目的:通过检测三阴性乳腺癌(triple-negative breast cancer,TNBC)组织中肿瘤相关中性粒细胞(tumor-associated neutrophils,TANs)浸润密度及程序性死亡配体-1(PD-L1)的表达情况来分析二者的相关性,并探究其临床意义。方法:选取141例我...目的:通过检测三阴性乳腺癌(triple-negative breast cancer,TNBC)组织中肿瘤相关中性粒细胞(tumor-associated neutrophils,TANs)浸润密度及程序性死亡配体-1(PD-L1)的表达情况来分析二者的相关性,并探究其临床意义。方法:选取141例我院三阴性乳腺癌患者组织标本,使用抗体CD66b作为TANs的标记物,通过免疫组织化学法检测TNBC肿瘤组织内TANs浸润和PD-L1表达的情况。采用Pearson积差相关或Spearman等级相关分别分析TANs浸润密度和PD-L1表达与临床病理特征的相关性,以及TNBC肿瘤组织内TANs浸润密度与PD-L1阳性表达之间的相关性;采用Kaplan-Meier曲线对TNBC患者进行生存分析。结果:TANs高浸润密度与高Ki67增殖指数、高组织学分级以及淋巴结转移均呈正相关(P<0.05)。PD-L1表达与高Ki67增殖指数及高组织学分级均呈正相关(P<0.05)。TNBC中TANs的浸润密度与PD-L1阳性表达呈正相关(P<0.05)。生存分析显示,TANs浸润密度和PD-L1表达均与TNBC患者的无进展生存期呈负相关(P<0.05)。结论:TNBC肿瘤组织内TANs浸润密度和PD-L1表达与多项临床病理特征以及不良预后密切相关,这提示TANs及PD-L1可作为TNBC预后评估的重要指标,并为探索TNBC免疫治疗潜在靶点提供研究依据。展开更多

Its association with cancer progression has been observed in multiple tumor models, but evidence supporting its association with solid tumors in humans remains controversial. This study aimed to determine the clinical signiicance and prognostic value of PDCD4 in solid tumors.Methods: A systematic literature review was performed to retrieve publications with available clinical informa?tion and survival data. The eligibility of the selected articles was based on the criteria of the Dutch Cochrane Centre proposed by the Meta?analysis Of Observational Studies in Epidemiology group. Pooled odds ratios(ORs), hazard ratios(HRs), and 95% conidence intervals(CIs) for survival analysis were calculated. Publication bias was examined by Begg's and Egger's tests.Results: Clinical data of 2227 cancer patients with solid tumors from 23 studies were evaluated. PDCD4 expression was signiicantly associated with the diferentiation status of head and neck cancer(OR 4.25, 95% CI 1.87–9.66) and digestive system cancer(OR 2.87, 95% CI 1.84–4.48). Down?regulation of PDCD4 was signiicantly associated with short overall survival of patients with head and neck(HR: 3.44, 95% CI 2.38–4.98), breast(HR: 1.86, 95% CI 1.36–2.54), digestive system(HR: 2.12, 95% CI 1.75–2.56), and urinary system cancers(HR: 3.16, 95% CI 1.06–9.41).Conclusions: The current evidence suggests that PDCD4 down?regulation is involved in the progression of several types of solid tumor and is a potential marker for solid tumor prognoses. Its clinical usefulness should be conirmed by large?scale prospective studies.展开更多
