摘　　要：目的探讨转录因子SOX2在非小细胞肺癌(NSCLC)中的表达与其临床病理特征及预后间的联系。方法收集2017年1月—2019年5月成都医学院第一附属医院行手术切除并经病理科确诊的NSCLC标本74例。采用免疫组织化学法检测SOX2在NSCLC组织及癌旁组织的表达情况,并分析其临床病理特征及患者预后。结果NSCLC组织SOX2阳性表达率高于癌旁组织,差异有高度统计学意义(P<0.01)。不同组织学类型、有无淋巴结转移、不同临床分期SOX2阳性率比较,差异有统计学意义(P<0.05或P<0.01)。本研究从2017年4月开始随访,随访截至2020年4月。SOX2阳性表达的NSCLC患者生存期长于SOX2阴性表达者,差异有高度统计学意义(P<0.01)。SOX2阳性表达及淋巴结转移是NSCLC患者预后的独立影响因素(RR>1,P<0.05)。结论NSCLC组织中SOX2表达和组织学类型及临床分期相关,可作为NSCLC诊断及判断预后的潜在生物标志物。Objective To investigate the expression between transcription factor SOX2 in non-small cell lung cancer(NSCLC)and association clinicopathological characteristics and prognosis.Methods From January 2017 to May 2019,74 NSCLC specimens were collected from the First Affiliated Hospital of Chengdu Medical College and confirmed by the pathology department.Immunohistochemistry was used to detect the expression of SOX2 in NSCLC tissues and paracancerous tissues,and its clinicopathological characteristics and the prognosis of patients were analyzed.Results The positive rate of SOX2 in NSCLC tissues was higher than that in paracarcinoma tissues,and the difference was highly statistically significant(P<0.01).There were statistically significant differences in SOX2 positive rate among different histological types,lymph node metastasis and clinical stages(P<0.05 or P<0.01).This study was followed up from April 2017,and follow-up was conducted up to April 2020.NSCLC patients with SOX2 positive expression lived longer than that with SOX2 negative expression,and the difference was highly statistically significant(P<0.01).SOX2 positive expression and lymph node metastasis were independent influence factors in prognosis of patients with NSCLC(RR>1,P<0.05).Conclusion SOX2 expression in NSCLC tissues is related to histological type and clinical stage,which can be used as a potential biomarker for diagnosis and prognosis of NSCLC.
