Active clinical trials for "Neoplasms, Plasma Cell"

RATIONALE: Gathering information about how often osteonecrosis of the jaw occurs in patients receiving zoledronic acid for bone metastases may help doctors learn more about the disease and provide the best follow-up care. PURPOSE: This clinical trial is studying osteonecrosis of the jaw in patients with cancer who are receiving zoledronic acid for bone metastases.

RATIONALE: Collecting and storing samples of blood, urine, and tissue from patients undergoing a donor stem cell transplant to test in the laboratory may help the study of graft-versus-host disease in the future. PURPOSE: This research study is collecting and storing tissue and DNA samples from patients undergoing a donor stem cell transplant.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at blood samples from patients with multiple myeloma who were treated with thalidomide or lenalidomide.

This non-interventional retrospective chart review study aims to evaluate the clinical outcomes of patients with RRMM receiving lenalidomide/dexamethasone (Len/Dex) treatment at 1st relapse and the treatment patterns following progressive disease as part of the routine clinical practice in Greece.

The investigators wish to determine which anatomic regions need to be explored in order to correctly diagnose myeloma: whether axial skeletal MRI alone is sufficient or whether it is necessary to perform a total skeletal MRI.

This research study is explore the impact over time of multiple myeloma and its associated treatments on the physical and cognitive function and quality of life of patients and their care partners and how these impacts affect the overall illness experience.

The purpose of this study is to collect a blood or bone marrow sample from patients with multiple myeloma and from volunteers without myeloma.

The purpose of this study is to describe DNA copy number variations and gene expression profiles of bone marrow plasma cells of monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM). The final objective is to search for correlations with the risk of progression in order to establish a predictive model of early malignant transformation.

Background: - Multiple myeloma is a type of cancer that affects white blood cells and has a poor long-term survival rate. Two other types of cancer, monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma (SMM), may eventually progress and develop into multiple myeloma. Researchers are interested in collecting samples from individuals who have been diagnosed with MGUS and SMM to study possible risk factors for developing multiple myeloma. Objectives: - To study risk factors that may cause MGUS and SMM to progress to multiple myeloma. Eligibility: - Individuals at least 18 years of age who have been diagnosed with either MGUS or SMM but do not have multiple myeloma. Design: Participants will be examined by study researchers at the initial visit, at 6 months following enrollment, and every 12 months for a maximum of 5 years. The following tests may be performed: (1) blood and urine tests, (2) bone marrow aspiration and biopsy, (3) imaging studies, and (4) a skeletal survey (a series of skeletal X-rays of the skull, spine, pelvis, ribs, shoulders, upper arm, and thigh bones). Treatment will not be provided as part of this protocol. - Participants will remain on the study for 5 years, or until their MGUS or SMM progresses to multiple myeloma requiring treatment.

The purpose of this study is to see if MRI techniques can be used for early evaluation of cardiac amyloidosis which is sometimes seen in individuals with multiple myeloma. Cardiac amyloidosis is a medical disorder that decreases heart function.
