Expression of serum lncRNA CCDC18-AS1 and miR-501 in patients with HPV-infected cervical cancer and its correlation with prognosis / 国际检验医学杂志

ABSTRACT

Objective To explore the expression of serum long noncoding RNA(lncRNA)CCDC18-AS1 and microRNA-501(miR-501)in patients with human papillomavirus(HPV)-infected cervical cancer,and its correlation with prognosis.Methods A total of 78 patients with HPV-infected cervical cancer who underwent treatment in the hospital from May 2019 to May 2020 were enrolled as study group,meantime,80 patients with simple HPV infection and 81 patients with simple non-HPV infected cervical cancer were set as control group 1 and control group 2.Serum lncRNA CCDC18-AS1 and miR-501 expression levels were detected by re-al-time quantitative PCR.Then the clinical features,postoperative overall survival and progression-free surviv-al were analyzed in the study group.Results The relative expression levels of serum lncRNA CCDC18-AS1 and miR-501 in the study group were higher than those in control group 1 and control group 2(P<0.05),and the relative expression levels of serum lncRNA CCDC18-AS1 and miR-501 in control group 2 were higher than those in control group 1(P<0.05).Pearson correlation analysis showed that serum lncRNA CCDC18-AS1 and miR-501 were positively correlated in the study group(r=0.421,P<0.001).Serum lncRNA CCDC18-AS1 and miR-501 in study group were not related to age,but were related to clinical stage,differentiation de-gree,lymph node metastasis,and squamous epithelial cell antigen(P<0.05).Kaplan Meier analysis showed that the postoperative overall survival and progression-free survival of high lncRNA CCDC18-AS1 and miR-501 expression groups were shorter than those of low expression groups(P<0.05).Conclusion HPV-infec-ted cervical cancer patients have up-regulated expression of serum lncRNA CCDC18-AS1 and miR-501,and the abnormal changes are closely related to patients'clinical characteristics and postoperative survival,so the two indicators could be used as auxiliary indicators for the disease assessment and prognosis evaluation.
