Background:
Patients with advanced multiple myeloma (stage III or progressive myeloma) received the CAD protocol every three weeks: cyclophosphamide 200 mg/m2 i.v./orally days 1-4, adriamycin 30 mg/m2 i.v. on day 1 and dexamethasone 40 mg p.o. days 1-4.
Patients And Methods:
Forty-six patients with a median age of sixty years (range 34-84 years) were enrolled. According to Durie-Salmon 44 patients were in stage III, 2 in stage II; 6 patients had renal insufficiency (stage B). Twenty-three patients were pre-treated at least with melphalane/prednisone.
Results:
Remission rates were as follows: complete remission 4%, partial remission 70%, minimal change 11%, no change 11%, progressive disease 4%. After an observation time of 14 months the median progression free interval for 33 patients not treated with subsequent high-dose chemotherapy with stem-cell support was more than 14 months. Overall, treatment was well tolerated. After 209 cycles given febrile neutropenia occurred in 11% of cycles including one fatal outcome. Neutropenia or thrombocytopenia grade 3-4 WHO was recorded in 18% and 6% of the cycles, respectively.
Conclusions:
This study shows that CAD is an effective regimen with an overall remission rate of 74%. The CAD protocol should be further evaluated in prospective trials.
