RATIONALE: Interferon alfa may interfere with the growth of tumor cells. Interleukin-2 may stimulate a person's white blood cells to kill tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining interferon alfa and interleukin-2 with fluorouracil may kill any remaining tumor cells following surgery. It is not yet known whether combining interferon alfa and interleukin-2 with fluorouracil is more effective than observation after surgery for kidney cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of combining interleukin-2, interferon alfa, and fluorouracil to that of observation alone in treating patients who have undergone surgery for kidney cancer and are at high risk of relapse.

Condition Intervention Phase

Enrollment: 96
Study Start Date: February 1998
Primary Completion Date: January 2004 (Final data collection date for primary outcome measure)
Detailed Description:


  • Compare the effect of adjuvant combination therapy comprising interleukin-2, interferon alfa, and fluorouracil vs observation only on disease-free survival or overall survival of patients with renal cell carcinoma at high risk of relapse after radical surgery.
  • Compare the quality of life of patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive interleukin-2 subcutaneously (SC) on days 3, 4, and 5 of weeks 1 and 4 and on days 1, 3, and 5 of weeks 2 and 3. Patients also receive interferon alfa SC once weekly during weeks 1 and 4 and 3 times weekly during weeks 2, 3, 5, 6, 7, and 8. Patients then receive fluorouracil IV on day 1 of weeks 5, 6, 7, and 8.
  • Arm II (control arm): Patients receive no adjuvant treatment before disease progression.

Quality of life is assessed at baseline and at 2 and 6 months after randomization.

Patients are followed monthly for 3 months (arm I only), every 3 months for 1 year, every 6 months for 4 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 550 patients (275 per treatment arm) will be accrued for this study within 3 years.
