Perspectives on the Mature T-Cell Lymphomas in the Middle East: A Comprehensive Review of the Present Status

Background: T-cell lymphomas (TCLs) are rare and aggressive malignancies associated with poor outcomes, often because of the development of acquired drug resistance as well as intolerance to the established and often toxic chemotherapy regimens in elderly and frail patients. The many subtypes of TCL are well established to exhibit marked geographic variation. The epidemiology, clinical presentation, diagnosis, prognosis, and treatment of TCLs in the Middle East (ME) are yet to be explored; hence, limited data are available about these entities in this part of the world. Aim: Therefore, in this review article, we aim to discuss the available data regarding the T-cell neoplasms in the ME, including the incidence of specific subtypes of peripheral T-cell lymphoma (PTCL), as well as the trends in survival and treatment, all in an effort to understand the natural history of these complex entities across the ME.
