Clinical evaluation of p16INK4a immunocytology in cervical cancer screening: A population-based cross-sectional study from rural China.

With minimal colposcopy referrals, p16INK4a screening demonstrated promising utility for risk stratification and yielded a better balance between sensitivity and specificity compared with HPV and LBC primary screening. Moreover, with accuracy and efficiency similar to what is achieved using mainstream cotest algorithms, p16 may simplify the screening practice. More evidence will be required before clinical recommendation.
