Association of 8-point average of plasma concentrations of 5-fluorouracil with overall survival in Japanese patients with esophageal squamous cell carcinoma. Line: patients with plasma concentrations of 5-FU of 0.114 μg/mL or more (N = 25), dotted line: patients with plasma concentration of 5-FU of less than 0.114 μg/mL (N = 24). No statistical significant difference was observed (P = 0.321, Log-rank test).
