- Alliance for Clinical Trials in Oncology
- Brief Summary
RATIONALE: Collecting and storing samples of blood from patients with cancer to study in the laboratory may help doctors learn more about cancer and identify biomarkers related to cancer.
PURPOSE: This laboratory study is looking at biomarkers of angiogenesis and disease in patients with unresectable malignant mesothelioma treated on clinical trial CALGB-30107.
- Detailed Description
OBJECTIVES:
* Determine if elevated levels of thrombospondin I serum levels, vascular endothelial growth factor receptor I, fibroblast growth factor, transforming growth factor, and mesothelin portend a poor prognosis in patients with unresectable malignant mesothelioma treated with vatalanib on protocol CALGB-30107.
* Determine if elevated levels of thrombospondin I serum levels, vascular endothelial growth factor receptor I, fibroblast growth factor, transforming growth factor, and mesothelin correlate with response or stable disease in these patients.
OUTLINE: Serum samples previously obtained from patients on protocol CALGB-30107 are tested for levels of thrombospondin I serum, vascular endothelial growth factor receptor I, fibroblast growth factor, transforming growth factor, and mesothelin using enzyme-linked immunosorbent assays (ELISA).
PROJECTED ACCRUAL: A total of 47 specimens will be accrued for this study.
