Abstract:
Objective The aim of this study was to analyze the expression of RIZ 1 and its association with clinicopathological factors or radiosensitivity in cervical squamous cell carcinoma.Methods 159 samples from patients with FIGO stage Ⅱb and Ⅲa cervical squamous cell carcinoma were collected and preserved be-fore radiotherapy.The expression of RIZ1 in cervical squamous cell carcinoma tissues and 20 normal cervical tis-sues was assessed by immunohistochemistry.The relationship between the RIZ1 expression and the clinicopatho-logical factors or radiosensitivity in cervical squamous cell carcinoma was analyzed by statistical analysis.Results The expression of RIZ1 protein was down-regulated in patients with cervical cancer(P<0.001).The level of RIZ1 protein expression was close related to radiosensitivity(P=0.012),FIGO staging(P=0.004),deep myo-metrial invasion(P=0.026),and pelvic lymph node metastasis(P=0.005).Logistic regression analysis showed that the high expression of RIZ1protein was an independent predictor of radiosensitivity in cervical cancer(P=0.045).Conc lusion RIZ1 may be involved in the occurrence and development process of cervical squamous cell carcinoma and regard as a candidate biomarker for the sensitivity in cervical squamous cell carcinoma in ra-diotherapy.
