Role of interferon alfa-2b in the induction and maintenance treatment of low-grade non-Hodgkin's lymphoma: Results from a prospective, multicenter trial with double randomization (original) (raw)

Journal of Clinical Oncology

Abstract

To evaluate the effectiveness of adding interferon (IFN) alfa-2b to chemotherapy in the induction treatment of low-grade non-Hodgkin's lymphoma (NHL), and to assess the role of maintenance IFN. A multicenter, two-phase controlled trial with double randomization was conducted in 155 patients with low-grade NHL. In the first randomization, 78 patients received cyclophosphamide, vincristine, and prednisone (CVP) and IFN, 3 MU/m2 three times a week for 3 months, and 77 patients received CVP alone. Responding patients were randomized to receive IFN for 1 year versus observation. Of 144 assessable patients, 73 received CVP + IFN and 71 received CVP. Responses were similar: CVP + IFN 79% versus CVP 76% (P = .62). The number of patients who did not complete the treatment was higher in the CVP + IFN group than in the CVP group (18% v 4%; P = .009), although the received dose-intensity of chemotherapy was comparable. Duration of response and progression-free survival (PFS) were significan...
