Tumor microenvironment plays an essential role during the progression of hepatocellular carcinoma (HCC). Tumor infiltrating immune cells (TILs) was an important component of tumor microenvironment. However, whether TIL features are correlated with the prognosis of HCC patients remains unclear.
Cancer tissue and paired paracancerous tissues from 220 stage II∼III HBV-related HCC patients were collected. TILs were analyzed using a tyramide signal amplification system combined with immunohistochemistry. Kaplan-Meier survival analysis was conducted to investigate the associations between the prognosis and the infiltrating pattern of TILs.
The patients were classified into three distinct subgroups (Clusters (C)1-3) with different overall survival (OS) and disease-free survival (DFS) according to the distribution pattern of TILs. The CD68/CD8 ratio in the cancer SA was correlated with the prognosis. Patients with a higher CD68/CD8 ratio exhibited poorer OS and DFS than those with a lower ratio. The CD68/CD8 ratio in the cancer SA was an independent factor for OS prediction but not DFS.
CD68+ macrophages and CD8+ T-cells are essential immunological determinants for HBV-related HCC prognosis, and the CD68/CD8 ratio in cancer SA is a novel, prognostic factor for OS prediction in HBV-related HCC patients.
肿瘤微环境在肝细胞癌（HCC）的进展中起着至关重要的作用。肿瘤浸润免疫细胞（TILs）是肿瘤微环境的重要组成部分。然而，TIL 的特征是否与 HCC 患者的预后相关尚不清楚。
收集了 220 例乙型肝炎病毒（HBV）相关的 II∼III 期 HCC 患者的癌组织和配对癌旁组织。使用酪胺信号放大系统结合免疫组织化学法分析 TILs。采用 Kaplan-Meier 生存分析探讨 TIL 浸润模式与预后之间的关系。
根据 TIL 分布模式，患者被分为三个不同的亚组（簇（C）1-3），具有不同的总生存期（OS）和无病生存期（DFS）。癌症 SA 中的 CD68/CD8 比值与预后相关。CD68/CD8 比值较高的患者 OS 和 DFS 较比值较低的患者差。癌症 SA 中的 CD68/CD8 比值是 OS 预测的独立因素，但不是 DFS 的独立因素。
CD68+巨噬细胞和 CD8+T 细胞是 HBV 相关 HCC 预后的重要免疫学决定因素，癌症 SA 中的 CD68/CD8 比值是预测 HBV 相关 HCC 患者 OS 的一个新的预后因素。
