Prospective Observational International Registry of Patients With Newly Diagnosed Peripheral T Cell Lymphoma.

This study T-Cell Project 2.0 is based on the former International PTCL study designed by the International T-cell Non-Hodgkin's Lymphoma Study Group (T-Cell Project 1.0: Prospective Collection of Data in Patients With Peripheral T-Cell Lymphoma) as a prospective collection of data to predict the prognosis of patients with the more frequent subtypes of PTCL. It is a prospective, longitudinal, international, observational study of patients with newly diagnosed peripheral T-cell lymphoma aiming to verify whether this prospective collection of data would allow achieving a more accurate information on T-cell lymphomas. The study aims to better define the clinical relevance of the new WHO Classification, the role of FDG-PET in staging and response assessment, the prognosis of different entities, the genomic landscape of different subtypes, and to investigate on most optimal treatment strategies for these neoplasms in the real-world population as well as molecular markers and to explore the prognostic or predictive implications of them in PTCL.
