TL;DR: A consistently low six year cumulative incidence rate of CIN3+ among women negative for HPV suggests that cervical screening strategies in which women are screened for HPV every six years are safe and effective.
Abstract: OBJECTIVE: To obtain large scale and generalisable data on the long term predictive value of cytology and human papillomavirus (HPV) testing for development of cervical intraepithelial neoplasia grade 3 or cancer (CIN3+). DESIGN: Multinational cohort study with joint database analysis. SETTING: Seven primary HPV screening studies in six European countries. PARTICIPANTS: 24,295 women attending cervical screening enrolled into HPV screening trials who had at least one cervical cytology or histopathology examination during follow-up. MAIN OUTCOME MEASURE: Long term cumulative incidence of CIN3+. RESULTS: The cumulative incidence rate of CIN3+ after six years was considerably lower among women negative for HPV at baseline (0.27%, 95% confidence interval 0.12% to 0.45%) than among women with negative results on cytology (0.97%, 0.53% to 1.34%)). By comparison, the cumulative incidence rate for women with negative cytology results at the most commonly recommended screening interval in Europe (three years) was 0.51% (0.23% to 0.77%). The cumulative incidence rate among women with negative cytology results who were positive for HPV increased continuously over time, reaching 10% at six years, whereas the rate among women with positive cytology results who were negative for HPV remained below 3%. CONCLUSIONS: A consistently low six year cumulative incidence rate of CIN3+ among women negative for HPV suggests that cervical screening strategies in which women are screened for HPV every six years are safe and effective.

TL;DR: Comparison of the detection rate and positive predictive values of HPV assay with cytology and the best management strategy for HPV-positive women found HPV testing was more sensitive than borderline or worse cytology but less specific for detecting CIN2+.

TL;DR: Sufficient evidence exists to recommend HPV testing in triage of women with atypical cytology and in surveillance after treatment of CIN lesions, and the European screening policy will be reviewed based on the longitudinal results of randomised population trials which are currently underway.

TL;DR: Using the conventional impression cytology technique for conjunctival study by designing a 24-well Teflon sample holder, using cellulose acetate paper cut in an asymmetrical shape, and introducing Gill's modified Papanicolaou stain, this modified technique may help increase understanding of various ocular surface disorders.
