Outcomes of Extracorporeal Photopheresis Better in Early Stage GVHD

A study of extracorporeal photopheresis (ECP) in 71 patients has shown that the procedure is effective in treating steroid-refractory or -dependent acute GVHD (aGVHD) or chronic GVHD (cGVHD) with lower severity in the early stages. The aGVHD overall response rate (ORR) and complete aGVHD-free survival for ECP was 65% and 50% respectively. Grade II and III aGVHD ORR response rate was 81% and 67% respectively, with no response seen in patients with grade IV aGVHD. The ORR for ECP in cGVHD was 81% while the complete cGVHD-free survival was 50%. The study also showed that the total nucleated cells and lymphocytes collected during the first eight ECP procedures had no effect on treatment response rates for aGVHD and cGVHD.
