OBJECTIVES:
* Maintain and expand tissue repositories of myeloma specimens from uniformly treated Southwest Oncology Group (SWOG) patients with multiple myeloma, smoldering myeloma, Waldenstrom's macroglobulinemia, amyloidosis, or monoclonal gammopathy of undetermined significance.
* Utilize scientific information generated from intergroup and collaborative studies to assist the SWOG Myeloma Committee in the development of new and more effective treatment regimens for these patients.
OUTLINE: Patients receive treatment as directed by the treatment protocols on which they are registered. Specimens of blood and/or marrow are submitted to the Myeloma Repository. The status of the patient (e.g., pre-study, post-remission, or relapse) will be recorded prior to specimen collection.
