RATIONALE: Lenalidomide and dexamethasone may stop the growth of multiple myeloma by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well lenalidomide works with or without dexamethasone in treating patients with newly diagnosed multiple myeloma.

Study summary:

OBJECTIVES: Primary - To assess the progression-free survival at 1 year in patients with newly diagnosed symptomatic multiple myeloma treated with lenalidomide alone or in combination with dexamethasone added for disease progression or lack or partial response. Secondary - To assess the response rate of this regimen in these patients. - To assess the toxicity of this regimen in these patients. Tertiary - To examine the effect of lenalidomide alone on tumor specific immunity and global parameters of immune function. - To examine the effect of dexamethasone addition in patients requiring steroids. - To correlate changes in parameters of immune response and measures of disease response. - To examine the antiangiogenic activity of lenalidomide alone and in combination with dexamethasone. - To examine the effect of lenalidomide alone on tumor cell survival and proliferation. OUTLINE: Patients receive oral lenalidomide once daily on days 1-21. Treatment repeats every 28 days for up to 18 courses in the absence of second disease progression or unacceptable toxicity. Beginning in course 4, patients experiencing stable or progressive disease also receive concurrent oral dexamethasone once daily on days 1, 8, 15, and 22 and for all subsequent courses. Blood and bone marrow samples are collected periodically for pharmacological and correlative studies. Samples are analyzed for parameters of immune activation, cell proliferation and apoptosis, and circulating tumor cells and endothelial cells via flow cytometry; global impact of therapy on immune cell subsets via immunophenotype analysis; and angiogenesis via CD34 staining. After completion of study therapy, patients are followed periodically for up to 2 years.
