To investigate the relationship between E-cadherin, beta-catenin, N-cadherin, ZEB1, and αSMA as epithelial-mesenchymal transformation markers with tumor stage, lymph node metastasis (LNM), and overall survival (OS) in laryngeal squamous cell carcinomas (LSCC).
A total of 100 cases diagnosed with LSCC were included in the study. Data about the lymphovascular invasion (LVI), perineural invasion (PNI), necrosis, and LNM were recorded by evaluating hematoxylin-eosin-stained slides. Markers of E-cadherin, beta-catenin, N-cadherin, ZEB1, and αSMA were applied to the sections prepared from paraffin blocks of tumor samples.
Ninety-five male and five female patients were included in the study, and 38 of them exited. A significant relationship was observed between OS with advanced tumor stage, presence of LNM and PNI. A significant relationship was found between increased tumor Zeb1 expression and advanced tumor stage. In univariate and multivariate analyses, a significant negative relationship with OS, and increased Zeb1 expression in tumor and tumor stroma was seen. Any relationship was not observed between E-cadherin, beta-catenin, N-cadherin, and αSMA and OS.
Among the EMT markers, we evaluated in our study, it was seen that Zeb1, which is an EMT transcription factor, is associated with tumor stage, LNM, and OS. Remarkably, Zeb1 expression observed in tumor stroma was also significant for OS. Any similar data reported for LSCCs have not been encountered in the literature, and it was thought that it would be appropriate to support our findings with further studies to be performed on this subject.
研究作为上皮-间质转化标志物的E-钙黏蛋白、β-连环蛋白、N-钙黏蛋白、锌指E盒结合蛋白1(ZEB1)和α平滑肌肌动蛋白(αSMA)与喉鳞状细胞癌(LSCC)的肿瘤分期、淋巴结转移(LNM)及总生存期(OS)之间的关系。
本研究共纳入100例确诊为LSCC的病例。通过评估苏木精-伊红染色切片记录有关脉管侵犯(LVI)、神经周侵犯(PNI)、坏死及LNM的数据。将E-钙黏蛋白、β-连环蛋白、N-钙黏蛋白、ZEB1和αSMA标志物应用于肿瘤样本石蜡块制备的切片。
本研究纳入95例男性和5例女性患者,其中38例退出研究。观察到OS与晚期肿瘤分期、LNM及PNI的存在之间存在显著关系。发现肿瘤Zeb1表达增加与晚期肿瘤分期之间存在显著关系。在单因素和多因素分析中,可见与OS呈显著负相关,且肿瘤和肿瘤间质中Zeb1表达增加。未观察到E-钙黏蛋白、β-连环蛋白、N-钙黏蛋白和αSMA与OS之间存在任何关系。
在我们研究中评估的上皮-间质转化标志物中,可见作为上皮-间质转化转录因子的Zeb1与肿瘤分期、LNM及OS相关。值得注意的是,在肿瘤间质中观察到的Zeb1表达对OS也具有重要意义。文献中未遇到有关LSCC的任何类似数据,认为通过对该主题进行进一步研究来支持我们的发现是合适的。
