Brief summary: This is a randomized, open-label, multi-center, phase 3 study evaluating the efficacy of R-ACVBP and DA-EPOCH-R in patients with newly diagnosed non-germinal b-cell-like diffuse large B-cell lymphoma

Detailed description: Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma. According to Hans' algorithms, DLBCL can be identified as 2 subtypes: germinal b-cell-like(GCB) and non-germinal b-cell-like(non-GCB). Approximately 50 to 60% of diffuse large-B cell lymphoma(DLBCL) was non-GCB subtype DLBCL. Although the introduction of rituximab in immunochemotherapy has dramatically improved the outcome of patients with DLBCL, The survival was still poor in non-GCB DLBCL patients treated with R-CHOP.

The LNH03-2B study has shown that R-ACVBP regimen gave a longer PFS (93% vs. 74% at 3 years, p=0.0074) and a longer OS (97% vs. 83% at 3 years, p=0.0067) than R-CHOP in young patients with non-GCB DLBCL. It also showed that R-ACVBP regimen gave a longer PFS (87% vs. 73% at 3 years, p=0.0074) and a longer OS (92% vs. 84% at 3 years, p=0.0067) than R-CHOP in young low-intermediate risk DLBCL patients. The LNH2003-3 study has shown that in high-risk (2/3 IPI factors) DLBCL patients treated with R-ACVBP followed by auto-ASCT results in a 74% PFS and 76% OS. Hematological toxic effects of the intensive regimen were raised but manageable.

The CALGB study showed that in DLBCL patients at least 18 years of age and at least stage II, DA-EPOCH-R regimen is effective in both GCB and non-GCB subtypes, with a 5-years TTP 67%, EFS 58% and OS 68% in non-GCB subtype DLBCL. It is encouraging that PETHEMA Group study showed that in the long-term follow-up of untreated DLBCL patients with poor prognosis, DA-EPOCH-R achieved a 70.8% EFS and 76.4% OS at 10 years in non-GCB subtype DLBCL.

However the efficacy of R-ACVBP compared to DA-EPOCH-R in patients with newly diagnosed non-germinal b-cell-like diffuse large B-cell lymphoma remains unknown. All the above-mentioned results led us to propose a randomized trial comparing R-ACVBP to DA-EPOCH-R in previously untreated patients with non-GCB DLBCL.

Eligibility criteria: Inclusion Criteria:

* Patient with histologically proven CD20+ diffuse large B cell lymphoma (WHO Classification),
* aaIPI\>1,
