aP-values were obtained using the log-rank test. P-values in bold font indicate statistically significant differences (P<0.05). As regards tumor location, the oral side from the tracheal bifurcation was defined as the ‘upper’ location and the anal side from the tracheal bifurcation was defined as the ‘lower’ location. WDR1, WD repeat-containing protein 1; WDR1-Ab, serum anti-WDR1 antibody; N0, no lymph node metastasis; N1, lymph node metastasis exists; SCC-Ag, squamous cell carcinoma antigen; WBC, white blood cell; CRP, C-reactive protein.
