Current research status of diagnosis, treatment and prognostic factors of T-lymphoblastic lymphoma

T-lymphoblastic lymphoma(T-LBL) is a rare and highly aggressive lymphoma, with poor prognosis. It occurs mostly in children and male adolescents, and its main symptoms are mediastinal mass, lymphadenectasis, bone marrow invasion and central nervous system(CNS) invasion, etc.. The diagnosis of T-LBL is mainly based on lymph node biopsy, bone marrow cell morphology, immunology, cytogenetics and gene detection. After definitive diagnosis of T-LBL, the patients should be treated with extensive combined chemotherapy and sequential hematopoietic stem cell transplantation (HSCT) or maintenance treatment. There are many factors influencing the prognosis of T-LBL patients, such as age, bone marrow invasion, CNS invasion, disease stage and gene mutations. This article intends to introduce the development of diagnosis, therapy and prognostic factors of T-LBL to provide reference for the diagnosis and therapy of T-LBL.
