Peripheral T-cell lymphomas–not otherwise specified (PTCL-NOS) is a broad category of biologically and clinically heterogeneous diseases, which likely does not have a single treatment paradigm. Understanding of subtype-specific approaches is leading to more individualized therapy. There are also therapeutic vulnerabilities to target, such as CD30, JAK/STAT pathway, and epigenetic modifiers, that may cross different histologic subtypes. As new therapies evolve, however, it is important to understand in which situations current standard treatments work, because some of these treatments, such as combination chemotherapy, are potentially curative for a subset of patients. For certain populations, adding to these chemotherapy backbones will produce the best results. For other populations, entirely new approaches may be appropriate. Future treatment advances will, in part, be made by enriching populations based on their likelihood of response to specific therapies and utilizing biomarker-driven or biomarker-informed strategies.
