About
RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor.
PURPOSE: This phase III trial is studying everolimus to see how well it works in treating patients with kidney cancer who have undergone surgery.
Full description
OBJECTIVES:
Primary
Secondary
OUTLINE: This is a multicenter study.
Patients are stratified according to pathologic stage (intermediate high-risk vs very high-risk), histologic subtype (clear cell vs non-clear cell), and performance status (0 vs 1). Patients are randomized to 1 of 2 treatment arms.
Archived tumor tissue, plasma, and whole blood samples may be collected periodically for biomarker analysis and other translational studies.
After completion of study treatment, patients are followed up every 6 months for 2 years and then annually for 8 years.
