Effects of two genes coding squamous cell carcinoma antigen on the diagnosis and treatment of cervical squamous cell carcinoma

摘要

>Objective: To study the effects of expressions of SCCA1 and SCCA2 in cervical squamous cell carcinoma on its diagnosis, treatment evaluation and prognosis analysis. >M >ethod >s >: Seventy-six cervical squamous cell carcinoma patients enrolled in our hospital from October 2011 to April 2013 were selected, and another 76 healthy females (without cervical tissue lesions) were enrolled as the control. SCCA1 and SCCA2 expressions in the two groups were compared by RT-PCR. The serodiagnosis results before and after chemotherapy were compared to clarify the effects of SCCA2 expression. >Results: The two groups had similar relative SCCA1 expression rates that were not significantly correlated with pathological factors. Before chemotherapy, the relative expression rates of SCCA2 were significantly higher in the patients with later stage (t=6.018, P=0.00082<0.05) and lymphatic metastasis (t=6.281, P=0.00192<0.05). After treatment, relative SCCA2 expression rate was decreased more significantly in the effective group than that in the ineffective group (t=10.27893, P=0.02815<0.05). >Conclusion: The expression of SCCA1 failed to indicate the onset, diagnosis and prevention of cervical squamous cell carcinoma, whereas that of SCCA2 worked as one of the tumor markers.
