The percentages of MDSCs, IFN--producing CD4 and CD8 T cells in the peripheral blood of HCC patients, chronic hepatitis B (CHB) patients, and healthy controls (HC) were determined by flow cytometry. The serum concentrations of IL-10 and TNF- were determined by ELISA. The association of the percentages of MDSCs with tumor burden, liver function parameters, systemic inflammation-related indexes, and IFN--producing T cells was assessed.
The percentages of MDSCs and PMN-MDSCs were significantly higher in HCC patients than those in CHB patients and HC. The level of MDSCs was correlated with indirect bilirubin and prealbumin, as well as systemic inflammation response index, monocyte/lymphocyte ratio, and monocyte counts. The frequency of IFN--producing CD8 T cells of HCC patients was lower than that of HC. However, there was no relationship between MDSCs and IFN--producing CD8 T cells. The level of IL-10 in HCC patients was significantly higher than that in CHB patients.
MDSCs seem to play an important role in the process leading from chronic HBV infection to HCC. Early inhibiting these cells could affect tumor progression.
采用流式细胞术检测 HCC 患者、慢性乙型肝炎（CHB）患者和健康对照者（HC）外周血中髓系抑制细胞（MDSCs）、IFN--产生的 CD4 和 CD8 T 细胞的百分比。采用 ELISA 法检测血清中白细胞介素-10（IL-10）和肿瘤坏死因子-α（TNF-α）的浓度。评估 MDSCs 百分比与肿瘤负荷、肝功能参数、全身炎症相关指标和 IFN--产生的 T 细胞之间的相关性。
与 CHB 患者和 HC 相比，HCC 患者的 MDSCs 和 PMN-MDSCs 百分比显著升高。MDSCs 水平与间接胆红素和前白蛋白以及全身炎症反应指数、单核细胞/淋巴细胞比值和单核细胞计数相关。HCC 患者 IFN--产生的 CD8 T 细胞的频率低于 HC。然而，MDSCs 与 IFN--产生的 CD8 T 细胞之间没有关系。HCC 患者的 IL-10 水平明显高于 CHB 患者。
MDSCs 似乎在从慢性乙型肝炎病毒感染到 HCC 的发展过程中发挥重要作用。早期抑制这些细胞可能会影响肿瘤的进展。
