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.

Condition Intervention
Multiple Myeloma and Plasma Cell Neoplasm
Genetic: gene expression analysis
Genetic: reverse transcriptase-polymerase chain reaction
Other: immunoenzyme technique

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Proportion of patients with failed disease based on expectations for changes in cathepsin G (CG) levels

Secondary Outcome Measures:
  • Mechanism of development of thalidomide/lenalidomide-induced venous thromboembolism (VTE)
  • Intensity, dynamics, and specificity of CG upregulation in response to thalidomide and lenalidomide treatment
  • Specificity and threshold levels of CG for induction of platelet aggregation in response to thalidomide and lenalidomide and the resulting risk for VTE development

Study Start Date: August 2008
Estimated Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Detailed Description:



  • To analyze the mechanism of development of thalidomide/lenalidomide-induced venous thromboembolism (VTE) in patients with multiple myeloma treated on clinical trial ECOG-E4A03 or E-E1A00.
  • To determine the intensity, dynamics, and specificity of cathepsin G (CG) upregulation in response to thalidomide and lenalidomide treatment.
  • To determine the specificity and threshold levels of CG for induction of platelet aggregation in response to thalidomide and lenalidomide and the resulting risk for VTE development.

OUTLINE: Blood samples obtained before, during, and after treatment with thalidomide or lenalidomide from patients previously enrolled on clinical trial ECOG-E4A03 or E-E1A00 are analyzed to determine the total content of cathepsin G (CG) via ELISA; to determine mRNA levels of CG via RT-PCR; and for platelet aggregation studies. Blood samples are collected from healthy volunteers for platelet preparation.
