Previous clinical studies have found that the levels of tumor-infiltrating lymphocytes (TILs) significantly correlated with prognosis in hepatocellular carcinoma (HCC). However, these conclusions and data remain controversial. We performed a systematic review and meta-analysis to assess the prognostic value and clinical utilization of TILs in patients with HCC. A total of 23 relevant studies of 3173 patients were included into our meta-analysis. The results demonstrated that high levels of CD8 and CD3 TILs had a better prognostic value on overall survival (OS), with HRs of 0.71 (P = 0.04) and 0.63 (P = 0.03), respectively, compared to low levels, as did high levels of CD8 , CD3 and CD4 TILs on disease/recurrence-free survival (DFS/RFS), with HRs of 0.66 (P = 0.01), 0.60 (P = 0.01) and 0.79 (P = 0.04), respectively. In contrast, high levels of FoxP3 TILs had a worse prognostic value on OS and DFS/RFS, with HRs of 2.06 (P < 0.00001) and 1.77 (P < 0.00001), respectively. The FoxP3/CD4 and FoxP3/CD8 ratios negatively correlated with OS and DFS/RFS. These findings suggest that TILs may serve as a prognostic biomarker in HCC. However, further research should be performed to clarify the clinical value of TILs in HCC.
先前的临床研究发现，肿瘤浸润淋巴细胞（TILs）的水平与肝细胞癌（HCC）的预后显著相关。然而，这些结论和数据仍然存在争议。我们进行了系统的综述和荟萃分析，以评估 TILs 在 HCC 患者中的预后价值和临床应用。共有 23 项涉及 3173 名患者的相关研究被纳入我们的荟萃分析。结果表明，高水平的 CD8 和 CD3 TILs 对总生存期（OS）具有更好的预后价值，与低水平相比，风险比（HR）分别为 0.71（P=0.04）和 0.63（P=0.03），高水平的 CD8 、CD3 和 CD4 TILs 对疾病/复发无进展生存期（DFS/RFS）也具有更好的预后价值，HR 分别为 0.66（P=0.01）、0.60（P=0.01）和 0.79（P=0.04）。相比之下，高水平的 FoxP3 TILs 对 OS 和 DFS/RFS 具有更差的预后价值，HR 分别为 2.06（P<0.00001）和 1.77（P<0.00001）。FoxP3/CD4 和 FoxP3/CD8 比值与 OS 和 DFS/RFS 呈负相关。这些发现表明 TILs 可能作为 HCC 的预后生物标志物。然而，需要进一步的研究来阐明 TILs 在 HCC 中的临床价值。
