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).
