¹All patients were followed up for at least 2 years;

²DFS at 36 mo demonstrated no significant difference between the groups. Follow-up time was shown as median (range); a: Shown as interquartile range; b: Calculated by excluding stage IA and missed follow-up patients. DFS: Disease-free survival; OS: Overall survival; NR: Not reported.
