Univariate analysis for Overall survival (OS) and Disease-free survival (DFS).

	Univariate analysis
	Hazard ratio (95%CI)	p. value
Prognostic factors for OS
Risk score (High vs Low)	2 (1.3–3)	0.0014
Age (<70 vs ≥70)	1.6 (1.1–2.4)	0.016
TMN stage (T1–T2 vs T3–T4)	2.1 (1.1–4)	0.019
TMN stage (M0 vs M1)	1.1 (0.33–3.5)	0.89
TMN stage (N0 vs N1–N1b)	2.2 (1.3–3.6)	0.0026
Grade (G1–G2 vs G3–G4)	2.4 (1.1–5.3)	0.025
Stage (I–II vs III–IV)	1.6 (1–2.4)	0.038
Prognostic factors for DFS
Risk score (High vs Low)	1.5 (0.94–2.3)	0.09
Age (<70 vs ≥70)	1.9 (1.2–2.9)	0.0064
TMN stage (T1–T2 vs T3–T4)	2.2 (1.2–4.2)	0.017
TMN stage (M0 vs M1)	0.94 (0.23–3.9)	0.93
TMN stage (N0 vs N1–N1b)	1.8 (1.1–2.9)	0.018
Grade (G1–G2 vs G3–G4)	2.8 (1.3–6.1)	0.012
Stage (I–II vs III–IV)	1.8 (1.1–2.8)	0.012

The difference is analyzed by Cox-regression analysis.
