Sixty patients with advanced multiple myeloma received 2-6 monthly treatment courses combining hyperfractionated cyclophosphamide (300 mg/m2 i.v. over 3 h q 12 h x 6, d 1-3) with pulsed dexamethasone (20 mg/m2/d p.o., d 1-4, 9-12, 17-20) and once daily thalidomide at individually escalating doses (100-400 mg/d) depending on tolerability (HyperCDT). Responding patients were maintained on daily thalidomide and monthly dexamethasone pulses. Complete, partial and minor response rates were 4%, 68% and 12% respectively; overall response rate was 84% (efficacy analysis). Median event-free and overall survival was 11 and 19 months respectively. During at least one treatment cycle, 67% of patients experienced grade 4 neutropenia resulting in 17% grade 3 and 9% grade 4 infections. Side-effects, presumably related to thalidomide, included neuropathy (40% grade 2, 16% grade 3), constipation (17%), oedema (5%), bradycardia (5%), skin reactions (3%), cerebrovascular events (5%) and deep vein thromboses (8%). Thromboses were not related to known thrombophilic risk factors. Four patients with prior myeloma therapy>50 months developed myelodysplastic syndrome or secondary acute myeloid leukaemia 2-4 months after study entry. HyperCDT is a highly active and reasonably well-tolerated salvage regimen in advanced or refractory multiple myeloma.
