Abstract:

Objective To investigate the roles of squamous cell carcinoma antigen(SCC-Ag),carbohydrate antigen 19-9(CA19-9) and vascular endothelial growth factor(VEGF) for chemotherapy efficacy in advanced esophageal squamous cell carcinoma. Methods Totally,112 patients with advanced esophageal squamous cell carcinoma were enrolled. All the patients were treated with docetaxel + nedaplatin. Serum levels of SCC-Ag,CA19-9 and VEGF before and after chemotherapy were determined by enzyme-linked immunosorbent assay,and the chemotherapy efficacy of SCC-Ag,CA19-9 and VEGF was evaluated by receiver operating characteristic(ROC) curve. Results The effective rate of chemotherapy in 112 patients with esophageal squamous cell carcinoma was 53.57%(60/112). There was no statistical significance in serum levels of SCC-Ag,CA19-9 and VEGF between effective chemotherapy group and ineffective chemotherapy group(P>0.05). Serum levels of SCC-Ag,CA19-9 and VEGF in effective chemotherapy group after chemotherapy were lower than those before chemotherapy(P<0.001),and serum levels of SCC-Ag,CA19-9 and VEGF in ineffective chemotherapy group after chemotherapy were higher than those before chemotherapy(P<0.001). The suppression ratios of SCC-Ag,CA19-9 and VEGF in effective chemotherapy group were higher than those in ineffective chemotherapy group(P<0.001). ROC curve analysis results showed that the area under curve(AUC) of the suppression ratios of SCC-Ag,CA19-9 and VEGF in evaluating the chemotherapy efficacy of esophageal squamous cell carcinoma were 0.741,0.712 and 0.783,the optimal cut-off values were 20%,26% and 27%,the sensitivities were 76.67%,80.00% and 83.33%,the specificities were 76.92%,73.08% and 80.77%,respectively. The AUC of the combination of the 3 factors(SCC-Ag suppression ratio >20%,CA19-9 suppression ratio >26%,VEGF suppression ratio >27%) in evaluating the chemotherapy efficacy of esophageal squamous cell carcinoma was 0.926,the sensitivity was 96.67%,and the specificity was 96.15%. Conclusions SCC-Ag,CA19-9 and VEGF can be used to evaluate the chemotherapy efficacy of advanced esophageal squamous cell carcinoma.
