Evaluating Photopheresis Regimens for Advanced CTCL: The Role of the SARS-CoV-2 Pandemic—A Single-Center Retrospective Study

Abstract

Extracorporeal photopheresis (ECP) is an established, safe, and effective treatment for cutaneous T-cell lymphoma (CTCL). There is no published literature reviewing the clinical efficacy of ECP at varying frequencies or the ideal duration of therapy. The SARS-CoV-2 pandemic necessitated a reduced frequency of ECP for patients with CTCL at our center. We performed a retrospective chart review of patients with CTCL receiving ECP at the Penn Dermatology Photopheresis Service (PDPS) on March 1, 2020, and followed up their course until January 31, 2021. Our retrospective cohort study suggests that one day of ECP with extending duration between treatments can be considered an alternative maintenance regimen in appropriate patients with stable disease on concomitant multimodality immunomodulatory therapy.
