DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed renal cell carcinoma
  • Clear cell or non-clear cell allowed
    • No disease of the collecting duct or medullary carcinoma
  • Considered pathologically either intermediate high-risk or very high-risk disease
  • No history of distant metastases
  • Patients with microvascular invasion of the renal vein of any grade or stage (as long as M0) are eligible
• Have undergone a full surgical resection (radical nephrectomy or partial nephrectomy) including removal of all clinically positive nodes
  • Surgical margins must be negative
    • Patients with positive renal vein margins are eligible unless there is invasion of the renal vein wall at the margin (provided no other margins are positive)
  • Patients must be registered within 84 days after the date of the first surgical resection of the first tumor
• No evidence of residual or metastatic renal cell cancer on CT scan of the chest, abdomen, and pelvis (all with oral and IV contrast) performed after nephrectomy and within 28 days before registration
  • Patients must have a complete physical examination and medical history within 28 days prior to registration
  • MRI scans of the abdomen and pelvis with gadolinium and a non-contrast CT scan of the chest may be substituted if the patient is not able to have CT scans with IV contrast
  • Patients who display subcentimeter pulmonary nodules (by CT scan) that are non-specific and considered unlikely to represent metastatic disease by the treating investigator will be considered eligible

  • Optimal lipid control must be achieved before registration and monitored during protocol treatment
• No uncontrolled diabetes mellitus (defined by fasting serum glucose > 1.5 times ULN) obtained within 28 days prior to registration.
  • Optimal glucose control must be achieved before registration and monitored during protocol treatment
