ASSURE: Adjuvant Sorafenib or Sunitinib for Unfavorable Renal Carcinoma

Trial Conditions
  • Kidney Cancer
  • Clear Cell Renal Cell Carcinoma
  • Papillary Renal Cell Carcinoma
  • Stage I Renal Cell Cancer
  • Stage II Renal Cell Cancer
  • Stage III Renal Cell Cancer
  • Stage IV Renal Cell Cancer
What is the purpose of this trial?

RATIONALE: Sunitinib and sorafenib 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 or sorafenib after surgery may kill any tumor cells that remain after surgery. It is not yet known whether sunitinib is more effective than sorafenib or placebo in treating kidney cancer. PURPOSE: This randomized phase III trial is studying sunitinib to see how well it works compared to sorafenib or placebo in treating patients with kidney cancer that has been removed by surgery.
