Keep an eye on blood values during CAR-T therapy


Immunotherapy with so-called CAR-T cells has become established for the treatment of various leukaemias (blood cancers) and lymphomas (cancers of the lymph glands). More and more patients are being treated. 7420._300jpgA team led by Dr. Kai Rejeski and Prof. Marion Subklewe from Medical Clinic III of the LMU Hospital has discovered that many patients suffer from a side effect that initially fell under the radar: a sometimes life-threatening, sometimes long-lasting drop in blood cells. Together with international partners, the Munich team has shed light on this phenomenon and developed a score that can be used to stratify high- vs. low-risk patients for this CAR-T cell side effect before starting therapy. This is important because CAR-T therapy is also to be given outside of trials on an outpatient basis in the future. Under these circumstances, it is particularly crucial to know early on who is at risk for prolonged cytopenia - and who is not.
