Survival curves stratified according to age and carcinoembryonic antigen expression. a, b The overall survival (OS) and relapse-free survival (RFS) curves with 5-year survival rates are shown according to ages of ≥70 years and < 70 years (5-year OS rate: 30.9% vs. 61.5%, log-rank P = 0.0159; 5-year RFS rate: 29.8% vs. 41.7%, log-rank P = 0.9543). c, d The OS and RFS curves with 5-year survival rates according to normal and abnormal expression of carcinoembryonic antigen (CEA; 5-year OS rate: 43.4% vs. 47.8%, log-rank P = 0.534; 5-year RFS rate: 25.2% vs. 64.7%, log-rank P = 0.0035). *P < 0.05
