About

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.

PURPOSE: This phase II trial is studying how well giving sunitinib malate before and after surgery works in treating patients with metastatic kidney cancer.

Full description

OBJECTIVES:

Primary

• Determine if neoadjuvant sunitinib malate can achieve a clinical benefit of 70% or more to the primary renal tumor prior to surgery and adjuvant sunitinib malate in patients with metastatic renal cancer.

Secondary

• Determine the time to radiological progression in these patients.
• Determine the overall survival of these patients.
• Determine the proportion of patients suitable for nephrectomy after neoadjuvant sunitinib malate.
• Determine the translational endpoints.

OUTLINE: Patients receive oral sunitinib malate once daily on days 1-28. Treatment repeats every 6 weeks for 3 courses. Approximately 2 weeks later, patients undergo a standard radical nephrectomy with lymph node dissection. Beginning at least 2 weeks after surgery, patients receive oral sunitinib malate on days 1-28. Courses repeat every 6 weeks in the absence of disease progression or unacceptable toxicity.

Blood and tissue samples may be collected periodically for laboratory studies.

After completion of study treatment, patients are followed every 2 months.

Inclusion and exclusion criteria

DISEASE CHARACTERISTICS:

• Histologically confirmed renal cell carcinoma

  • Measurable metastatic disease on CT/MRI imaging
  • Patients with suspicion of renal cancer on radiology must have a biopsy to confirm diagnosis of clear cell disease

• No prior therapy for renal cancer

• Judged by the treating physician to have the potential to derive clinical benefit from this treatment

PATIENT CHARACTERISTICS:

• ECOG performance status 0-2
• Absolute neutrophil count ≥ 1 x 10^9/L (without growth factor support)
• Platelet count ≥ 75 x 10^9/L
• Total bilirubin ≤ 2 times upper limit of normal (ULN) (except for patients with Gilbert disease)
• Serum creatinine ≤ 2 times ULN
• Serum transaminases < 5 times ULN
• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception during and for ≥ 28 days after completion of study therapy
• Willing and able to comply with scheduled visits, treatment plan, and laboratory tests and other study procedures
• No congestive heart failure, myocardial infarction, or coronary artery bypass graft within the past 6 months, or ongoing severe or unstable arrhythmia requiring medication
• No other severe acute or chronic medical or psychiatric condition, or abnormal laboratory results that would impart, in the judgement of the investigator, excess risk associated with study participation or study drug administration or would make the patient inappropriate for entry into this study
