Abstract

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. Key words: Precursor T-cell lymphoblastic leukemia-lymphoma; Genetics; Immunology; Diagnosis; Therapy

t淋巴母细胞淋巴瘤的诊断、治疗及预后因素的研究现状
T淋巴细胞淋巴瘤(T-LBL)是一种罕见的高度侵袭性淋巴瘤,预后不良。多发于儿童和男性青少年,主要症状为纵隔肿块、淋巴结肿大、骨髓侵犯和中枢神经系统(CNS)侵犯等。T-LBL的诊断主要基于淋巴结活检、骨髓细胞形态学、免疫学、细胞遗传学和基因检测。在明确诊断为T-LBL后,患者应接受广泛的联合化疗和连续造血干细胞移植(HSCT)或维持治疗。影响T-LBL患者预后的因素有很多,如年龄、骨髓侵犯、中枢神经系统侵犯、疾病分期和基因突变。本文旨在介绍T-LBL的诊断、治疗和预后因素的发展,为T-LBL诊断和治疗提供参考。关键词:前体T细胞淋巴细胞白血病淋巴瘤;遗传学;免疫学;诊断;治疗

期刊介绍: The International Journal of Transfusion and Hematology was founded in September 1978. It is a comprehensive academic journal in the field of transfusion and hematology, supervised by the National Health Commission and co-sponsored by the Chinese Medical Association, West China Second Hospital of Sichuan University, and the Institute of Transfusion Medicine of the Chinese Academy of Medical Sciences. The journal is a comprehensive academic journal that combines the basic and clinical aspects of transfusion and hematology and is publicly distributed at home and abroad. The International Journal of Transfusion and Hematology mainly reports on the basic and clinical scientific research results and progress in the field of transfusion and hematology, new experiences, new methods, and new technologies in clinical diagnosis and treatment, introduces domestic and foreign research trends, conducts academic exchanges, and promotes the development of basic and clinical research in the field of transfusion and hematology.
