Concurrent severe disease (according to the investigator's decision). Active bacterial, viral or fungal infection. Poor renal function (serum creatinine level > 150 µmol/L) or impaired liver function tests (total bilirubin level > 30 µmol/L, transaminases > 2.5 upper normal limits) unless they are related to the lymphoma. Poor bone marrow reserve as defined by neutrophils < 1.5 x 109/L or platelets < 100 x 109/L, unless related to bone marrow infiltration. Any history of cancer during the last 5 years, with the exception of non basal cell carcinoma of the skin or in situ carcinoma of the cervix. Treatment with any investigational drug within 30 days before planned first cycle of chemotherapy and during the study. Patient under tutelage.
