The presence of virus DNA integration into the cell genome was studied for 47 primary HPV16-positive patients with morphologically verified stage III cervical cancer. By using ROC analysis, the patients were divided into two groups: with and without HPV DNA integration into the host cell genome. The differences between the groups by the histological type, degree of tumor differentiation, and primary response to therapy were statistically insignificant. Virus DNA integration more than 7-fold reduced 5-year relapse-free survival and 1.7-fold reduced overall survival rate in comparison with patients without HPV DNA integration (p=0.0002 and p=0.05, respectively). The relative risk of adverse outcome of the disease in patients with the presence of HPV16 DNA integration increases by 4 times over a period of less than 3 years (p=0.0006) at high AUC level. The probability of earlier progression of the disease in patients with of HPV DNA integration calculated according to the Cox proportional hazards model was 85.5% (hazard ratio 5.96; p=0.002). Thus, the results suggest that the presence of HPV16 DNA integration into the cell genome is an independent factor in predicting clinical outcome of advanced cervical cancer and can serve as an effective criterion for the individual choice of treatment tactics for the patients.
