In the investigation of risk factors for mortality in cervical cancer, both univariate and multivariate analyses revealed that late stage of diagnosis (HR, 6.062; 95% CI, 1.43-25.69; P= 0.014 and HR, 12.397; 95% CI, 1.43-25.69; P= 0.043, respectively), HPV negativity (HR, 6.744; 95% CI, 2.02-22.47; P= 0.002 and HR, 15.663; 95% CI, 2.02-22.46; P= 0.011, respectively) and low CD8+/CD4+ ratio (HR, 5.272; 95% CI, 1.14-24.43; P= 0.034 and HR, 11.898; 95% CI, 1.14-24.43; P= 0.011, respectively) associate with shorter overall survival (Table 3). Here, CD4 is linked to cervical cancer.
