Brief Summary: RATIONALE Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die Combining more than one drug may kill more cancer cells
PURPOSE Phase I trial to study the effectiveness of topotecan and etoposide in treating patients who have recurrent or refractory leukemia
Detailed Description: OBJECTIVES I Determine the maximum tolerated dose of topotecan when combined with etoposide in patients with relapsed or refractory acute myelogenous leukemia acute lymphoblastic leukemia or blastic phase chronic myelogenous leukemia II Determine the toxicity of this regimen in these patients III Measure serum levels of topotecan at steady state and correlate them with any change in topoisomerase II content in leukemic blasts IV Assess whether it is feasible to correlate any upregulation of topoisomerase II expression with tumor response to etoposide in subsequent Phase II studies V Assess whether levels of pretreatment expression of topoisomerases I and II in leukemic cells are predictive of clinical response VI Assess whether it is feasible to develop a pharmacodynamic assay based on posttreatment apoptotic changes in leukemic blasts and whether this could be correlated with tumor response in subsequent phase II trials VII Determine the response in patients treated with this regimen
