| Secondary Objective: ;Main Objective: The first aim is to test the impact of replacing Prednisolone by Dexamethasone during induction treatment on the improvment of the event free survival of patients newly diagnosed with T- LBL. The second aim is to test whether for patients with T-LBL the standard maintenance therapy of 24 months total terapy duration can safely be reduced to 18 months;Primary end point(s): The conditional event free survival (EFS), defined as minimum time from the date of randomisation to: death by any cause progressive disease non-response at day 33 late event EFS will be estimated using the Kaplan-Meier method Second end poin overall survial:defined as time of death by any cause (from randomisation) acute and long term toxicity non lymphoma related and early deaths | — |
