ABSTRACT
BACKGROUND:
Cyclooxygenase-2 (Cox-2) is frequently overexpressed in cervical carcinoma, but little is known about its altered serum concentration. Hence, this study evaluates clinical utility of cellular and serum level of Cox-2 enzyme in cervical cancer.METHODS:
The expression of Cox-2 was evaluated in cervical tissues and serum samples collected from normal controls (n = 100; n = 68), cervical intraepithelial neoplasia patients (CIN, n = 67; n = 12), and invasive squamous cell carcinoma patients (SCCs; n = 153; n = 127) by immunohistochemical and enzyme-linked immunosorbent assay (ELISA) analyses.RESULTS:
The significant cytoplasmic overexpression of Cox-2 was noted in 50.7% of CIN and 69.9% of SCCs as compared with normal (P = 0.0001). Serum level of Cox-2 was also found to be elevated both in CIN (median 4.35 ng/ml) and in SCCs (median 19.39 ng/ml) with respect to normal (median 0.44 ng/ml; P = 0.0001), respectively. The ROC analysis revealed the potential of serum Cox-2 over its cellular expression to distinguish CIN and SCCs from normal.CONCLUSION:
Augmented Cox-2 activity is implicated in the pathogenesis of cervical cancer, and its serum level could serve a potential to distinguish this malignancy. Therefore, it is suggested that serum Cox-2 may be useful in monitoring the diagnosis and treatment outcome of patients.Palavras-chave
