CD4+ T-Cell Lymphoma Harboring a Chimeric Antigen Receptor Integration in TP53

N Engl J Med. 2025 Feb 6;392(6):577-583. doi: 10.1056/NEJMoa2411507.

Abstract

Malignant T-cell transformation after chimeric antigen receptor (CAR) T-cell therapy has been described, but the contribution of CAR integration to oncogenesis is not clear. Here we report a case of a T-cell lymphoma harboring a lentiviral integration in a known tumor suppressor, TP53, which developed in a patient with multiple myeloma after B-cell maturation antigen (BCMA) CAR T-cell therapy.
