Multivariate analysis revealed that only age ≥35 years (P=0.033), major abnormal cytology (P=0.002), and pre-cone high-risk human papillomavirus load ≥300 relative light units (P=0.011) were significant factors associated with residual disease.Conclusion: Age ≥35 years, major abnormal cytology, and pre-cone high-risk human papillomavirus load ≥300 relative light units were the only significant factors predicting post-cone residual disease. Appropriate application of these predictive factors may avoid delayed treatment and overtreatment.
