The aim of the trial is to evaluate the molecular characteristics and MDD/MRD of B-NHL in pediatric patients in order to identify on the one hand the very high risk group and to prescribe them more intensive treatment on the other hand to identify those patients who don't need very aggressive therapy. One more study question is to evaluate the role of PET/CT in assessment of the completeness of remission.
The following primary study questions are going to be analyzed:
Secondary study questions will address
Detailed Description:
Risk group stratification:
R1: resection status: complete, stage I and II R2: resection status: incomplete, stage I and II R3: resection status: incomplete, stage III and LDH < 2 x ULN R4: resection status: incomplete, stage III and LDH ≥ 2 x ULN, stage IV/B-AL and CNS negative; CNS +
For patients with very limited disease (R1- stage I/II СR), the addition of rituximab might allow the omission of anthracyclines and vincristine without jeopardizing survival rates but reducing acute and long term toxicities. In this treatment arm, it is tested whether the event-free survival is similar to that of the historical control For patients with limited disease (R2- stage I/II NR), the addition of rituximab might allow the omission of anthracyclines without jeopardizing survival rates but reducing acute and long term toxicities.
For patients with limited disease (R3 - stage III and LDH < 2 x ULN ), the addition of rituximab might allow reduce the number of blocks to four without jeopardizing survival rates but reducing toxicities For patients with obligate factors of poor prognosis (additional adverse cytogenetic findings (TP-53, 11qLOH) it is tested whether the event-free survival can be improved by adding rituximab and adding blocks R-VICI
