Due to disease heterogeneity and variability in clinical practice, establishing a large-scale Chinese PTCL database to characterize real-world treatment patterns and clinical outcomes is a critical undertaking. A retrospective cohort will define the clinical epidemiology of the disease, while a prospective cohort will delineate current treatment pathways and outcomes in routine practice and explore the molecular features of PTCL in the Chinese population, thereby providing evidence to support precision therapy.
