摘要: 目的 探讨长链非编码RNA(lncRNA)小核仁RNA宿主基因15(SNHG15)在胃癌中的临床意义。方法 选取行根治性手术治疗的胃癌患者97例。收集所有患者的临床资料,采用实时荧光定量聚合酶链反应(PCR)检测胃癌组织和正常胃黏膜组织SNHG15的相对表达量。对所有患者从术后第1天起随访5年。采用Kaplan-Meier生存曲线分析患者术后生存期,采用Cox比例风险模型对预后影响因素进行分析。结果 胃癌组织SNHG15相对表达量显著高于正常胃黏膜组织(P<0.001)。不同分化程度、TNM分期、浸润深度和淋巴结转移患者之间胃癌组织SNHG15相对表达量差异均有统计学意义(P<0.05)。Kaplan-Meier生存曲线分析结果显示,低表达组(SNHG15≤2.18)平均生存时间和5年生存率均高于高表达组(SNHG15>2.18)(P<0.001)。Cox比例风险模型分析结果显示,低分化、TNM分期Ⅲ~Ⅳ期、淋巴结转移和SNHG15高表达是影响胃癌患者预后的危险因素[风险比(HR)分别为0.381、2.568、2.892和4.851]。结论 胃癌组织中SNHG15表达显著升高,且与患者预后有关,或可作为胃癌机制研究及预后评估的潜在标志物。

Abstract: Objective To investigate the clinical significance of long non-coding RNA(lncRNA) small nuclear RNA host gene 15(SNHG15) in gastric cancer. Methods A total of 97 patients with gastric cancer who underwent elective radical surgery were enrolled. The clinical data of all the patients were collected,and real-time quantitative polymerase chain reaction(PCR) was used to determine the relative expression levels of SNHG15 in gastric cancer tissue and normal gastric mucosal tissue. All the patients were followed up for 5 years from the 1st day after the operation. Survival analysis was performed by Kaplan-Meier survival curve,and prognostic factors were analyzed by Cox proportional hazard model. Results The relative expression level of SNHG15 in gastric cancer tissue was higher than that in normal gastric mucosal tissue(P<0.001). The differences of the relative expression levels of SNHG15 in gastric cancer tissues with different degree of differentiation,TNM stage,depth of invasion and lymph node metastasis had statistical significance(P<0.05). Kaplan-Meier survival curve analysis showed that the average survival time and 5-year survival rate of patients in low expression(SNHG15≤2.18) group were higher than those in high expression(SNHG15>2.18) group(P<0.001). Cox proportional hazard model analysis showed that poorly differentiation,TNM stage Ⅲ-Ⅳ,lymph node metastasis and the expression of SNHG15 were risk factors that affected the prognosis of gastric cancer patients [hazard ratios(HR) were 0.381,2.568,2.892 and 4.851]. Conclusions The expression of SNHG15 in gastric cancer tissues is increased significantly,and it is related to the prognosis of patients,or can be used as a potential marker for gastric cancer mechanism research and prognosis evaluation.
