Abstract

Background

Studies on the clinical performance of p16/Ki-67 dual-staining in detecting cervical lesions by menopausal status were limited.

Methods

4364 eligible women were enrolled with valid p16/Ki-67, HR-HPV, and LBC test results, including 542 cancer and 217 CIN2/3 cases. The positivity rates of p16 and Ki-67 single staining and p16/ Ki-67 dual-staining were analyzed by different pathological grades and age groups. The sensitivity (SEN), specificity (SPE), positive predictive value (PPV), and negative predictive value (NPV) of each test in different subgroups were calculated and compared.

Results

P16/Ki-67 dual-staining positivity increased with histopathological severity in premenopausal and postmenopausal women (P < 0.05), while no increasing trends of individual expression of p16 single staining and Ki-67 single staining were observed in postmenopausal women. P16/Ki-67 showed higher SPE (88.09% vs. 81.91%, P < 0.001) and PPV (33.8% vs. 13.18%, P < 0.001) in detecting CIN2/3, and higher SEN (89.97% vs. 82.61%, P = 0.012) and SPE (83.22% vs. 79.89%, P = 0.011) in detecting cancer in premenopausal women than postmenopausal women. For triaging the HR-HPV+ population to identify CIN2/3, p16/Ki-67 performed comparably to LBC in the premenopausal women, and showed higher PPV (51.14% vs. 23.08%, P < 0.001) in premenopausal than postmenopausal women. For triaging ASC-US/LSIL population, p16/Ki-67 demonstrated higher SPE and lower colposcopy referral rate than HR-HPV in both premenopausal and postmenopausal women.

Conclusions

Expressions of p16/Ki-67 dual-staining between premenopausal and postmenopausal women are varied. P16/Ki-67 performs better in detecting cervical lesions in premenopausal women. For triaging, p16/Ki-67 is suitable for HR-HPV+ women, especially premenopausal women, to identify CIN2/3 and women with ASC-US/LSIL.
