Understanding the Role of Large Extracellular Vesicles in Lymphomas and Lymphoproliferative Disorders: the "Off the Beaten Track" Liquid Biopsy

It is a 3-year monocentric in vitro study on human tissue. 50 patients with aggressive and indolent Non-Hodgkin Lymphomas (Diffuse Large B-Cell Lymphoma (DLBCL; Group A; n=10), Follicular Lymphoma (FL; Group B; n=10), Marginal Zone Lymphoma (MZL; Group C; n=10), Peripheral T-Cell Lymphoma (PTCL; Group D; n=10), Mycosis Fungoides (MF; Group E; n=10)), and patients with Chronic Lymphocytic Leukaemia (CLL; N=10; Group F; n=10), Hairy Cell Leukemia (HCL; Group G; n=10), and Multiple Myeloma (MM; N=10; Group H; n=10) will be enrolled over a period of 24 months. Follow-up: 12 months. Patients will be enrolled at the Complex Operative Unit of Haematology-IRCCS Azienda Ospedaliero-Universitaria di Bologna. The peripheral blood samples of patients (40 ml) will be collected only at diagnosis within normal clinical practice, outside of clinical study protocols, and following the treatment guidelines in use at the Centre. The analysis of the samples will be performed at the Unità Operativa Complessa di Ematologia-IRCCS Azienda Ospedaliero-Universitaria di Bologna in collaboration with the Istituto Romagnolo per lo Studio dei Tumori 'Dino Amadori' - IRST IRCCS and with the University of Perugia.
