Patient characteristics with a statistically significant association with survival variables

	Survival variable
	DDFS	DFS	OS
Tumor stage at baseline
T1, %	100	97.4	100
Other, %	75	72.5	82.5
Log rank p	0.0001	0.001	0.006
Nodal status at baseline
Negative, %	97.4	94.7
Positive, %	77.5	75.0
Log rank p	0.012	0.023

DDFS = Distant disease-free survival, DFS = disease-free survival, OS = overall survival.
