Spectrum of HPV types before and after treatment of cervical intraepithelial neoplasia grade 2 and 3

About one out six treated women (16%) manifested at least one persistent HR HPV type, that was associated with recurrent or residual HSIL disease (odds ratio 58.1, 95% CI 7.4-457) (p = 0.0001). Testing for HR HPV demonstrated high sensitivity (92%) for residual HSIL. The higher persistency rate of LR HPV types suggests that they are more likely to be outside the treated area.
