Detection of p16/Ki-67 in women with abnormal cytological results and its diagnostic value for cervical intraepithelial neoplasia II+ grade / 国际生物医学工程杂志

ABSTRACT

Objective:To explore the detection capability of p16/Ki-67 double staining technique in women with various abnormal thinprep cytologic test (TCT) results and its diagnostic value for cervical intraepithelial neoplasia Ⅱ+ grade (CIN2+).Methods:A total of 225 women with abnormal TCT results, i.e. the atypical squamous cells of undetermined significance(ASC-US), in the Tianjin Central Hospital of Gynecology Obstetrics, Nankai University Affiliated Maternity Hospital from December 2018 to December 2019 were enrolled. p16/Ki-67 double staining were detected and compared with the high risk human papillomavirus (HR-HPV) and pathological results.Results:The positive rates of p16/Ki-67 double staining increased with cytologic and pathologic categories. For diagnosis of CIN2+, p16/Ki-67double staining (90.1%) was less sensitive than HR-HPV testing (98.2%)( P<0.05), but the specificity of p16/Ki-67 double staining (58.8%) was significantly higher than HR-HPV(21.6%) ( P<0.001). Conclusions:Compared with HR-HPV, p16/Ki-67 double staining has better effect on diagnosing CIN2+. p16/Ki-67 double staining can be considered as triaging method for management of ASC-US and LSIL patients, significantly reduce the colposcopy referral rate (nearly 50%), which has high clinical application value.
