Abstract:
Objective To evaluate the changes of CD4+ CD25+ regulatory cells (Treg) in peripheral blood and the serum levels of transforming growth factor beta-1 (TGF-β1)in elderly patients with hepatocellular carcinoma. Methods The ratios of Treg in the peripheral blood of patients aged over 80 years from 22 hepatocellular carcinoma,26 metastatic liver cancer,20 healthy controls,were determined by flow cytometry.Meanwhile,the serum levels of TGF-β1 were detected by ELISA.Results The ratio of Treg to total CD; T cells in the peripheral blood [(9.71±3.23)% vs.(5.81±1.18)%,P<0.01]and the serum levels of TGF-β1 [(78.10±29.41)ng/L vs.(7.78± 3.54) ng/L,P<0.01]of elderly patients with hepatocellular carcinoma were significantly higher than those in the healthy controls.Meanwhile,the ratio of Treg to total CD[ T cells in the peripheral blood [(9.71±3.23)% vs.(7.36±2.07) %,P<0.05]and the serum levels of TGF-β1[(78.10± 29.41 )ng/L vs.(19.33± 10.90) ng/L,P< 0.01 ]in the patients with hepatocellular carcinoma was increased as compared with those in metastatic liver cancer (P<0.05 or P<0.01).The correlation indicated that the ratio of Treg to total CD4+ T cells in the peripheral blood were positively related with TGF-β1 levels and tumor clinical stage(r=0.698 and 0.782,P< 0.01 ),but negatively with Karnofsky performance status score(KPS) (r=-0.643,P<0.01). Conclusions The ratio of Treg to total CD4+ T cells in the peripheral blood from elderly hepatocellular carcinoma is increased and correlated with TGF-βl level,tumor clinical stage and KPS.It might helpful to determine the prognosis of elderly hepatocellular carcinoma by detecting the ratio of Treg to total CD4+ T cells in the peripheral blood.
