摘 要:目的观察胃癌组织中肿瘤浸润淋巴细胞(TILs)的表达,探讨其与胃癌临床病理特征的相关性及预后的影响。 方法利用光镜对956例胃癌组织中的TILs进行形态学观察。应用χ2检验分析TILs与临床病理特征的相关性,采用Kaplan-Meier生存分析和Cox回归模型分析TILs与患者生存期的关系。 结果在435例(45.5%)胃癌组织中观察到高表达的TILs,并具有特殊的组织病理形态特征。TILs的表达与肿瘤的TNM分期(P=0.000)、分化程度(P=0.000)、浸润深度(P=0.000)、大小(P=0.002)、淋巴结转移(P=0.000)、神经侵犯(P=0.005)和血管侵犯(P=0.003)有关。高表达TILs的胃癌患者预后较好,中位生存期为(69.96±2.12)个月,低表达TILs患者预后较差,中位生存期为(54.78±1.99)个月(P=0.000)。在多因素Cox回归模型中TILs[风险比(HR)=0.815,P=0.030]、患者年龄(HR=1.496,P=0.000)、TNM分期(HR=1.756,P=0.000)、血管内癌栓(HR=1.389,P=0.001)和淋巴结转移(HR=1.864,P=0.000)为独立预后因素。 结论胃癌组织中TILs可对机体起到重要的保护作用。Objective To investigate the correlation between tumor infiltrating lymphoeytes (TILs) and clinical pathological characteristics in gastric carcinoma and the effect on the prognosis. Metb- 2 otis Pathological changes of TILs in 956 cases of gastric cancer were observed by optical microscope. X test was used to analyze the correlation between TILs and the elinicopathological features, and Kaplan - Meier survival analysis and Cox regression model to analyze the relationship between the TILs and the prog- nosis of patients. Results In 435 cases (45. 5% ), TILs was observed the high degree infiltrating in gas- trie cancer and the expression of TILs had significant statistical significance with TNM stage ( P = 0. 000), tumor size ( P = 0. 002 ), differentiation degree ( P = 0. 000 ), invasion depth ( P = 0. 000 ), lymph node metastasis (P =0. 000) ,perineural invasion ( P = 0. 005 ) , andtumor thrombus ( P = 0. 003 ). TILs expression is positively related to the survival time of the patients, the median survival time was (69. 96± 2. 12)months in the patients with high expression, and the median survival time was (54.78±1.99) months in the patients with low expression ( P = 0. 000 ). TILs [ Hazard ratio (HR) = 0. 815, P = 0. 0303, age (HR = 1. 496,P =0. 000), TNM stage ( HR = 1. 756,P = 0. 000), tumor thrombus ( HR = 1. 389 ,P =0. 001 ) and lymph node metastasis (HR = 1. 864 ,P =0. 000) were independent prognostic fac-tots in Cox regression model. Conclusion TILs play an important protective role in gastric cancer patients.
