A link to a list of current clinical trials is included at the end of this section. For some types or stages of cancer, there may not be any trials listed. Check with your doctor for clinical trials that are not listed here but may be right for you.
Resectable Gastrointestinal Stromal Tumors
Resectable gastrointestinal stromal tumors (GISTs) can be completely or almost completely removed by surgery. Treatment may include the following:
Surgery to remove tumors that are 2 centimeters...
Multiple myeloma, other plasma cell dyscrasia, or lymphoma will develop in 12% of patients by 10 years, 25% by 20 years, and 30% by 25 years.
All patients with MGUS should be kept under observation to detect increases in M protein levels and development of a plasma cell dyscrasia. Higher levels of initial M protein levels may correlate with increased risk of progression to multiple myeloma.[1,2] In a large retrospective report, the risk of progression at 20 years was 14% for an initial monoclonal protein level of 0.5 g/dL or less, 25% for a level of 1.5 g/dL, 41% for a level of 2.0 g/dL, 49% for a level of 2.5 g/dL, and 64% for a level of 3.0 g/dL.
Treatment is delayed until the disease progresses to the stage that symptoms or signs appear.
Patients with MGUS or smoldering myeloma do not respond more frequently, achieve longer remissions, or have improved survival if chemotherapy is started early while they are still asymptomatic as opposed to waiting for progression before treatment is initiated.[3,4,5,6] Newer therapies have not been proven to prevent or delay the progression of MGUS to a plasma cell dyscrasia.
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with monoclonal gammopathy of undetermined significance. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
