Chimeric Antigen Receptor T-Cell-Associated Cholangiopathy: First Reported Case of a Complication of Chimeric Antigen Receptor T-Cell Therapy.

Chimeric antigen receptor T-cell (CAR-T) therapy is a novel immunotherapy for the treatment of refractory malignancies. While various complications have been described previously, sclerosing cholangitis has not been reported. We report the first description of sclerosing cholangitis secondary to Tecartus CAR-T therapy in a 67-year-old man with refractory stage IV mantle cell lymphoma. As CAR-T therapy becomes increasingly used in clinical practice, it is critical to recognize potential hepatobiliary complications. Further research is needed to facilitate early diagnosis and to develop effective treatment strategies for managing these rare but severe complications.
