Association between high-risk human papillomavirus DNA load detected by hybrid capture II and high-grade precursor lesions of cervical cancer in women

INTRODUCTION: Infection with oncogenic human papilloma virus (HPV) has been established as the main etiologic agent for cervical cancer and of cervical intraepithelial neoplasia (CIN). OBJECTIVE: To determine the association between viral loads of the high risk HPV using the hybrid capture II (HC II) system and CIN lesion stage. MATERIAL AND METHOD: A total of 982 women with diagnosis of negative or of CIN I-III with Pap or liquid-based cytology (DNA-Citoliq-Digene) were included. HC II testing was used to detected HPV DNA. Viral load was measured expressed as relative lights unit (RLU) ratio. RLU ratios were categorized for analysis into three groups: negative (< 1 pg/ml); positive with low viral load (< 100 pg/ml); positive with high viral load (> 100 pg/ml). RESULTS: A total of 152 (72.4%) of 210 (21.4%) patients with CIN II, 53 (61.6%) of 86 (43.6%) with CIN II-III were positive for HPV DNA, the higher the viral load (> 100 pg/ml) were observed in 101 (66.4%) and 53 (61.6%) patients with CIN I or CIN II-III, respectively. DISCUSSION AND CONCLUSIONS: Our results suggest a clear association between viral load HPV DNA determined by HC II (version 1) assay and CIN stage. We concluded that the high viral load has a clinical importance for the management of patients with CIN.
