Treatment of acute myeloblastic leukemia in adults: remission induction with a combination of cyclophosphamide, cytarabine and vincristine.

A regimen of intravenous cyclophosphamide, cytarabine and vincristine, given over a four-day period and repeated every two to three weeks, was used to treat 33 patients with acute myeloblastic leukemia. Of the 30 evaluable patients 9/18 previously untreated patients achieved complete remission and two others marked improvement, and 4/12 previously treated patients achieved complete remission. Twelve of 16 patients under the median age of 38 responded while only 3/14 patients over this age responded. There was no difference in response between those with elevated muramidase levels and those with normal levels. Three patients developed a previously unrecognized syndorme of fever, malaise, rash and orbital suffusion. Cytarabine was probably responsible.At least four courses of treatment are required before abandoning this regimen of therapy. Patients who achieve a complete remission and live for more than 150 days spend about 25% of their total survival time from diagnosis in hospital.

Plasma cell myeloma: response of melphalan-resistant patients to high-dose intermittent cyclophosphamide.

High-dose intermittent cyclophosphamide was used in the treatment of 19 patients with plasma cell myeloma who had demonstrated resistance to melphalan. Good objective improvement was found in six patients and partial responses in five. Patients have survived from three to more than 36 months (estimated median 21 months) after starting cyclophosphamide, and 11 are still alive. The important implications of the lack of cross-resistance between these two alkylating agents are discussed in terms of the mechanisms of cellular resistance to alkylating agents.
