T-Cell Project: Prospective Collection of Data in Patients With Peripheral T-Cell Lymphoma

The designed study follows up the retrospective previous one by the International T-cell Non-Hodgkin's Lymphoma Study Group (International Peripheral T-Cell Lymphoma Project). It is designed as a prospective collection of information potentially useful to predict the prognosis of newly diagnosed patients with the more frequent subtypes of Peripheral T-cell lymphoma (Peripheral T-cell lymphoma unspecified and Angioimmunoblastic T-cell lymphoma) and to better define clinical characteristics and outcome of the more uncommon subtypes
