Introduction: In a prior study, we demonstrated that ACVBP + consolidation was superior to 3 cycles of CHOP + radiotherapy in young patients (pts) with localized aggressive lymphoma (Reyes F et al. N Engl J Med 2005;352:1197). This randomized trial compared in these pts ACVBP vs. ACVBP + a short course of rituximab (R-ACVBP).Methods: untreated pts between 18 and 65y with stage I/II DLBCL and no adverse prognostic factors according to the aa-IPI were eligible. ACVBP consisted of 3 induction cycles given every 2 weeks: doxorubicin (75 mg/m2) day 1, cyclophosphamide (1.2g/m2) day 1, vindesine (2 mg/m2) day 1 and 5, bleomycin (10 mg) day 1 and 5, prednisone (60 mg/m2) day 1 to 5 followed by consolidation with metothrexate, ifosfamide, VP-16 and cytarabine. R-ACVBP consisted of the same regimen combined with 4 doses of rituximab (375 mg/m2) on day 1, 15, 29 and 43. Primary objective was EFS.Results: From 01/04 to 03/08, 223 pts were randomized, 113 in ACVBP and 110 in R-ACVBP arm. Characteristics were: median age 49y (18-65), stage I 63%, extranodal involvement 45%, bulky disease 4%. CR was 94% in ACVBP and 97% in ACVBP arm (ns). With a median follow-up of 43 months, the 3-y EFS was 82% (95% CI, 73% to 88%) in ACVBP and 93% (95% CI, 87% to 97%) in R-ACVBP group (P=0.0487). The 3-y PFS was 83% (95% CI, 74% to 89%) and 95% (95% CI, 89% to 98%) respectively (P=0.0205). OS did not significantly differ with a 3-y estimates of 97% (95% CI, 90% to 99%) for ACVBP and 98% (95% CI, 92% to 100%) for R-ACVBP (P=0.686). In multivariate analysis, a longer PFS was associated with R-ACVBP arm (P=0.0302) and lower b2-m level (P=0.0164). The same proportion of pts (27%) experienced at least 1 SAE in both groups. There were 4 deaths in each arm, with 1 treatment-related death in R-ACVBP (pneumocystis jiroveci pneumonia).Conclusion: the addition of only 4 doses of rituximab to ACVBP significantly improves EFS and PFS in younger pts with low-risk localized DLBCL.
