Abstract

Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a rare, aggressive subtype of primary gastrointestinal T-cell lymphoma. Owing to the absence of symptoms characteristic of MEITL, diagnosis can be challenging, and the low response rate to conventional chemotherapy leads to an abysmal prognosis. This study aimed to define the clinicopathologic characteristics of MEITL in Korea, evaluate the clinical outcomes of intensive chemotherapy with and without hematopoietic stem cell transplantation (HSCT), and explore prognostic factors.
