 Rationale: Interferon has long been used as a therapy for renal cell carcinoma. However, optimal dosing schedules have not been identified and patients have been relegated to receiving the highest possible doses for prolonged periods of time. This high-dose approach often leads to serious adverse effects from toxicity that limits the usefulness and patient tolerance of this treatment. No formal study has determined the relationship if any between the maximal tolerated dose MTD and the biological effective dose of interferon alpha-2b. The current study seeks to fill that gap by gathering research information about different doses of interferon alpha-2b and correlating with measurements of JAKSTAT in the blood. Validation of correlative studies to determine optimum biologic dosing are needed so that therapy may be adjusted appropriately rather then the current approach of maximizing dose. In addition, a trial of low dose daily administered interferon-2b has not been carried out in the current era with refined histologic classification and modern CT imaging scanning. As this therapy potentially has wide applicability, definite response rates need to be documented.
