摘要 目的探讨SNCG蛋白在卵巢癌组织中的表达情况及临床意义,明确SNCG在人卵巢癌中的表达情况及其恶性程度的关系,为临床卵巢癌的诊断、治疗及预后提供理论依据。方法收集2010年1月—2015年1月石河子大学医学院第一附属医院收治的具有完整临床病理资料和石蜡切片的119例卵巢癌以及50例正常卵巢患者,用免疫组化方法检测组织中SNCG的表达情况,并分析SNCG的表达与卵巢癌患者临床病理特征及预后的关系。结果SNCG在卵巢癌组织中的表达高于正常卵巢组织(χ^(2)=73.575,P<0.001);SNCG的表达与卵巢癌患者的肿瘤分期、分化程度、淋巴结转移、达到满意减瘤术、CA125以及HE4水平相关,差异均有统计学意义(P<0.05);与卵巢癌肿瘤的原发部位、腹水、复发及化疗耐药无关,差异无统计学意义(P>0.05);SNCG的过表达与HGSOC患者的PFS、OS相关,差异有统计学意义(P<0.05);多变量Cox比例风险模型分析显示SNCG是HGSOC患者的独立预后因素,与PFS(HR=2.107,95%CI:1.014~3.795,P=0.034)、OS(HR=1.238,95%CI:0.716~1.928,P=0.047)相关。结论SNCG在卵巢癌中高表达,与患者肿瘤分期、分化程度、淋巴结转移、达到满意减瘤术、CA125以及HE4水平有关,与卵巢癌患者的复发与化疗耐药无关,SNCG蛋白的过表达可作为HGSOC患者的独立预后因素,指导临床诊治。 Objective To detect the expression of SNCG in ovarian cancer tissue and its clinical significance,to clarify the relationship between the expression of SNCG in human ovarian cancer and the degree of malignancy,so as to provide theoretical basis for the diagnosis,treatment and prognosis of clinical ovarian cancer.Methods From January 2010 to January 2015 in First Affiliated Hospital of Medical College of Shihezi University,119 patients with ovarian cancer and 50 patients with normal ovarian which had complete clinical data and paraffin section were selected.Immunohistochemical method was used to detect ovarian SNCG expression,and the expression of SNCG relationship with clinical pathological characteristics and prognosis of patients with ovarian cancer was analyzed.Results The expression of SNCG in ovarian cancer tissue was significantly higher than that in normal ovarian tissue(χ^(2)=73.575,P<0.001).SNCG expression was correlated with tumor stage,degree of differentiation,lymph node metastasis,satisfying tumor reduction,CA125 and HE4 levels in ovarian cancer patients,and the differences were statistically significant(P<0.05).It was not correlated with the tumor primary site,ascites,recurrence of ovarian tumor and chemotherapy resistance,and the differences were not statistically significant(P>0.05).The overexpression of SNCG was correlated with PFS and OS in HGSOC patients,and the differences were statistically significant(P<0.05).Analysis of multivariate Cox proportional risk model showed that SNCG was an independent prognostic factor in patients with HGSOC,related to PFS(HR=2.107,95%CI:1.014-3.795,P=0.034)and OS(HR=1.238,95%CI:0.716-1.928,P=0.047).Conclusion The high expression of SNCG in ovarian cancer is related to tumor stage,degree of differentiation,lymph node metastasis,satisfying tumor reduction,CA125 and HE4 expressions,but it is not related to the recurrence of ovarian cancer or chemotherapy resistance.The overexpression of SNCG protein can be used as an independent prognostic factor in patients with HGSOC for clinical diagnosis and treatment guidance.
