Newly Diagnosed Myeloma Patients, who achieved efficacy above VGPR after initial treatment were enrolled. Patients were then randomly assigned to Id and Rd groups for maintenance treatment. Therapeutic effectiveness will be reviewed monthly until intolerant side effect or disease progression appear . The follow-up period is approximately 2 years. Progression-free survival (PFS)was defined as the duration from randomization to the first evidence of disease progression or death from any cause. Overall survival (OS) was defined as the duration from the randomization to death from any cause. The Kaplan-Meier method was employed to plot the survival curves, with the log-rank test to assess the differences.

Patients were then randomly assigned to Id and Rd groups for maintenance treatment. Therapeutic effectiveness will be reviewed monthly until intolerant side effect or disease progression appear .
