CD5 and CD43 expression are associate with poor prognosis in DLBCL patients

Abstract

To investigate the expression and clinical significance of CD5 and CD43 in diffuse large B cell lymphoma (DLBCL) (unspecified). Sixty-five patients with diagnosed DLBCL were enrolled. The expressions of CD5, CD43, CD10, Bcl-6 and Mun-1 were detected by immuno histochemistry. The relationship between CD5 and CD43 and clinicopathological features and prognosis of DLBCL was analyzed. In sixty-five adult DLBCL patients, 6 cases of DLBCL (9.2%) were CD5 positive, 24 cases of DLBCL (36.9%) were CD43 positive, 5 cases of DLBCL (7.7%) were both CD5 and CD43 positive. 40 cases of DLBCL (61.5%) were CD5 and CD43 negative. CD5 expression was not related to age, sex, clinical stage, type of immunophenotype (Hans typing), location, and whether infected with hepatitis B virus (HBV); CD43 expression was correlated with immunophenotyping and HBV i nfection, but was not correlated with the age, sex, clinical stage, and site. Median survival time was significantly lower in CD5-and CD43-positive DLBCL patients than CD5-and CD43-negative patien ts. The prognosis of DLBCL patients may be worse with positive CD5 and CD43 expression.
