Summary

This study involves patients with plasma cell dyscrasia including monoclonal gammopathy of undetermined significance (MGUS) or multiple myeloma (MM), with and without sleep apnea, who are providing bone marrow specimens. Specimens will be obtained at the time that patients undergo a standard-of-care procedure in order to minimize discomfort and reduce any risk.

PROCEDURE

Bone Marrow Aspirate and Biopsy

The aspirate sample obtained for research at the time a standard-of-care biopsy is taking place will be approximately 40cc. Bone marrow aspiration removes bone marrow fluid and cells through a needle placed into the bone. Usually this sample is taken from the back of the pelvic bone, but it may also be taken from the sternum or the front of the pelvic bone. A bone marrow biopsy removes bone with the marrow inside and is done prior to the aspirate. Each biopsy and aspirate procedure takes approximately 15 minutes total. Bone marrow aspirate may be collected in a separate tube for research or collected from the standard-of-care specimen with left-over aspirate not otherwise needed for clinical purposes, or from previous procedures.
