Objective To investigate expression and role of tissue factor pathway inhibitor -2(TFPI -2)in normal cervix,cervical intraepithelial neoplasia(CIN)and cervical squamous cell carcinoma.Methods From Janu-ary 2011 to December 2012,114 patients with cervical resection in our hospital were selected,among them,42 patients with cervical squamous cell carcinoma,27 cases with CIN,45 cases of normal cervix.Immunohistochemical method was used to detect the expression of TFPI -2 protein in cervical tissues.Results The expression of TFPI -2 in cer-vical cancer tissues was significantly lower than that in other cervical tissues,the difference was statistically significant (cervical cancer tissues vs.normal cervical tissues χ2 =59.670,P <0.05;cervical cancer tissues vs.CINⅠ χ2 =52.170,P <0.05;cervical cancer tissues vs.CINⅡ/Ⅲ χ2 =32.759,P <0.05).The expression of CIN Ⅱ/Ⅲ TFPI-2 was significantly lower than that of normal cervical tissues and CIN Ⅰ,the difference was statistically significant (χ2 =126.78,P <0.05).The expression level of TFPI -2 in normal cervix tissues and CIN Ⅰ had no statistically significant difference(χ2 =4.903,P >0.05).There was no significant difference in TFPI -2 expression in cervical cancer tissues with different differentiation levels(χ2 =4.633,P >0.05).Figo Ⅰcervical cancer TFPI -2 expression was significantly higher than Figo Ⅱ cervical cancer,the difference was statistically significant(χ2 =6.509,P <0.05).The expression of TFPI -2 in cervical cancer tissues without lymph node metastasis was significantly higher than that in cervical cancer tissues with lymph node metastasis,the difference was statistically significant (χ2 =10.916,P <0.05).Conclusion The reduction of TFPI -2 expression may be involved in the development of cervi-cal cancer,and the expression of TFPI -2 is associated with the prognosis of cervical cancer.
