Abstract/OtherAbstract:
Population-specific epidemiological data on human papillomavirus (HPV) infection are essential for formulating strategies to prevent cervical cancer. The age-specific prevalence of HPV infection was determined among 1,600 women enrolled for cervical screening in Macao. A U-shaped age-specific prevalence curve with a first peak (prevalence rate, 10%) at 20-25 years and a second peak (13%) at 51-55 years was observed. Co-infections with multiple types were detected in 32.5% of HPV-positive subjects and without significant variation among different age groups (P = 0.318). The majority (84.6%) of the positive samples harbored high- or probable high-risk HPV types, and these types also exhibited a similar U-shaped age-specific prevalence curve. In contrast, low and unknown-risk HPV types remained at a low prevalence (1.5-2.5%) throughout the age groups between 20 and 50 years, and with a small peak (4.5%) at 51-55 years. HPV 52 was the most common type found in 26.8% of positive samples, followed by HPV 16 (15.5%), HPV 68 (11.4%), HPV 18 and HPV 58 (8.9% each), HPV 54 (8.1%), HPV 53 (7.3%), HPV 39 (6.5%), HPV 33 and HPV 66 (5.7% each). In conclusion, because of the early peak of infection, vaccination and educational campaigns in Macao should start early and target at teenagers. The presence of a second peak containing mainly high-risk HPV types in older women indicates the need to evaluate the cover of the cervical screening programme for older women. Further study to determine the contribution of HPV 52 in high-grade cervical neoplasia and invasive cancers in Macao is warranted.
