acute nonlymphocytic leukemia patients. A decrease in the labeling and mitotic indices was consistently observed 24 h after administration of daunorubicin, suggesting a G2 block and a preferential lytic effect on the S-phase cells operated by the drug. Conversely, cytosine arabinoside and 6-thioguanine in combination induced a series of kinetic perturbations variable from case to case; however, three principal patterns of kinetic response were recogized and discussed in detail. Useful information for the planning of a more rational antileukemic therapy can be drawn from a systematic study of the kinetic effects induced by drug combinations.

D008940 Mitotic Index An expression of the number of mitoses found in a stated number of cells. Index, Mitotic,Indices, Mitotic,Mitotic Indices
D001853 Bone Marrow The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D003561 Cytarabine A pyrimidine nucleoside analog that is used mainly in the treatment of leukemia, especially acute non-lymphoblastic leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle. It also has antiviral and immunosuppressant properties.
