This study is testing whether stratification of the patients according to biological risk factors for different treatment groups will improve the outcome of patients with clinically high diffuse large B-cell lymphoma (DLBCL).


For young clinically high-risk diffuse large B-cell lymphoma (DLBCL) patients the optimal therapy has not been established. Previous Nordic phase II studies, where dose-dense chemoimmunotherapy (R-CHOEP-14) with systemic CNS prophylaxis (HD-Mtx and HD-AraC) was given, demonstrated favorable outcome in comparison to historical controls. However, the patients with biological risk factors, such as translocation of bcl2 and myc oncogenes or and/or high BCL2 and MYC expression or deletion 17p and/or high P53 expression had significantly higher risk of death, as compared to patients without aberrations. The figures provide evidence for an unmet clinical need for the patients with biological risk factors, and underscore the importance of a clinical trial, where both biological and clinical risk factors play a role in the treatment planning.

In this trial treatment intensity varies according to presence or absence of biological risk factors. All patients receive a prephase medication consisting of prednisone and vincristine and two cycles of R-CHOP and high dose (HD) methotrexate. Subsequently, depending on the biological risk factors either four additional cycles of R-CHOEP (standard arm with no risk factors) or four dose adjusted R-EPOCH courses (experimental arm with risk factors) are given, followed by one course of high dose cytarabine (Ara-C) and R. R-CHOEP courses should be given with a two-week and R-EPOCH with a three-week interval.

Exclusion Criteria

Severe cardiac disease: cardiac function grade 3-4, left ventricular ejection fraction <45%
Impaired bone marrow liver, renal or other organ function not caused by lymphoma, which will interfere with the treatment schedule (Hemoglobin < 9 g/dL, ANC < 1.5 109/L, Platelet count < 75 109/L, creatinine clearance < 40 mL/min, ALT/AST > 2.5 x ULN, bilirubin 1.5 x ULN, INR > 1.5)
Men and women of reproductive potential not agreeing to use effective contraception during treatment and for 18 months after completion of treatment (Effective contraception is combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal or transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable or implantable), intrauterine device (IUD), hormone-releasing IUD, bilateral tubal occlusion, vasectomised partner, or sexual abstinence
Patients with other severe medical problems, including active infections, cardiac or pulmonary disease, history of PML and with an expected short survival for non-lymphoma reasons
Known HIV positivity
Active or chronic hepatitis B virus (HBV) infection (defined as positive HBsAg serology), or active hepatitis C virus (HCV) infection (defined by antibody serology testing). HBsAg, HBcAb, and HCVAb must be tested during screening. Patients who have protective titers of HBsAb along negative HBsAg after vaccination or prior but cured hepatitis B are eligible
Vaccination with a live vaccine within one month prior to randomization
Patients with a malignancy that has been treated but not with curative intent, unless the malignancy has been in remission without treatment for 5 years prior to enrollment
Earlier treatment containing anthracyclines
Psychiatric or mental disorder which make the patient unable to give an informed consent and/or adhere to the protocol
CNS disease as diagnosed by MRI or CSF cytology. Positive CSF flow cytometry below diagnostic threshold level by cytology is allowed
Transformed lymphoma
Primary mediastinal B-cell lymphoma
Pleural or peritoneal fluid that cannot be drained safely
Hypersensitivity to the active substance or any of the other ingredients
History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies or known sensitivity or allergy to murine products
Patients participating in other clinical studies, unless followed for survival
Lower urinary tract constriction, which cannot be treated adequately
Degenerative and toxic encephalopathy
Neuromuscular disease
