The changes of HR-HPV infection and cervical lesions detection, a
ten-year retrospective study
Abstract
Objective: To understand the changes of high-risk human papillomaviruses
(HR-HPV) infection and detection of cervical high-grade squamous
intraepithelial lesion or higher (HSIL+) from 2012 to 2021. Design:
Retrospective observational study. Setting: A tertiary hospital in
northwest China. Population: Women aged >25 years who
underwent primary HR-HPV testing and referred for colposcopy biopsy from
January 2012 to December 2021. Methods: The trends of HR-HPV infection
and detection of HSIL+ were described and analyzed. All participants
were divided into four groups with 25-35, 36-45, 46-55, and
>55 years, respectively. Main outcome measures: HR-HPV
infection was screened out by HPV examination. Cervical cancer and HSIL
were confirmed in biopsies. Results: Our data indicated that the HR-HPV
infection rate showed a general decreasing trend (APC = -7.34%, 95%CI:
-11.38% ~ -3.13%) from 2012 to 2021. Population with
the highest infection rate of HR-HPV was over 55 years group. On the
contrary, the detection rates of cervical HSIL+ showed an increasing
trend (APC=15.30%, 95%CI: 9.64% - 21.25% ). However, the detection
rate of cervical cancer showed a downward trend (APC = -12.65%, 95%CI:
-17.68% - -7.32%). Unsurprisingly, the detection rate of cervical
lesions in population over 55 years was the highest among different
groups. The common HR-HPV subtypes were HPV52 (20.96%), HPV16
(16.70%), HPV58 (13.95%), HPV56 (13.04%) and HPV51 (12.31%).
Conclusions: Our data suggested that proactive prevention and screening
measures helped to decrease HR-HPV infection rates and decrease
detection rate of cervical cancer past ten years and should be further
advocated in other areas.
