Immediate Surgery or Surgery After Sunitinib Malate in Treating Patients With Metastatic Kidney Cancer

RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving sunitinib malate before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving sunitinib malate after surgery may kill any tumor cells that remain after surgery. It is not yet known whether undergoing immediate surgery or surgery after sunitinib malate is more effective in treating patients with metastatic kidney cancer. PURPOSE: This randomized phase III trial is studying immediate surgery to see how well it works compared with surgery after sunitinib malate in treating patients with metastatic kidney cancer.
