【摘要】：檢測(cè)T細(xì)胞免疫球蛋白及黏蛋白分子3(T cell immunoglobulin and mucin domain containing molecules 3,TIM-3)在胃癌患者固有免疫細(xì)胞(γδT細(xì)胞與NK細(xì)胞)中的表達(dá)率,探討其與臨床病理特征及術(shù)后中位無(wú)進(jìn)展生存期(progress free survival,PFS)的關(guān)系。收集臨床病理資料齊全的胃癌患者26例,經(jīng)流式細(xì)胞技術(shù)檢測(cè)TIM-3在胃癌組織、癌旁組織及外周血γδT細(xì)胞、NK細(xì)胞中的表達(dá)率,并分析其與臨床病理因素及中位PFS的相關(guān)性。結(jié)果發(fā)現(xiàn),TIM-3在胃癌組織和癌旁組織中γδT細(xì)胞上均表達(dá),而2類(lèi)組織中γδT細(xì)胞上TIM-3的表達(dá)率差異無(wú)統(tǒng)計(jì)學(xué)意義(P=0.074),但均顯著高于其在外周血γδT細(xì)胞上的表達(dá)水平(P0.001;P0.001)。TIM-3在外周血NK細(xì)胞中表達(dá)率較高,且TIM-3在外周血中NK細(xì)胞表達(dá)率顯著高于胃癌組織及癌旁組織(P0.001;P0.001),而癌組織與癌旁組織之間差異無(wú)統(tǒng)計(jì)學(xué)意義(P=0.097)。NK細(xì)胞中TIM-3的表達(dá)率分別與腫瘤浸潤(rùn)深度和TNM分期相關(guān)(P0.01),γδT細(xì)胞中TIM-3表達(dá)率與TNM分期有關(guān)(P0.01)。γδT細(xì)胞及NK細(xì)胞中TIM-3表達(dá)率較低的胃癌患者比TIM-3表達(dá)率較高的胃癌患者的中位PFS更長(zhǎng)(P=0.014;P=0.028),提示TIM-3在胃癌的進(jìn)展過(guò)程中起到重要作用。
[Abstract]:The expression rate of T cell immunoglobulin and mucin molecule 3 (T cell immunoglobulin and mucin domain containing molecules 3 TIM-3 in innate immune cells (緯 未 T cells and NK cells) of patients with gastric cancer was detected. To investigate its relationship with clinicopathological features and median progressive survival time (progress free survival,PFS). 26 cases of gastric cancer with complete clinicopathological data were collected. The expression rate of TIM-3 in gastric cancer tissues, peripheral blood 緯 未 T cells and NK cells was detected by flow cytometry, and the correlation with clinicopathological factors and median PFS was analyzed. The results showed that TIM-3 was expressed on 緯 未 T cells in gastric cancer and paracancerous tissues, but there was no significant difference in the expression rate of TIM-3 on 緯 未 T cells between the two types of tissues (P0. 074). The expression level of 緯 未 T cells was significantly higher than that of 緯 未 T cells (P0.001). The expression rate of TIM-3 in peripheral blood NK cells was higher than that in gastric cancer tissues and adjacent tissues (P0.001), and the expression rate of TIM-3 in peripheral blood NK cells was significantly higher than that in gastric cancer tissues and adjacent tissues (P0.001). There was no significant difference between cancer tissue and paracancerous tissue (P0. 097). NK cell TIM-3 expression was correlated with the depth of tumor invasion and TNM stage (P0. 01), respectively), but there was no significant difference between P0. 001 and paracancerous tissues (P0. 097). The expression rate of TIM-3 in 緯 未 T cells was related to the TNM stage (P0.01). The median PFS of patients with lower TIM-3 expression in 緯 未 T cells and NK cells was longer than that in patients with higher TIM-3 expression rate (P0.014). It suggests that TIM-3 plays an important role in the progression of gastric cancer.
