OUTLINE: Patients are treated with altretamine (HMM) and etoposide for 2 weeks followed by 2 weeks of rest. This cycle is repeated for a minimum of 2 and a maximum of 6 cycles if there is no progression of disease. Patients who are in complete remission receive an additional 2 cycles (total of 8 cycles). There are different cohorts consisting of 4 patients each in which toxic effects will be evaluated with escalating doses of this combination. The MTD is defined as the dose level immediately below that at which half of the patients experience dose-limiting toxicity. Patients are followed for relapse and survival.
