die. Combining more than one drug may kill more cancer cells.\n\nPURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients with acute myeloid leukemia or myelodysplastic syndrome in first relapse or who did not achieve first remission.', 'detailedDescription': 'OBJECTIVES: I. Determine the toxicity, remission rate, event-free survival, and overall survival following induction with cytarabine/mitoxantrone (ARA-C/DHAD), intensification with ARA-C and etoposide (VP-16), and consolidation with cladribine (2-CdA) and VP-16 in patients with acute myeloid leukemia (AML) that is secondary, in first relapse, or has failed initial remission induction therapy. II. Compare the remission induction rate and event-free survival on this trial with prior second-line studies (i.e., protocols CCG-243, CCG-201, and CCG-261P). III. Compare survival of patients on this trial with the survival of patients relapsing or failing to achieve an initial complete remission (CR) on previous front-line AML trials (i.e., protocols CCG-251, CCG-213, CCG-2861, and CCG-2891). IV. Determine the frequency and prognostic significance of mdr1 gene expression and p53, topoisomerase II, and deoxycytidine kinase gene mutations in these patients. V. Determine the disease-free and overall survival of patients achieving a CR on this study in relation to the post-intensification therapy received (i.e., bone marrow transplantation, chemotherapy, or no further therapy). VI. Determine the frequency and degree of abnormal cardiac function on echocardiogram or MUGA at 1 and 5 years in patients treated with mitoxantrone following anthracycline therapy during initial treatment. VII. Provide a control arm evaluating the safety of using phase I or II agents in an "upfront window" approach planned for future CCG studies. VIII. Determine the toxicity, remission rate, event-free survival, and overall survival in patients who fail to achieve a CR with ARA-C/DHAD induction and are then treated with 2-CdA/VP-16. IX. Determine the biologic characteristics, toxicity, remission rate, event-free survival, and overall survival following this treatment regimen in patients who develop AML as a second malignancy.\n\nOUTLINE: Patients who do not achieve M1/M2a marrow following Induction proceed to Salvage Induction; all others proceed to Intensification.

HD ARA-C/VP-16; followed, in patients with persistent CNS disease, CNS relapse, or chloromas, by irradiation using megavoltage equipment (minimum Co60 and maximum 6 MV x-rays or electrons).

TBI (equipment unspecified) with electron boosts to the testes, chest, extramedullary sites, and, if indicated, craniospinal region; VP-16; followed by allogeneic or autologous bone marrow or PBSC.
