Abstract

Background: Cervical cancer is a cancer with a high incidence and death rate. The reason is known by HPV infection. Most women infected with HPV will clear themselves from the body. About 5-10% of new high-risk HPV infections develop into cervical cancer. Objectives: The study was designed to determine DNA-HPV transition rates and related factors to DNA-HPV transition in HPV-infected women of 18–69 years of age in Can Tho City from 2013 to 2019. Materials and methods: Both a retrospective and a prospective cohort study were employed to complete the study. Interviews, gynecological examinations and HPV testing 225 women 18-69 years in can tho city, who were used to collect data for the study. The results were recorded and compared with those of HPV in 2013 to assess the development of HPV over time: transition included conversion to HPV positive state when the results changed from negative (2013) to positive (2019). No transition included clearance of HPV when the positive (2013) results turned negative (2019) or the results remained negative or positive after two phases of testing. At the same time, the factors related to the change were analyzed. Results: There were 16% of cases of DNA-HPV conversion to HPV positive state while 66.6% of cases of DNA-HPV clearance of HPV were witnessed; remaining HPV were 67.1%. The following were recognized as factors that are related to the DNA-HPV harmful transition: age (the ≤ 45 age group had 3.3 times higher of transition risk than the > 45 age group (95%CI: 1.1–9.5)); sexual partner change with OR=3.6 (95%CI: 1.1–12.5); sexual partners change from their husbands' side with OR = 3.9 (95%CI: 1.3–11.8); sexually transmitted diseases with OR = 5.0 (95%CI: 1.2–21.2); and gynecological infections with OR = 3.6 (95%CI: 1.2–11.1). Conclusion: 16% of women with DNA-HPV transition developed conversion to HPV positive state, and it was figured out that the changes in sexual habits will increase the risk of this negative transition.
