What was measured

Estimated 3-year EFS where EFS is calculated as the time from study enrollment to disease progression, disease relapse, occurrence of a second malignant neoplasm, death from any cause or last follow-up whichever occurs first. Kaplan-Meier method is used for estimation. Patients without an event are censored at last contact.

Analysis population: Only eligible patients are considered in the analysis of this outcome measure

Groups in this outcome

Arm I (Low-dose Lenalidomide)

Patients receive low-dose lenalidomide PO QD on days 1-21. Treatment repeats every 28 days for up to 26 courses in the absence of disease progression or unacceptable toxicity. Lenalidomide: Given PO Pharmacological Study: Correlative studies

Arm II (High-dose Lenalidomide)

Patients receive high-dose lenalidomide PO QD on days 1-21. Treatment repeats every 28 days for up to 26 courses in the absence of disease progression or unacceptable toxicity. Lenalidomide: Given PO Pharmacological Study: Correlative studies
