Significance of PTPRZ1 and CIN85 expression in cervical carcinoma.

To investigate PTPRZ1 and CIN85 expression and their significance in cervical carcinoma. The expression of PTPRZ1 and CIN85 was detected by immunohistochemistry and the association between PTPRZ1 and CIN85 expression and clinical pathological variables were analyzed. The expression of PTPRZ1 and CIN85 were significantly higher in cervical carcinoma than those in normal cervical epithelium. CIN85 expression was significantly higher in patients with deeper cervical invasion when compared with that with superficial invasion, while PTPRZ1 expression was significantly higher in patients with smaller tumor size (≤2 cm) than that with larger size (>2 cm). The expression of PTPRZ1 and CIN85 were higher in squamous cell carcinoma than those in adenocarcinoma. There exist increased PTPRZ1 and CIN85 expression in cervical carcinoma and they are probably associated with tumor growth or invasion. PTPRZ1 and CIN85 expression were higher in squamous cell carcinoma than those in adenocarcinoma.
