    Abstract:
    OBJECTIVE: To explore the clinical significance of squamous cell carcinoma antigen (SCC-Ag) in the diagnosis, treatment and prognosis of cervical squamous cell carcinoma. METHODS: The serum SCC-Ag concentrations were measured for 1195 patients with cervical squamous cell carcinoma, 54 patients with non-squamous cell type cervical cancer, 325 patients with cervical intraepithelial neoplasm and 69 healthy women treated at Gynecology Ward of Shengjing Hospital, China Medical University from August 2008 to October 2010. And the correlations with their clinical pathological features of squamous cell carcinoma were analyzed and the changes in the diagnosis, treatment and prognosis monitored. RESULTS: Serum SCC-Ag in patients with cervical squamous cell carcinoma showed a sensitivity of 62.32% and a specificity of 90.10% with the optimal cutoff point of diagnosis at 1.45 µg/L. The differences of pretreatment serum SCC-Ag levels were statistically significant in clinical stage, histological differentiation, depth of invasion and lymph node metastasis (P < 0.01). The posttreatment serum SCC-Ag levels of 106 patients undergoing radical surgery and 264 patients on chemotherapy significantly decreased and were significant different with their pretreatment levels (P < 0.05). There was no relationship of serum SCC-Ag levels and human papillomavirus (HPV) opportunistic infection (all P > 0.05). The best threshold values of pretreatment serum SCC-Ag concentration for predicting early postoperative cervical lymph node metastasis and prognosis of cervical cancer were 2.15 and 12.1 µg/L respectively. CONCLUSION: As a relatively specific tumor maker for cervical squamous cell carcinoma, squamous cell carcinoma antigen is correlated with clinicopathological features of cervical squamous cell carcinoma. And it has important clinical reference values in the diagnosis, prognosis, follow-up evaluation and treatment monitoring of cervical squamous cell carcinoma.
