Clinical Significance of Serum CircNRIP1 Expression in Diagnosis and Treatment of Gastric Cancer / 胃肠病学

ABSTRACT

Background: Circular RNAs (circRNAs) is correlated with the development and progression of malignant tumor. Recent studies have shown the potentials of some circRNAs in the early diagnosis, screening of therapeutic targets and prognostic judgment of gastric cancer. Aims: To investigate the serum circNRIP1 expression and its clinical significance in the diagnosis, treatment and prediction of prognosis of gastric cancer. Methods: A total of 76 gastric cancer patients diagnosed by pathology from September 2016 to September 2019 at Dujiangyan People's Hospital were enrolled, and 63 healthy individuals were served as controls. Serum circNRIP1 expression was detected by real time fluorescent quantitative PCR, and its correlation with clinicopathological features was analyzed. ROC curve was used to analyze the diagnostic efficiency. Results: Serum circNRIP1 expression in gastric cancer group was significantly higher than that in healthy control group (P<0.01). The circNRIP1 expression in gastric cancer patients was significantly correlated with the differentiation of tumor cells, depth of infiltration, lymph node metastasis and TNM stage (P<0.05). Serum circNRIP1 expression in gastric cancer patients after operative treatment was significantly lower than that before treatment (P<0.05). After 2 years follow-up, serum circNRIP1 expression in survival group was significantly lower than that in death group (P<0.05). ROC curve analysis showed that the sensitivity of serum circNRIP1 expression for gastric cancer was 88.9%, the specificity was 88.2%, and AUC was 0.876. Conclusions: Detecting serum circNRIP1 expression has significant value in the early diagnosis and evaluation of treatment and prediction of prognosis of gastric cancer.
