Colposcopic and histopathologic evaluation of women with HPV persistence exiting an organized screening program

Human papillomavirus–based screening has a higher sensitivity for precursors of cervical cancer compared with cytology-based screening. However, more evidence is needed on optimal management of human papillomavirus–positive women. The objective of the study was to compare the risk of histopathologically confirmed cervical intraepithelial lesions grade 2 or worse after 1 and 3 years of human papillomavirus persistence, respectively, and evaluate the clinical management of human papillomavirus–positive women in the 56–60 year age group. This was a randomized health care policy offering human papillomavirus screening to 50% of resident women aged 56–60 years in the Stockholm/Gotland region of Sweden during January 2012 through May 2014. Women who were human papillomavirus positive/cytology negative at baseline were referred for a repeat test after 1 or 3 years. In case of human papillomavirus persistence, women were referred for colposcopy, including biopsies and endocervical sampling. The human papillomavirus prevalence was 5.5% (405 women of 7325 attending). Among the 405 human papillomavirus–positive women, 313 were reflex test cytology negative at baseline and were referred for a repeat human papillomavirus test, 176 women after 1 year and 137 women after 3 years. After 1 year, 91 of 176 (52%) were persistently human papillomavirus positive and after 3 years 55 of 137 (40%) (P = .042). In repeat cytology, 10 of the 91 (12%) were positive after 1 year and 15 of 55 (33%) after 3 years (P = .005). The attendance rates for colposcopy were similar: 82 of 91 (90%) in the 1 year group and 45 of 55 (82%) in the 3 year group. All women attending colposcopy were postmenopausal, and endocervical sampling and punch biopsies were performed to facilitate colposcopic management, with a positive predictive value of 43–50% and 28–31%, respectively. Histopathologically confirmed cervical intraepithelial lesions grade 2 or worse was found in 19 of 82 women (23%) and 9 of 45 women (20%) in the 1 year and 3 year groups, respectively, and registry linkage follow-up found no cancers in either group. Human papillomavirus genotyping was predictive of cervical intraepithelial lesions grade 2 or worse, and human papillomavirus 16 was the most common genotype at human papillomavirus persistence, occurring in 18% of the cases in the 1 year group and 20% in the 3 year group. It was safe to postpone repeat human papillomavirus tests for 3 years in postmenopausal women attending the org
