  1. Abbreviation: No., number of the patients; HR, hazard ratio; CI; confidence interval.
  2. Multivariate analysis was adjusted for age, histological types, residual tumor and RECQL1 expression status except for lymph nodes status because number of the patients who underwent lymph node dissection was insufficient.
