Abstract
Objective To explore the expression of Smad2 in cervical carcinoma and analyze the clinical significance of Smad2.Methods The expression of Smad2 in normal uterus group( NE group,n =61 ) and cervical carcinoma group( CC group,n =53 ) were detected by immunohistochemistry to analyze the significance of Smad2 in the cervical carcinoma.Results Positive rate of expression of Smad2 protein in NE group was 39.3％,positive rate was 77.4％ in CC group,statistical difference was found between the two groups(P ＜ 0.01 ).The degree of differentiation of cervical cancer was lower,and the Smad2 positive rate was higher,well-differentiated and poorly differentiated were 52.6％ and 91.2％,respectively,and the difference was statistically significante ( P ＜ 0.01 ) ; The invasion of cancer was higher,and the Smad2-positive rate was higher ≤ 1/2 and ＞ 1/2 were 66.7％ and 91.3％,respectively,and the difference was statistically significante ( P ＜ 0.05 ).Conclusion The expression of Smad2 was less; Smad2 was related to depth of invasion and degree of differentiation of cervical carcinoma,which could be used as clinical diagnosis and prognostic markers. Key words: Uterine cervical neoplasms; Smad2 protein ; Immunohistochemistry
