This study began as an efficacy study of interferon alpha-2a in patients with hairy cell leukemia. It was observed that most patients responded with interferon, but that very few complete responses were being obtained. Studies being done elsewhere confirmed the low complete remission rate. Once interferon was stopped, nearly uniform disease progression requiring reinstitution of therapy was observed. There appears to be very few if any patients who will not require further therapy after receiving 12 or 18 months of continuous interferon treatment. Because of these findings, and in order to ...
