title: Enteropathy-associated T-cell lymphoma: epidemiology, clinical features, and current treatment strategies.
abstract: Enteropathy-associated T-cell lymphoma (EATL) is a rare non-Hodgkin lymphoma of T-cell origin. The recent 2008 World Health Organization classification of hematologic malignancies distinguishes between two types of EATL. The disease is associated with celiac disease, particularly with its late, adult onset. Currently, there are no standardized diagnostic or treatment protocols for EATL, mostly because of its rarity. Historically, the patients have been treated with anthracycline-based chemotherapy with or without surgery. The outcome of patients with EATL treated with these approaches is poor. The reported death rates in the biggest studies are approximately 80-84%, with median progression-free survival (PFS) of 3.4-6.0 months and overall survival of 7.1-10.0 months. The 5-year PFS ranged from 3.2% to 18% and OS from 19.7% to 20%. The results of a novel induction regimen with ifosfamide, etoposide, and epirubicin alternating with intermediate-dose methotrexate followed by autologous stem cell transplantation (ASCT) are more promising, with a 5-year PFS of 52% and OS of 60%. The alternative approach, with a more common induction with cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone followed by ASCT has also delivered promising results, with a 3-year PFS of 52% and OS of 47%. This review summarizes recently published data on epidemiology and clinical features, as well as standard and novel treatments including high-dose chemotherapy with ASCT and their outcome in EATL.
