Table 2. Multivariate analysis of prognostic factors of the study population.

Unfavorable factor Hazard ratio (HR) 95% CI of HR ?2 p-values
Lymph nodes metastasis Positive 8.97 2.28 to 35.31 0.002
Foxp3+ cancer cells High 1.09 1.02 to 1.14 0.006

Lymph node metastasis (N category) and Foxp3+ were found to be prognostic parameters of survival (p<0.01, Chi-Quadrat).
