Management of atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesions of the uterine cervix with human papilloma virus infection among young women aged less than 25 years.

Current ASCCP guidelines recommend repeat cytology 12 months after HPV-positive results in women aged 21-24 years with either atypical squamous cells of undetermined significance (ASCUS) or a low-grade squamous intraepithelial lesion (LSIL). The purpose of this study was to validate an algorithm in such women with ASCUS or LSIL. A multicenter cross-sectional study was carried out at three academic hospitals involving 40,847 Korean women who underwent cervical cancer screening with cytology and HPV testing with or without subsequent colposcopic biopsies between January 2007 and December 2013. Among a total of 3,193 women with available histopathology data, 762 women with ASCUS and 758 with LSIL were HPV-positive. Among HPV-positive women with ASCUS, 38.5% of women aged 21-24 years had ≥CIN2, compared to 20.8% of women aged 30-65 years and 21.1% of the total women. Among HPV-positive women with LSIL, 25.8% aged 21-24 years had ≥CIN2, compared to 21.2% of women aged 30-65 years and 21.9% of the total women. In HPV-positive women with ASCUS/LSIL aged less than 25 years, the prevalence of ≥CIN2 lesions was 34.5%, which was significantly higher than that (21.0%) in women aged ≥25 years. The risk of ≥CIN2 lesions in HPV-positive Korean women aged 21-24 years with ASCUS or LSIL was not lower than that in older women. Colposcopic examination should be considered for management of HPV-positive young women with ASCUS or LSIL. Diagn. Cytopathol. 2016;44:959-963. © 2016 Wiley Periodicals, Inc.

Punch biopsy guided by both colposcopy and HR-HPV status is more efficient for identification of immediate high-grade squamous intraepithelial lesion or worse among HPV-infected women with atypical squamous cells of undetermined significance.

To investigate the accuracy of colposcopy for diagnosing high-grade squamous intraepithelial lesion (HSIL) or worse (HSIL+) in human papillomavirus (HPV)-infected patients with atypical squamous cells of undetermined significance (ASCUS) cytology, and determine whether genotyping and viral load quantitation can be useful for detecting immediate HSIL+ risk in these patients. This study included 620 cases with ASCUS and positive for high-risk (HR)-HPV within 1 month before or after cervical cytology at Qilu Hospital between February 2013 and February 2014. Based on the colposcopic impression, lesion-targeted punch biopsy, endocervical curettage biopsy or random cervical punch biopsy in four quadrants was performed on these patients within 1 month. The accuracy of colposcopy for diagnosing HSIL+ was evaluated through comparison with the biopsy results. HR-HPV status determined by Hybrid Capture 2 or HPV genotyping was analysed retrospectively as a possible predictor of HSIL+. Agreement between colposcopic impression and cervical pathology was matched perfectly in 89.2% of cases (553/620), and the strength of agreement with the κ statistic was 0.698 (p<0.001). Colposcopy had high specificity (96.9%) but low sensitivity for detecting HSIL+ (67.5%). The risk of HSIL+ was significantly higher in patients with HPV-16 infection (52.3%) than in patients infected with other types of HPV (17.9%, p<0.001). HSIL+ and virus load was correlated at cut-offs (CO) of 50 relative light units (RLU)/CO and 100 RLU/CO (p=0.024 and 0.044, respectively). If considering HPV16 infection or high virus load (at 50 RLU/CO) as a diagnostic standard of HSIL+ when colposcopic impression was negative, sensitivity was improved to 74.7% and 81.0%, respectively. Good agreement was found between colposcopic and pathologic diagnosis. HR-HPV genotyping or virus load is relevant to the detection of HSIL+ among HPV-infected patients with ASCUS cytology. In these patients, biopsies considering HPV-16 infection or virus load ≥50 RLU/CO may be helpful for increasing the HSIL+ detection rate.

Introduction of liquid-based cytology and human papillomavirus testing in cervical cancer screening in Luxembourg.

In 2014, liquid-based cytology with HPV triage replaced conventional cytology. The aim of our study was to compare conventional and liquid-based cytology (LBC), estimate the prevalence of abnormal cervical cytology and high risk HPV (hrHPV) infection and their correlation, among screened women in Luxembourg. Between the first January 2013 and 31st December 2015, 315,868 cervical samples from 150,815 women (mean age 42.2 years) were investigated by the national cytology laboratory. Slides were prepared and screened according to European Guidelines. All cytological results were classified according to the Bethesda 2001 system terminology. The prevalence of abnormal cervical lesions was as follows: atypical squamous cells of undetermined significance (ASC-US), 1.3%; low-grade squamous intraepithelial lesion (LSIL), 1.9%; high-grade squamous intraepithelial lesion (HSIL), 0.4%. The detection rate of cytological lesions was significantly higher with LBC than with conventional cytology. Based on 11,838 samples with concomitant cytology and HPV testing, hrHPV was detected in 9.5, 45.3, 70.0, and 92.6% of women with negative cytology, ASC-US, LSIL, and HSIL, respectively. More cervical lesions were identified using LBC compared to conventional cytology. HrHPV infection was correlated with the severity of intraepithelial lesions. The current findings provide important information to evaluate the prevention of cervical cancer in Luxembourg and for monitoring the future impact of HPV vaccination. Diagn.
