BACKGROUND The role of testing for high‐risk human papillomavirus (HR HPV) when triaging women with a cytologic diagnosis of low‐grade squamous intraepithelial lesion (LSIL) has not been well established. The objective of the current study was to correlate the status of HR HPV with the incidence of cervical intraepithelial neoplasia 2 and more severe lesions (CIN 2+) on tissue follow‐up in women with LSIL. METHODS A total of 1046 women with LSIL and HR HPV testing were identified in the database of a large teaching hospital within a 12‐month period. HR HPV testing was performed using the Hybrid Capture 2 assay with 1 relative light unit/cutoff as the cutoff. RESULTS Of the 1046 women with LSIL and concurrent HR HPV testing, 82.3% tested positive for HR HPV, 91.1% of whom were women aged < 30 years and 73% of whom were women aged ≥ 30 years ( P < .001). Cytologic and/or histologic follow‐up was available in 979 (93.6%) women; 25.5% had negative follow‐up, 62.5% were found to have CIN 1 lesions, and 12.0% had CIN 2+ lesions. The sensitivity and negative predictive value of HR HPV status as a marker of CIN 2+ lesions were 98.3% and 98.9%, respectively. The colposcopy rate was 73.3% and 96.9% for women aged ≥ 30 years and women aged < 30 years, respectively ( P = .01). CONCLUSIONS Using 1 RLU/CO as the cutoff value, HR HPV testing was found to be highly sensitive for detecting CIN 2+ lesions in women with LSIL. The colposcopy rate was significantly lower in women aged ≥ 30 years compared with women aged < 30 years. Triaging with HR HPV testing may be indicated in women aged ≥ 30 years with LSIL cytology, but not in women aged < 30 years. Cancer (Cancer Cytopathol) 2011;. © 2011 American Cancer Society.
