Figure 3. Kaplan-Meier curves of disease-specific survival (A) and overall survival (B) according to HPV status in all OPC patients.

Figure 3

Disease-specific survival and overall survival rates were significantly better in HPV DNA-positive/mRNA-positive OPC patients than in HPV DNA-positive/mRNA-negative and HPV DNA-negative/mRNA-negative OPC patients. However, no significant differences in disease-specific survival or overall survival were found between HPV DNA-positive and HPV DNA-negative OPC patients.
