A 5-year retrospective analysis of alpha-interferon usage.
Alpha interferon is an immune modulator used in the treatment of hematologic malignancies and immunosuppressive diseases. While many of the clinical indications for interferon have been well described and are FDA-approved, a large number of clinical uses of interferon are being developed. This study evaluated the appropriateness, efficacy, and safety of interferon therapy at our institution from 1987 to 1991. Data were collected by chart review. Response rates of patients in this hospital were compared to those published in the literature. Twenty-six patients were prescribed alpha interferon. Ten patients (38%) demonstrated a partial response, the highest responses seen in Hairy cell leukemia (67%) and chronic myelogenous leukemia (57%). Response rates for each disease compared favorably to those predicted from the literature. Twelve patients (46%) demonstrated intolerance. Overall five patients (19%) remain on therapy. While interferon appears to be moderately effective in certain diseases, intolerance to interferon seems to be the major limiting factor to its clinical application.
