收集2017年3月至2019年2月海南医学院第二附属医院子宫内膜癌病人(子宫内膜癌组)82例;同时收集子宫内膜不典型增生病人(不典型增生组)67例及健康体检者(对照组)79例。采用实时荧光定量逆转录聚合酶链式反应(qRT-PCR)检测血清LINC00511、miR-515-5p表达水平;采用Pearson相关分析子宫内膜癌病人血清LINC00511与miR-515-5p表达水平的相关性;采用Kaplan-Meier法分析子宫内膜癌病人血清LINC00511、miR-515-5p表达水平与预后的关系;多因素Cox回归分析影响子宫内膜癌病人预后的因素。结果 对照组、不典型增生组、子宫内膜癌组血清LINC00511表达水平(1.020.21、1.820.31、2.600.45)依次升高,miR-515-5p表达水平(1.010.20、0.700.18、0.420.16)依次降低(P0.05)。肌层浸润深度1/2、有淋巴结转移、临床分期期的子宫内膜癌病人血清LINC00511表达水平高于肌层浸润深度1/2、无淋巴结转移、临床分期I期病人,miR-515-5p表达水平低于肌层浸润深度1/2、无淋巴结转移、临床分期期病人(P0.05)。子宫内膜癌病人血清 LINC00511 与 miR-515-5p 表达水平呈负相关(r=0.48,P0.05)。子宫内膜癌病人血清LINC00511高表达病人3年生存率低于LINC00511低表达病人(P0.05);miR-515-5p高表达病人3年生存率高于miR-515-5p低表达病人(P0.05)。LINC00511、临床分期是子宫内膜癌病人3年内死亡的独立危险因素(P0.05),miR-515-5p是子宫内膜癌病人3年内死亡的保护因素(P0.05)。结论 子宫内膜癌病人血清LINC00511表达上调,miR-515-5p表达下调,二者均与肌层浸润深度、淋巴结转移、临床分期及预后有关。关键词:子宫内膜肿瘤;长基因间非编码RNA00511;微RNA-515-5p;临床病理特征;预后临床医学1590网络首发时间:2023-07-06 13:11:16网络首发地址:https:/ 徽 医 药 Anhui Medical and Pharmaceutical

clinicopathological features and prognosis of patients with endometrial cancer.Methods Eighty-two patients with endometrial cancer(endometrial cancer group)in the Second Affiliated Hospital of Hainan Medical University from March 2017 to February 2019 were collected.Meanwhile,67 patients with atypical endometrial hyperplasia(atypical hyperplasia group)and 79 healthy people(control group)were collected.QRT-PCR method was performed to detect the expression levels of serum LINC00511 and miR-515-5p;Pearson correlation was performed to analyze the correlation between serum LINC00511 and miR-515-5p expression levels in patients with endometrial cancer;Kaplan-Meier method was performed to analyze the relationship between the expression levels of serum LINC00511 and miR-515-5p and prognosis in patients with endometrial cancer;multivariate Cox regression was performed to analyze the prognostic factors in patients with endometrial cancer.Results The expression level of serum LINC00511(1.020.21,1.820.31,2.600.45)in the control group,the dysplasia group and the endometrial cancer group was increased sequentially,and the expression level of miR-515-5p(1.010.20,0.700.18,0.420.16)was decreased sequentially(P0.05).The expression level of serum LINC00511 in endometrial cancer patients with myometrial invasion depth 1/2,lymph node metastasis and clinical stage-was higher than that in patients with myometrial invasion depth1/2,no lymph node metastasis and clinical stage-,and the expression level of miR-515-5p was lower than that in patients with myometrial invasion depth1/2,no lymph node metastasis and clinical stage-(P0.05).Serum LINC00511 in patients with endometrial cancer was negatively correlated with the expression level of miR-515-5p(r=0.48,P0.05).The 3-year survival rate of patients with high serum LINC00511 expression in patients with endometrial cancer was lower than that in patients with low LINC00511 expression(P0.05);the 3-year survival rate of patients with high miR-515-5p expression was higher than that of patients with low miR-515-5p expression(P0.05).LINC00511 and clinical stage were independent risk factors for death within 3 years in patients with endometrial cancer(P0.05),and miR-515-5p was a protective factor for death within 3 years in patients with endometrial cancer(P18周岁,资料完整且配合度高;首次确诊,所有病人术前未进行放化疗及其他抗肿瘤治1591安 徽 医 药 Anhui Medical and Pharmaceutical Journal 2023 Aug,27(8)疗;病人或其近亲属知情同意,符合 世界医学协会赫尔辛基宣言

在子宫内膜癌中的研究仍未见相关报道。本研究结果显示,LINC00511在子宫内膜癌中显著高表达,且肌层浸润较深、发生淋巴结转移、临床分期越高的病人LINC00511表达上升越明显。提示LINC00511在子宫内膜癌中发挥促癌基因作用,其可能通过高表达参与子宫内膜癌的发生发展,但目前具体机制尚不明确,推测可能与其促进肿瘤细胞恶性增殖有关。此外,本研究中子宫内膜癌病人血清miR-515-5p低表达,且与LINC00511呈显著负相关。Qiao等16研究结果显示,LINC00673可充当miR-515-5p的海绵来上调微管亲和调控蛋白激酶4表达,进而在乳腺癌中发挥促癌作用。基于既往研究结果,推测LINC00511在子宫内膜癌中发挥促癌作用可能是通过调控 miR-515-5p及相关蛋白表达而实现的,有待今后基础研究证实。部分研究17-18显示,治疗方式、临床分期、淋巴结转移、肌层浸润深度等均有可能是影响子宫内膜癌病人预后的因素,而本研究结果中仅 LINC00511、miR-515-5p、临床分期与3年生存率有关,且是影响子宫内膜癌病人预后的独立因素。表明 LINC00511、miR-515-5p的检测水平异常可提示子宫内膜癌病人不良预后,二者有可能成为评估病人预后的生物标志物。与既往研究的差异可能与研究纳入样本量、地域、纳入样本时因纳入排除标准而产生的选择偏倚等因素有关,今后将仅进一步纳入更多样本量进行验证。综上,子宫内膜癌病人血清LINC00511高表达,miR-515-5p低表达,二者与肌层浸润深度、淋巴结转移、临床分期及预后有关。LINC00511、miR-515-5p可能成为新的子宫内膜癌肿瘤标志物,但在子宫内膜癌诊断、治疗及预后评估中的具体临床应用价值仍有待大样本研究验证。且本研究随访时间相对较短,需深入研究得出更为准确的结论。参考文献1
