Table 1.
Comparisons of the clinicopathological features between Groups Y and O with colorectal cancer.
Fig 1.
Five-year overall survival rates in Groups Y and O.
There was no difference in 5-year overall survival significantly between Group Y and O. Group Y, patients ≤50 years; Group O, patients > 50 years (Group Y, 86.8%; Group O, 82.7%; P = 0.459).
Fig 2.
Progression-free survival in patients with stage IV colorectal cancer.
The median progression-free survival in stage IV cases was significantly shorter in Group Y. Group Y, patients ≤50 years; Group O, patients >50 years (Group Y (8 months) vs. Group O (14 months); P = 0.002).
