ABSTRACT
Objective:
To evaluate the expression of ßF1 and T cell receptor (TCR)γ in T lymphoblastic lymphoma/leukemia(T-LBL/ALL), and investigate the clinicopathological features.Methods:
Fifty-one cases of T-LBL/ALL were collected at Guangdong General Hospital from 2010 to 2016, the expression of ßF1 and TCRγ was assessed by immunohistochemistry.Results:
There were 13 cases of children and adolescents, and 38 cases of adults. The expression rates of ßF1 and TCRγ were 27.5%(14/51) and 15.7%(8/51) respectively. The proportion of adults in αß T-LBL/ALL, TCR-silent T-LBL/ALL and γδ T-LBL/ALL was 7/14, 79.3%(23/29)and 8/8 respectively, and the difference was significant (P=0.023). There was no statistical difference in sex, LDH, bone marrow involvement and Ann arbor stage among these three groups(P>0.05). γδ T-LBL/ALLs included 6 cases of CD4(-)/CD8(-) phenotype, whereas αß T-LBL/ALL included 7 cases of CD4(+) /CD8(+) phenotype. There was significant difference in CD4/CD8 expression among these three groups(P<0.01).Conclusions:
γδ T-LBL/ALL occurred only in adults, with predominantly CD4(-)/CD8(-) phenotype. αß T-LBL/ALL occurred more common in children and adolescents, with predominantly CD4(+) /CD8(+) phenotype.Palavras-chave
