A Distinct Human Papilloma Virus Epidemiological Profile of Korean-Chinese Women Living in Yanbian, China

초록

Cervical cancer is a common in women worldwide. Human papilloma virus (HPV), which is known to be a direct cause of cervical cancer, differs in its infection rate and genotype by country, geography, race, genetic factors, and immune status. No previously reported studies have reported the HPV prevalence and genotype distributions of Korean-Chinese women living in China. This study examined the prevalence and genotype distribution of HPV among Korean-Chinese women to find similarities and differences compared to Han-Chinese women and Korean women. We also evaluated the effectiveness of a genotyping test compared with liquid-based cytology (LBC) as a screening test. We performed LBC and HPV genotyping tests on 2099 women living in the Yanbian region. The mean age of the 2099 subjects was 42.5 years (18-82). The largest ethnic groups were Han-Chinese (78%), Korean-Chinese (20.2%), Man-Chinese (0.8%), Jang-Chinese (0.04%), and Myo-Chinese (0.04%). Of the Korean-Chinese women, 34.4% tested positive for HPV; the most prevalent subtypes were 52, 58, 16, 53, and 33, which was clearly different from those of Han-Chinese women and other Koreans. The results of LBC showed a false negative rate of 62.4% compared with the results of HPV genotyping tests. This shows that a cervical cancer screening system utilizing HPV genotyping or a combined method is more effective. According to the HPV profile, only the Gardasil 9 vaccine can cover the HPV subtypes prevalent in Korean-Chinese women in the Yanbian region. This paper is the first report on HPV epidemiology among Korean-Chinese women in China.
