Phase II trial of subcutaneous interferon followed by intravenous hybrid bolus/continuous infusion interleukin-2 in the treatment of renal cell carcinoma: final results of Cancer Biotherapy Research Group 95-09.

Objective: We conducted a phase II trial in metastatic renal cell cancer of outpatient subcutaneous (s.c.) interferon-alpha2b (IFN), followed by an inpatient hybrid schedule of bolus and continuous interleukin-2 (IL- 2).

Phase II trial of subcutaneous interleukin-2, subcutaneous interferon-alpha, 5-fluorouracil and cis-retinoic acid in the treatment of renal cell carcinoma: final results of cancer biotherapy research group 94-10.

Background: The treatment of metastatic renal cell cancer remains unsatisfactory despite encouraging results with biotherapy. Pilot studies from other investigators have suggested that combining cis-retinoic acid and 5-fluorouracil (5FU) with interleukin-2 (IL-2) and interferon-alpha (IFN) may improve outcomes for such patients.

Methods: Eligible patients had metastatic renal cell cancer, were in good medical condition, and had not been treated previously with more than two of the study agents.
