31. The positive rates : 75% (69/92) by nested PCR-based genechips , 53% (49/92) by overexpression of p16INK4A (ISH), 44% (40/92) by high-risk HPV (ISH) Both overexpression of P16INK4A and high-risk HPV (ISH) positivity were associated with favorable prognoses and also independent prognostic factors .
