This study aimed to evaluate the correlation between HPV viral load and PAX1 methylation and their effectiveness in predicting cervical lesions. The results showed that hypermethylation of PAX1 was associated with high HPV viral load, especially HPV16/18. PAX1 methylation had the highest specificity in diagnosing CIN2+, followed by HPV16/18 viral load, both of which were higher than cytology >= ASCUS.
Background: PAX1 methylation (PAX1(m)) and HPV viral load (VL) have been reported to detect cervical high-grade squamous intraepithelial lesions (HSIL), but the relationship between them is unclear. This study aimed to evaluate the correlation between HPV VL and PAX1(m) and its effectiveness in predicting cervical lesions. (2) Methods: A total of 476 women referred to colposcopy for abnormal cervical screening at the Peking University People's Hospital between November 2020 and November 2021 were enrolled. PAX1(m) and HPV VL were determined by QMSP and BMRT-HPV reports type-specific VL/10,000 cells, respectively. (3) Results: PAX1(m) was significantly increased in HSIL, especially in cervical cancer, but there was no significant difference between cervical intraepithelial neoplasms 1(CIN1) and CIN2. However, HPV VL significantly differed between CIN1 and CIN2 but not between CIN3 and cervical cancer. In general, PAX1(m) positively correlated with all hrHPV VL, mainly in the HPV16/18 VL (p < 0.001), but had no relationship with the other 12 types of hrHPV VL. PAX1(m) had the highest specificity in diagnosing CIN2+, followed by HPV16/18 VL, which are higher than cytology >= ASCUS. (4) Conclusions: Hypermethylation of PAX1 is associated with high HPV VL, especially HPV16/18, and both present advantageous specificity in detecting CIN2+.
