    Abstract:
    Existing data on the genotype distribution of human papillomavirus (HPV) are limited in Hunan province, central south China. To evaluate the prevalence of HPV infection and its genotype among women with invasive cervical cancer in Hunan, a total of 1,336 patients were included in this study between July 2012 and June 2013. Eighteen high-risk and eight low-risk genotypes of HPV were detected by Luminex xMAP technology. The results show that HPV prevalence in invasive cervical cancer in Hunan was 75.7%. A single HPV infection was found in 82.3% of the HPV-positive samples, and 91.8% of the cases had high-risk HPV infection. The most common HPV type was HPV 16 (50.6%), followed by HPV 58 (12.4%), HPV 52 (10.9%), HPV 18 (7.3%), HPV 33 (5.5%), HPV 59 (4.2%), HPV 39 (4.0%), HPV 61 (3.4%), HPV 31 (3.3%), and HPV 56 (3.2%). A single infection with HPV 16 was detected in 42.5% of the samples, which was significantly more frequent than any other HPV type in this population. Dual-infection with HPV 16 and HPV 52 were relatively common. The available vaccines for HPV 16 and 18 are therefore expected to have a substantial impact on reducing the burden of cervical cancer in China, even though HPV 18 showed a lower frequency. In addition to HPV 16 and 18, other HPV types including 58, 52, and 33, should be targeted in the next generation HPV vaccines.
