โฆ Synopsis
Eleven patients with acute leukemia (acute lymphatic leukemia 8, acute myeloid leukemia 3) were treated with cytosine arabinoside and cyclophorphamide; two also received asparaginase and two others prednisone. Nine of them had refractory disease in which reinduction with vincristine and prednisone had failed; two others were unable to tolerate vincristine and so this drug was not used again. In 7 of the 11 patients (acute lymphatic leukemia 5, acute myeloid leukemia 2), a complete remission was readily achieved. We suggest that this combination therapy is effective and should be considered as an alternative to vincristine and prednisone when these drugs are no longer beneficial particularly in acute lymphatic leukemia.

Thirteen leukemic patients with disease refractory to conventional chemotherapy were treated with 1.0 to 7.5 g/m2 of Cytosine Arabinoside (Ara-C) over 29 drug cycles. Drug infusions were spaced at 12-hour intervals; a maximum of four doses was administered over 36 hours. After single dose tolerance
The development of resistance to Ara-C by leukemia cells may be a multifactorial process. These include diminished rates of anabolism or increased rate of catabolism to Ara-C, competition for incorporation into DNA by higher pool size of the competing normal metabolite, dCTP and perhaps other mechan
Forty-four patients with a diagnosis of refractory or relapsed acute myelogenous leukemia received salvage chemotherapy with high-dose cytosine arabinosine 3 g/m2 intravenously over 2 hours every 12 hours for six doses and mitoxantrone 5 mg/m2 intravenously daily for 5 days. Overall 16 patients (36%
