Abstract:
The role of interferon alpha as maintenance therapy in follicular lymphoma (FL) remains unsolved. We started a controlled clinical trial to assess if interferon alpha 2b could improve outcome, measured with event free survival (EFS) and overall survival (OS) in patients with FL in complete remission after chemotherapy based anthracyclines and adjuvant radiotherapy to sites of initial bulky disease. Three hundred and eighty four patients in complete response after 6 cycles of CEOP-Bleo (cyclophosphamide, epirubicin, vincristine, prednisone and bleomycin, at standard doses), and adjuvant radiotherapy when necessary, were randomized to received Interferon alpha 2b, three times a week for 1 year or no treatment (control group). Median follow up was 9.8 years (range 7.0-15 years); actuarial curves showed that EFS was 64% (95% confidence interval (CI) 56-71%) in patients treated with interferon that was statistically significant to patients in the control group: 35% (95% CI: 28-43%) (p<.01). OS was also statistically significant: 81% in patients treated with interferon (95% CI: 74-93%) and 57% (95% CI: 50-63%) in the control group (p<.001). Toxicity was mild, all patients received the planned dose of interferon on time. The use of aggressive chemotherapy and maintenance therapy with interferon alpha 2b in follicular lymphoma improved outcome; more than 60% of patients remain alive free of disease at longer follow-up.
