Lenalidomide treatment for refractory or relapsed multiple myeloma in elderly patients may be feasible in an outpatient setting. However, difficulties have been associated with the management of adverse effects. Therefore, a dose reduction in lenalidomide has been recommended in some cases. In this report, we encountered the successful treatment of myeloma in 6 elderly patients (aged above 70 years) with very low-dose lenalidomide (5 mg daily). Four patients exhibited more than a partial response with an 8.6 months median follow-up period, which was comparable with previous findings. The major adverse effect observed was infection, which occurred during the first several cycles. Others were less toxic, especially the absence of grade 3/4 toxicities for hematological adverse effects.Although a dose reduction in lenalidomide therapy for elderly patients is controversial, a very low dose could be safe and effective. Our group is currently conducting a multi-center prospective trial to evaluate the efficacy of low-dose lenalidomide therapy.
