HR-HPV viral load quality detection provide more accurate prediction for residual lesions after treatment: a prospective cohort study in patients with high-grade squamous lesions or worse

This study aimed to evaluate the clinical value of HR-HPV viral loads to predict the residual/recurrence lesions among women with high-grade squamous lesions or worse ( ≥ HSIL) after surgery. Finally, 301 women who underwent primary screening of cervical cancer using polymerase-chain-reaction-(PCR)-reverse-dot-blot-(RDB) human papillomavirus (HPV) genotyping and cytology assays were enrolled. They received surgery and took HR-HPV viral loads with a BioPerfectus Multiplex Real-Time PCR assay. Colposcopy biopsies were performed in patients with HPV-16/18(+) and/or TCT ≥ ASCUS with HR-HPV(+). The risk of HR-HPV viral loads and potentials factors for residual/recurrence lesions were analyzed and the optimal cut-off values of HR-HPV viral loads were calc ulated. The significant differences were found in residual/recurrence lesions among patients with different ages, margin status, cytology and HR-HPV at 6 months (allP <  0.05). Interestingly, HPV viral loads were observed significant differences in the group of residual lesions, not recurrence group. Furthermore, except for HPV-31/33, the viral loads of HP-16/52/58 were significant differences in residual lesions. The cut-off level of HR-HPV viral loads was 5.22 copies/10,000 cells, providing viable triage for the risk of residual lesions. Compared with different follow-up methods, the HR-HPV viral loads ≥ 5.22copies/10,000 cells (HR 3.39, 95% CI 1.57–7.35) had a higher risk for developing residual lesion...
