ABSTRACT
Objective@#To investigate the sorting effect of p16INK4a/Ki-67 double immunostaining method in patients with atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL) cytology results.@*Methods@#Four-hundred and twenty cases collected during April 2014 to February 2015 of cervical cytology of ASCUS (n=318) and LSIL (n=102) were selected, and residual liquid-based cytology specimens were used for p16INK4a/Ki-67 double immunostaining. The sensitivity and specificity of the detection of cervical precancerous lesions and cervical cancer were calculated, and the results were compared with high risk HPV. Taking histological follow-up as the gold standard, the test was considered positive when at least one cell exhibited p16INK4a/Ki-67 co-staining, without requirement of adjunct morphologic interpretation of positive cells.@*Results@#Further screening CIN2+ in cytology ASCUS and LSIL group , the sensitivity of p16INK4a/Ki-67 double immunostaining was slightly lower than high risk HPV (84.2% vs. 94.7%), while the specificity was higher (84.0% vs. 53.9%). For ASCUS patients, the sensitivity of p16INK4a/Ki-67 double immunostaining and high risk HPV was 82.6% and 91.3%, and the specificity was 88.8% and 63.7%, respectively. For LSIL patients, the sensitivity of p16INK4a/Ki-67 double immunostaining and high risk HPV was 86.7% and 100.0%, and the specificity was 67.8% and 20.7%, respectively. For patients younger and older than 30 years, specificity of p16INK4a/Ki-67 double immunostaining was both higher than that of high risk HPV (80.8% vs. 42.3%; 84.6% vs. 56.9%).@*Conclusions@#p16INK4a/Ki-67 double immunostaining can effectively identify the high risk population in ASCUS or LSIL, with higher specificity than high risk HPV test. p16INK4a/Ki-67 double immunostaining may benefit patients younger than 30 years of age as a preliminary or potential cytology-combining screening tool.
