Abstract:
Objective To explore the clinical significance of detection of plasma microRNA-21,-143 in identifying early esophageal cancer and esophageal non-tumor diseases.Methods The expression of plasma microRNA-21,-143 in 27 cases of patients with early esophageal cancer (esophagus cancer group),25 cases of patients with non-esophageal tumor (non-esophageal tumor group)and in the healthy controls were detected by RT-PCR,and detected the levels of plasma CEA and CA72-4 by the electrochemical luminescence technology,which of changes were analysed to observe the relationship between the changes and the esophageal cancer,the benign esophageal diseases for the two markers.Results The expression of plasma microRNA-21,-143 in the esophagus cancer group were 0.93±0.17,0.27±0.05,which of ones in the non-esophagus cancer group were 0.25±0.03,0.99±0.15,and with those in the control group were 0.23±0.03,1.02±0.15.Compared with those in the non-esophagus cancer group,the expression of plasma microRNA-21,-143 were obviously up or down-regulated with significant differences (t=10.87,11.55,P＜0.01).Compared with those in the control group,which of ones were obviously up or down-regulated with significant differences (t=9.20,9.07,P＜0.01),and with no statistical significances in comparison between the esophagus cancer group and the control group (t=1.39,1.19,P＞0.05).The positiverate of plasma microRNA-21,-143 in the esophageal cancer,non-esophagus cancer group and the control group were,81.4 ％ (22/27),4.0 ％(1/25) and 0 (0/24);85.1％ (23/27),4.0％ (1/25),and 0 (0/24),respectively.The positive rate of microRNA-21,-143 in the esophageal group respectively in comparison with those in the non-esophagus cancer group and the control group were significantly higher,the differences had statistical significances (x2 =31.59,34.39,P＜ 0.01;x2 =34.42,37.23,P＜ 0.01).The expression of two markers in the esophagus cancer group were no statistically significant differences compared with control group (x2 =0.980,0.980,P＞0.05).The sensitivity and specificity of microRNA-21,-143 in early diagnosis on the esophageal cancer were 81.4 ％,97.9 ％ and 85.1％,97.9 ％.The sensitivity of microRNA-21,-143 in the esophageal group were significantly higher compared with those of CEA and CA72-4,the differences were statistically significant (x2 =12.79,P＜0.01;x2 =5.33,P＜0.05;x2 =15.03,P＜0.01;x2 =6.95,P＜0.05).The specificity of microRNA-21,-143 in the esophageal cancer group were no statistically significant differences in comparison with those of CEA and CA72-4 (x2 =1.043,0.000,P＞0.05) and (x2=1.043,0.000,P＞0.05),respectively.The analysis results from the spearman correlation test showed that in the esophageal cancer group,the expression of plasma microRNA-21,-143 had a negative correlation (r =0.658,P＜0.01).Which of ones respectively associated with the levels of CEA and CA72-4 (r=0.607,0.623,P＜0.01 and r=0.579,0.610,P＜0.01).Conclution The detection of expression of plasma miRNA-21,miRNA-143 in the patients with the early esophageal cancer and non-esophageal tumor can provide a new train of thought for pathologic diagnosis of early esophageal cancer.
