Multivariate analysis	Category compared	HR (95% CI)	P value
Disease-free survival
Tumor location	Upper vs. middle and lower	0.474 (0.228-0.987)	0.046
pTNM stage	I, II vs. III	1.892 (1.104-3.241)	0.02
Intratumoral neutrophils	<18.5 vs. ≥18.5	2.174 (1.249-3.784)	0.006
Overall survival
pTNM stage	I, II vs. III	2.122 (1.205-3.736)	0.009
Treatment regimens	Surgery alone vs. Adjuvant radiation	1.855 (1.061-3.244)	0.03
Intratumoral neutrophils	<18.5 vs. ≥18.5	1.858 (1.038-3.325)	0.037
