Étude III sur le lymphome et la leucémie à cellules B matures

6 novembre 2026 mis à jour par: St. Jude Children's Research Hospital

This is a phase III clinical trial using risk-adapted therapy. Treatment outcomes for children with B-cell NHL are excellent. Further improvements in outcome will likely be achieved through more focused study of the biology of the tumors and prospective studies of the late effects of treatment. Toward this end, this study features a spectrum of prospective biologic and late effect studies performed in patients treated with a modified regimen derived from the very successful LMB-96 regimen.

Description détaillée

  1. This study will perform analysis of newly diagnosed mature B-cell lymphomas (e.g. Burkitt lymphoma/leukemia, DLBCL, and MLBCL) obtained from participants in different parts of the world.
  2. This study will describe the types and frequency of mutations in the ARF-HDM2-TP53 pathway, in B-cell lymphomas in the United States and that found in selected geographic regions of the world.
  3. This study will describe the expression of ARF-HDM2-TP53 and PUMA-associated pathways in B-cell lymphomas in the United States and that found in B-cell lymphomas of other selected geographic regions of the world.
  4. This study will describe the pattern and frequency of XLP gene mutations presenting with B-cell lymphomas in the United States and selected geographic regions.
  5. This study will describe the frequency of EBV-positive B-cell lymphomas in the United States and selected geographic regions of the world: and will describe the pattern of EBV protein and gene expression (e.g., EBNA 3) in EBV-positive lymphomas and the study will compare patterns of EBV protein and gene expression with clinical, laboratory and outcome data.

Exploratory Aims:

To estimate the complete response rate, event-free survival, and overall survival rates in patients with Burkitt lymphoma (BL), Burkitt leukemia/B-cell acute leukemia (B-ALL) and diffuse large B-cell lymphoma (DLBCL) treated with a stage-adapted regimen based on the St. Jude B-cell II protocol.
