IL-2 in combination with IFN- alpha and 5-FU versus tamoxifen in metastatic renal cell carcinoma: long-term results of a controlled randomized clinical trial.
We conducted a prospectively randomized clinical trial to compare the efficacy and safety of subcutaneous interferon-alpha2a, subcutaneous interleukin-2 and intravenous 5-fluorouracil as home therapy against oral tamoxifen in 78 patients with progressive metastatic renal cell carcinoma. Treatment courses consisted of interferon-alpha2a 5 x 10(6) IU m(-2), day 1 weeks 1 + 4; days 1, 3, 5 weeks 2 + 3; 10 x 10(6) IU m(-2), days 1, 3, 5 weeks 5-8; interleukin-2 10 x 10(6) IU m(-2), twice daily days 3-5 weeks 1 + 4; 5 x 10(6) IU m(-2), days 1, 3, 5 weeks 2 + 3; and 5-fluorouracil 1000 mg m(-2), day 1 weeks 5-8. The tamoxifen group received tamoxifen 80 mg twice daily over 8 weeks. Among 41 patients treated with interleukin-2, interferon-alpha2a and 5-fluorouracil there were 7 complete (17.1%) and 9 partial responders (21.9%), with an overall objective response rate of 39.1% (95% CI, 24.2-55.5). An additional 15 patients (36.6%) were stable throughout therapy. The overall survival was 24 months (range 5-76+). In 37 patients receiving tamoxifen no objective remissions occurred. 13 patients (35.1%) had stable disease and 24 patients (64.9%) showed continued disease progression. The overall survival was 13 months (range 3-73+). In summary, this home-based therapy regimen of interferon-alpha2a, interleukin-2 and 5-fluorouracil demonstrated significant therapeutic efficacy in patients with progressive renal cell carcinoma when compared to hormonal therapy.
