Yan Leyfman: Not all “Double-hit” Lymphomas Behave the Same

Yan Leyfman, Medical Oncologist, Co-Founder and Executive Director of MedNews Week, shared a post on LinkedIn:

“Not all “double-hit” lymphomas behave the same.

A new study from MSKCC highlights important biological and clinical differences among high-grade B-cell lymphomas (HGBCL) with MYC rearrangements.

Analyzing 124 patients with advanced-stage HGBCL, investigators found:

  • Complete response rate: 44%
  • 2-year overall survival: 59.8%
  • CNS relapse: 10.1%

Patients treated with dose-adjusted R-EPOCH had better overall survival than those receiving R-CHOP–based regimens.

One of the most notable findings was that MYC/BCL6-rearranged lymphoma demonstrated a particularly aggressive clinical course, with higher rates of CNS relapse and rapid progression after relapse compared with MYC/BCL2-rearranged disease. Molecular profiling also suggested distinct biology, supporting recent classification changes that recognize MYC/BCL6 disease as a separate entity.

Interestingly, contrary to prior observations in DLBCL, patients whose HGBCL transformed from an indolent lymphoma had better survival in this cohort.

These findings reinforce that HGBCL is not a single disease. Understanding the molecular subtype may improve risk stratification, guide frontline treatment decisions, and help identify patients who may benefit from CNS-directed strategies and novel therapies.”
