Survival	Initial metastasectomy	Second metastasectomy	Third metastasectomy
Overall 5-year survival (%)	71.17	79.32	77.78^a
DFS
Median survival (months)	27.43	42.8	Not calculated^a
5-year survival (%)	33.30	48.69	Not calculated^a

^aThe number of patients that underwent third metastasectomy was too small for statistical analysis. OS, overall survival; DFS, disease-free survival.
