Abstract

This is, to our knowledge, the first reported case of secondary Plasma Cell Leukemia that was successfully by pomalidomide plus fixed low-dose dexamethasone. Pomalidomide at a dosage of 4 mg orally on days 1-21 of repeated 28-day cycles associated with fixed low-dose dexamethasone (40 mg on days 1, 8, 15 and 22 of each 28-day cycle), outside of the clinical trials, was started as a final attempt. After the fourth course, the patient achieved an interesting response that included a significant reduction of circulating plasma cells from the peripheral blood, a very important decrease of the M-component, and normalization of haematological value. The toxicities were acceptable. The time to best response was 4 months.
