The immune interactions occurring within the tumor microenvironment have a critical role in determining the outcome of colorectal cancer patients. We carried-out an immunohistochemical analysis of tumor infiltrating T-lymphocytes expressing chemokine receptor 7 (CCR7) in a series of colorectal cancer patients enrolled in a prospective clinical trial. We demonstrated that a high tumor infiltration score of this lymphocyte subset is predictive of longer progression free survival and overall survival.
肿瘤微环境中发生的免疫相互作用在决定结直肠癌患者的结局方面起着关键作用。我们对参加前瞻性临床试验的一系列结直肠癌患者的肿瘤浸润 T 淋巴细胞表达趋化因子受体 7(CCR7)进行了免疫组织化学分析。我们证明,这种淋巴细胞亚群的高肿瘤浸润评分可预测更长的无进展生存期和总生存期。
