Thalidomide, Doxorubicin, and Dexamethasone in Treating Patients With Untreated Stage II or Stage III Multiple Myeloma

OBJECTIVES: I. Determine the response rate of patients with previously untreated stage II or III multiple myeloma treated with thalidomide, doxorubicin, and dexamethasone. II. Determine the safety and toxicity of this regimen in this patient population.

OUTLINE: Patients receive oral dexamethasone on days 1-4, 9-12, and 17-20, doxorubicin IV on day 1, and oral thalidomide daily. Treatment repeats every 30 days for 4 courses in the absence of unacceptable toxicity or disease progression.

PROJECTED ACCRUAL: A total of 21-45 patients will be accrued for this study within approximately 1 year.
