Cervical Cancer

Objective Cluster of differentiation (CD) 24 is a cell adhesion molecule that has been implicated in tumor invasion and metastasis of various solid tumors. The aim of this study was to explore the expression patterns of CD24 as a predictive marker for long-term survival in cervical carcinomas.

Methods A total of 144 patients diagnosed with International Federation of Gynecology and Obstetrics stage I to IV cervical carcinoma were studied, and 95 patients underwent surgical intervention. The expression of CD24 protein was studied by immunohistochemistry using tissue microarrays.

Results Overexpression of CD24 was observed in 50 (34.7%) of 144 invasive carcinomas. Patients with CD24 overexpression had poorer survival compared with that of patients with CD24 underexpression (5-year survival rate, 52.0% vs 72.3%; log rank P = 0.014). Importantly, in multivariate analysis, CD24 overexpression proved to be a significant independent predictor of short-term survival (relative risk, 1.814; P = 0.043).

Conclusions The present study suggests that CD24 overexpression is a predictor of decreased long-term survival in patients with cervical carcinoma. Therefore, immunohistochemical evaluation of CD24 expression is a potential prognostic biomarker for cervical carcinomas.
