- *1: Multivariate hazard ratios, 95% confidence intervals, and P values were adjusted for age at diagnosis (years), gender, calendar month of blood sampling, cancer stage (I, II, III, and IV), residual tumor after surgery (R0, no residual tumor; R1, microscopic residual tumor; R2, macroscopic residual tumor), time period of surgery (between 2003 and 2005 or between 2006 and 2008), and number of lymph nodes with metastasis.
- *2: Lymph nodes were resected at surgery and metastases in lymph nodes were confirmed pathologically.
