Abstract

Multiple myeloma (MM) remains an incurable disease, but response rates to new drugs are promising, offering the majority of patients a significant prolongation of overall survival. The objective of this study was to evaluate time to progression (TTP), event-free survival (EFS), and overall survival (OS) in MM patients treated with a combination of cyclophosphamide (CY), thalidomide (THAL) and dexamethasone (DEX). This study included 132 untreated and relapsing/resistant patients treated with the low-thalidomide dose CTD regimen. The patients received CY 500 mg/m(2)i.v. or 625 mg/m(2) orally at day 1, THAL 100mg/day á la longue and DEX 20mg/day at days 1-4 and 8-11, every 28 days. Patients received 6-9 cycles; ORR by 3 months was 59.1%, by 6 months 65.6% and by 9 months 75.6%. In patients responding to CTD therapy (CR, nCR, PR), the probability of survival for 20 months was 89.3%. The outpatient low-thalidomide dose CTD regimen is well tolerated and produces a significant response rate both in untreated and relapsing/resistant MM patients.
