OBJECTIVE:
To determinate the frequency of high risk human papillomavirus (HR-HPV) by hybrid capture II (r) (CH II(r)), according cytology results in women treated for squamous intraepithelial lesions of the cervix (SIL).
MATERIAL AND METHODS:
A descriptive cross-sectional study of a series of cases that included 122 women treated, 79 (75%) for low grade SIL (LSIL) and 43 (35%) for high grade SIL (HSIL) attending at the HPV Laboratory at the Health Sciences Research Institute (IICS), National University of Asunción (UNA), for post-treatment control during period 2006/2010.
RESULTS:
A total of 28% (34/122) of women treated for SIL were positive for HR-HPV, detecting viral infection in 20% of women with no SIL (NSIL) (22/108), in 83% of women with LSIL (10/12) and in 100% of women with HSIL (2/2). Of 34 women positive for HR-HPV, 10 women (29%) had high values (100 pg / mL or more) of relative viral load, detecting an increase of positive cases with severity of the lesion (28% NSIL, 30% LSIL, 50% HSIL).
CONCLUSION:
HR-HPV detection by CH II(r) and high relative viral load values especially in women with NSIL could help to identify treated women at risk of developing recurrence, thereby contributing to strengthening the cervical cancer prevention program.
