Survival curve based on the expression of SCCA (A) prior to and (B) following chemotherapy, and (C) chemotherapy sensitivity. No significant differences were observed in the cumulative survival rate between patients with positive and negative SCCA expression prior to chemotherapy (A; P=0.211). However, significant differences between these groups were identified following chemotherapy (B; P=0.009). No significant difference was observed in the cumulative survival rate between patients with chemotherapy-sensitive and chemotherapy-resistant cancer (P=0.698; Fig. 2C). SCCA, squamous cell carcinoma antigen.
