On November 29, 2022, the GvHD Hub held a virtual symposium on the role of extracorporeal photopheresis (ECP) in the management of graft-versus-host disease (GvHD).

Here, we share the presentation given by Professor Hildegard Greinix, Medical University of Graz, Graz, AT, which considered ECP and how it works.

In this presentation, Professor Greinix details the process of ECP (Figure 1), as well as its direct and indirect effects at a cellular level, and discusses the use of ECP, alone or in combination, for both chronic and acute GvHD, and its impact on quality of life (Figure 2), referencing data and outcomes from multiple research studies.

The SF-36 domains of quality of life were scored from 0 to 100.

Watch or download the presentation to learn more about ECP, including:

  • What ECP is and how it works (0:16; slides 56)
  • The Impacts of ECP (3:00; slides 78)
  • ECP in acute GvHD (5:17; slides 1017)
  • ECP in chronic GvHD (15:09; slides 1928)
  • Quality of life during treatment (25:33; slides 2930)
  • Combination treatments with ECP (26:32; slides 3235)
  • Approved and recommended uses for ECP (33:56; slides 3738)

Key points

  • ECP is a process in which blood is externally centrifuged and white blood cells are treated with methoxsalen and ultraviolet A light before being returned to the patient.
  • ECP causes the depletion of alloreactive donor T cells that can cause GvHD.
  • ECP is associated with superior survival compared with anticytokine therapy.
  • Treatment with ECP is well tolerated, with no severe cytopenias recorded.
  • ECP is approved for the treatment of advanced cutaneous T-cell lymphoma.
  • ECP is recommended as a second-line treatment for steroid-refractory acute and chronic GvHD.
