Multivariate Cox proportional hazard models for predicting overall survival of late recurrence.

Characteristics	Multivariate analysis
	HR (95 % CI)	P value
Distant disease-free survival (≥7 years)	0.24 (0.072–0.81)	0.021
PFS	0.96 (0.89–1.04)	0.396
Response to first-line treatment (Long PFS group)	0.072(0.0058–0.90)	0.041

HR, hazard ratio; CI, confidence interval; PFS, progression-free survival.
