Abstract

Cutaneous T-cell lymphomas (CTCLs) are a group of T-cell lymphomas with low incidence. Due to their indolent characteristics, treatment strategies have not yet been established for advanced CTCLs. In this study, relative incidence of CTCLs in Asia was estimated and the therapeutic outcomes presented based on various treatments currently used in clinics for advanced CTCLs. As part of a prospective registry study of peripheral T-cell lymphoma (PTCL) conducted across Asia, including Korea, China, Taiwan, Singapore, Malaysia, and Indonesia, subgroup analysis was performed for patients with CTCLs. Among 486 patients with PTCL, 37 with CTCL (7.6%) were identified between April 2016 and February 2019. Primary cutaneous ALK-negative anaplastic large cell lymphoma (ALCL, 35.1%) was the most common subtype. With a median follow-up period of 32.1 months, median progression-free survival (PFS) was 53.5 months (95% CI 0.0–122.5), and overall survival was not reached. 14 patients (48.2%) underwent subsequent treatment after the first relapse, but the response rate was 20% with a PFS of 2.2 months (95% CI 0.3–4.0). Six patients received autologous stem cell transplantation (auto-SCT). However, auto-SCT did not result in better outcomes. Additional studies are needed on standard care treatment of advanced or refractory and relapsed CTCLs.
