Two cycles of escalated BEACOPP followed by four cycles of ABVD utilizing early-interim PET/CT scan is an effective regimen for advanced high-risk Hodgkin's lymphoma

Patients and methods: Forty-five newly diagnosed patients with advanced-stage HL and International Prognostic Score >= 3 received two initial cycles of escBEACOPP and then were evaluated by positron emission tomography (PET)/computed tomography scan. If a good imaging response was obtained, they were treated by four cycles of ABVD. Results: Following the first two cycles of escBEACOPP, the overall response was 100% and at the end of all therapy, 40 (89%) patients were in complete response (disappearance of all clinical evidence of disease and PET negativity), three (7%) in partial response (PET-positive residual lesions and a size reduction of the majority of large masses by > 50%), while two (4%) had progressive disease. After a median follow-up of 48 months, progression-free survival (PFS) and overall survival at 4 years were 78% and 95%, respectively. The 4-year PFS for early PET-negative patients (n = 31) and early PET-positive patients (n = 13) were 87% and 53%, respectively (P = 0.01). Conclusions: These data indicate that combined escBEACOPP-ABVD may improve the outcome in patients with high-risk advanced HL. The potential benefit of early-interim PET activity as a guide to continuing therapy in these patients merits further study in the future.
