摘要
The utility of placental growth factor(PIGF)and its receptor VEGFR-1(Flt-1)as biomarkers for cervical cancer has not been clarified yet.To address this issue,we investigated the levels of soluble PIGF(sPIGF)and soluble Flt-1(sFlt-1)in the serum from patients with early cervical cancer,cervical intraepithelial neoplasia(CIN)and controls in this study.sPIGF and sFlt-1 were detected in 44 preoperative patients with cervical cancer,18 cases with CIN,and 20 controls by ELISA.It was found that both sPIGF and sFlt-1 were significantly increased in the cervical cancer group as compared with those in CIN and control groups.sPIGF presented a high diagnostic ability of cervical cancer,with a sensitivity of 61.36%and a specifcity of 89.47%;and sFlt-1 with a sensitivity of 50.00%and a specifcity of 92.I 1%。Importantly,the combined use of sPIGF and sFlt-1 could increase the diagnostic rate of cervical cancer,with a sensitivity of 70.45%and a specificity of 92.11%.These results indicated that both sPIGF and sFlt-1 in circulation can serve as possible valuable diagnostic biomarkers for cervical cancer,and the combined use of them can be more valuable to diagnose the patients with early cervical cancer.
