Prognosis of high-risk patients with diffuse large B-cell lymphoma is still less then optimal. According to revised Int. Prognostic Index, patients with 3-5 adverse prognostic factors have only about 50% chance of survival in 4 years. In theory, there are 3 possibilities how to improve prognosis of patients with poor-risk DLBCL: intensification of induction therapy, high-dose consolidation treatment with autologous stem cell transplant or combination of both methods.

|---|---|
| Main Objective: To compare PFS in arms treated with intensive immuno-chemotherapy followed by observation or by HDT and ASCT in early PET negative (PET-) pts and To determine safety and PFS of intensified salvage immuno-chemotherapy followed by HDT and ASCT in early PET positive (PET+) pts.;Secondary Objective: To compare EFS and OS in arms treated with intensified immuno-chemotherapy followed by observation or by HDT and ASCT in early PET negative pts To determine ORR, CR, EFS and OS of the intensified salvage immuno-chemotherapy followed by HDT and ASCT in early PET positive pts and compare PFS, EFS and OS with outcomes of the early PET negative patients.;Primary end point(s): PET negative part of the protocol: To compare progression free survival (PFS) between arms treated with rituximab-based immunochemotherapy followed by observation or by HDT + ASCT in early PET negative young (under 60) high intermediate or high risk (aaIPI 2-3) CD20+ DLBCL patients. PET positive part of the protocol: To determine safety and progression free survival (PFS) of rituximab-based salvage immunochemotherapy followed by HDT + ASCT in early PET positive young (under 60) high intermediate or high risk (aaIPI 2-3) CD20+ DLBCL patients. | — |
