Variables	DFS (n=136)		OS (n=136)
	HR (95% CI)	p	HR (95% CI)	p
MIF in Tumor cells (low/high)	1.689 (1.132-2.521)	0.010*	1.619 (1.084-2.418)	0.018*
CXCR4 in Tumor cells (low/high)	1.708 (1.126-2.591)	0.012*	1.612 (1.072-2.425)	0.022*
MIF in Lymphocytes (low/high)	1.473 (0.999-2.172)	0.050*	1.523 (1.027-2.259)	0.037*
Combination of MIF and CXCR4 in tumor cells (low/mid/high)	1.338 (1.064-1.683)	0.013*	1.263 (1.009-1.583)	0.042*

Note: The Cox proportional hazards regression model contained the significantly different factors in univariate analysis, including gender, WHO grade, T status, N status and TNM stage. HR, hazard ratio; CI, confidence interval; * means P < 0.05.
