Impact of HPV Integration on the Prognosis of Women With Persistent HR-HPV Infection：a Multi-center Cohort Study in China
Clinically, patients with persistent HR-HPV infection for more than 18 months or HR-HPV infection with CIN2 + need regular colposcopic biopsy to assess the outcome and progression of the disease. A total of 1000 participants with persistent HR-HPV infection (100 cases/center) were recruited from multiple centers, and HPV integration status and vaginal flora diversity were sequenced at baseline, 6th month, 12th month and 24th month, respectively, through prospective cohort studies. And to evaluate the influence of HPV integration status and flora changes on the prognosis of women with persistent HR-HPV infection.
