Risk assessment of cervical disease by hrHPV testing and cytology

As cervical cancer is an important health problem worldwide with over a half million patients a year and as it is the fourth most common cause of cancer-related death in women, improving the prevention of this disease is a continuing and important process. A major reduction of cancer incidence and mortality has occurred in countries with cervical cancer screening. Because cervical cancer develops through different premalignant stages it can be detected in a premalignant stage, allowing treatment before these stages would be able to develop into cervical cancer.

Long-term CIN3 risk in women with abnormal cytology; Role of hrHPV testing

Background: Many studies have examined the short-term value of high-risk human papillomavirus (hrHPV) testing in predicting cumulative risk of cervical intraepithelial neoplasia grade 3 or cancer (CIN3). This study focuses on long-term CIN3 risk after initial wait and see policy. Methods: A total of 342 women with abnormal cytology of borderline/mild dyskaryosis (BMD) or worse (>BMD), included between 1990 and 1992, were followed-up by cytology and hrHPV testing until 1996 and monitored by cytology thereafter. Primary endpoint was cumulative CIN3 risk by December 2009.Results:Women with BMD had a 5-year CIN3 risk of 22.5% (95% confidence interval (CI) 17.0-29.1) and of 0.7% (0.1-4.5) in the subsequent 5 years. High-risk human papillomavirus-negative women with BMD had a 5-year risk of <0.01% (95% CI <0.0-5.1) and of 0.01% (0.0-5.7) in the following 5 years, while for hrHPV-positive women these risks were 37.5% (29.0-46.9) and 1.6% (0.2-9.5), respectively. Women with BMD< had a 5-year risk of 45.1% (36.4-54.1) and of 3.5% (0.9-12.2) in the subsequent 5 years. High-risk human papillomavirus-negative women with < BMD had a 5-year risk of 7.3% (2.0-23.6) and hrHPV-positive women of 56.6% (46.4-66.3). Conclusion: Women with BMD have an elevated CIN3 risk for 5 years only; afterwards their risk is similar to the general population. High-risk human papillomavirus-negative women with BMD may return to regular screening directly. All other women with ≥ BMD should be referred for additional testing and/or colposcopy

Agreement between colposcopic impression and histological diagnosis among human papillomavirus type 16-positive women: A clinical trial using dynamic spectral imaging colposcopy

Summarization: To investigate the agreement between conventional colposcopic impression, dynamic spectral imaging (DSI) colposcopy and histology, for human papillomavirus type 16-positive (HPV16(+)) and non-16 high-risk (hr) HPV(+) women. Prospective, comparative, multicentre clinical trial. Three colposcopy clinics in the Netherlands. Women (n = 177) aged 18 years or over with an intact cervix, referred for colposcopy. The colposcopist graded the lesion by using the DSI colposcope as a regular video colposcope. Subsequently the DSI impression was displayed and biopsies were taken from all abnormal areas as well as from a random (normal) site. A cervical smear was taken for HPV typing. Histologically confirmed high-grade cervical intraepithelial neoplasia or cancer (CIN2(+)), positive for HPV16 or for any other hrHPV type. The DSI colposcope identified more CIN2(+) cervical lesions among HPV16(+) women than in non-16 hrHPV(+) women (P = 0.032 regardless of final histology and P = 0.009 among women with CIN2(+)). Consequently, the sensitivity of the DSI colposcope for detecting CIN2(+) lesions was higher in HPV16(+) women than in non-16 hrHPV(+) women (97% versus 74%, P = 0.009). No such differences were seen for the colposcopist impression. In addition, mainly smaller cervical lesions are missed by the colposcopist. The sensitivity of DSI colposcopy for CIN2(+) is higher in HPV16(+) than in non-16 hrHPV(+) women. Furthermore, regardless of HPV16 status, the sensitivity of DSI for CIN2(+) is higher than that of the colposcopist, probably because colposcopists tend to miss smaller cervical lesions.Presented on: BJOG: An International Journal of Obstetrics and Gynaecolog
