Yanagida E, et al. - Experts attempted to study retinoic acid-related orphan receptor-γt (RORγt) expression in patients with peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). In this analysis, pathological and clinical investigations were performed for 170 cases of PTCL-NOS. According to the findings obtained, RORγt-positive PTCL-NOS showed a tendency for better overall survival. Results of this study suggested that RORγt-positive PTCL-NOS could be a subpopulation of PTCL-NOS.
