Inclusion Criteria

For first randomization:
- Patients with a confirmed histologic diagnosis of diffuse large B-cell lymphoma (DLBCL) based upon a representative histology specimen according to the WHO classification (see appendix A)
- DLBCL must be CD20 positive
- Ann Arbor stages II-IV (see appendix C)
- Age 18-65 years and age-adjusted IPI 1-3 OR age 66-80 years and age-adjusted IPI 0-3
- WHO performance status 0 – 2 (see appendix E)
- Written informed consent

For second randomization:
Patients achieving a CR (or FDG-PET negative PR/CRu) after 6 (elderly) or 8 (young patients) cycles of R-CHOP14 will be randomized to maintenance treatment with rituximab or no further treatment.
- Patients in complete remission or FDG-PET negative partial remission/unconfirmed complete remission at least 4 weeks after the last cycle of R-CHOP14 (including last rituximab administration)
- Time interval since last cycle of R-CHOP14 (including last rituximab administration) between 4 and 8 weeks
- No rituximab-related adverse event necessitating stopping of rituximab administration
- No active infection
- Written informed consent

- Serious underlying medical conditions, which could impair the ability of the patient to participate in the trial (e.g. ongoing infection, uncontrolled diabetes mellitus, gastric ulcers, active autoimmune disease)
- Life expectancy < 6 months
- Prior treatment with chemotherapy, radiotherapy or immunotherapy for this lymphoma, except a short course of prednisone (< 1 week) and/or cyclophosphamide (< 1 week and not in excess of 900 mg/m2 cumulative) or local radiotherapy in order to control life threatening tumor related symptoms
- History of active cancer during the past 5 years, except basal carcinoma of the skin or stage 0 cervical carcinoma
