Studying Blood Samples From Patients With Multiple Myeloma Who Were Treated With Thalidomide or Lenalidomide
Screening of Cathepsin G Levels in Multiple Myeloma Patients Receiving Treatment With Thalidomide/Lenalidomide Within the ECOG Trials E1A00 and E4A03

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.

OBJECTIVES:

Primary

  • 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.
