Variables	Numbers		Adjusted HR^a (95% CI)
	All Cases	Deaths
Stage I
SEER	4438	818	1.00 (ref.)
ACTUR	2699	473	0.89 (0.78–1.02)
Stage II
SEER	6156	1811	1.00 (ref.)
ACTUR	2839	743	0.83 (0.75–0.92)
Stage III
SEER	5943	2733	1.00 (ref.)
ACTUR	3066	1202	0.77 (0.72–0.84)
Stage IV
SEER	5152	4662	1.00 (ref.)
ACTUR	2231	1984	0.91 (0.85–0.97)
Unknown stage
SEER	2125	967	1.00 (ref.)
ACTUR	1072	496	0.98 (0.86–1.12)

All HRs were estimated from multivariable Cox proportional hazard model with matching variables, age (as continuous variable), region of diagnosis, tumor grade, tumor location and surgery in the model. HR=Hazard ratio; CI=Confidence Interval
