Expression of RET gene in cervical squamous cell carcinoma / 实用医学杂志

ABSTRACT

Objective To explore the expression of RET in cervical squamous carcinoma tissues and evaluate its relationship with cervical squamous carcinoma clinical pathological indexes and its prognostic value. Methods The expression and distribution of RET in normal cervical tissues ,CINⅠ,CINⅡ& CINⅢ and cervical squamous carcinomas tissues were detected by immunohistochemistry in wax blocks. Clinical data and follow-up data are integrated to analyze its relationship with clinical pathological factors and prognosis value. Results The positive rate of RET protein in cervical squamous carcinomas tissues is higher than in other tissues.The positive rate was related to FIGO stage and lymph node metastasis(P0.05). The result of survival analysis with Kaplan-Meier method showed poorer disease-free survival time in the patients with high expression of RET (P < 0.05). Prognostic analysis of patients with cervical cancer through COX proportional hazard regression model suggested that RET expression was an independent prognostic factor. Conclusions RET has been involved in the progression ,FIGO stage and metastasis of cervical squamous cell carcinomas.
