The expression and significance of Smad2 in cervical cancer tissue / 中国基层医药

ABSTRACT

ObjectiveTo explore the expression of Smad2 in cervical carcinoma and analyze the clinical significance of Smad2.MethodsThe 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.ResultsPositive 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 ).ConclusionThe 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.
