    Abstract:
    OBJECTIVE: To study the prevalence and genotype distribution of human papillomavirus (HPV) among women with cervical cancer or high-grade squamous intraepithelial lesions (HSIL) in western China. METHODS: Cervical cast-off cells from 144 women with cervical cancer and 63 women with HSIL were tested for HPV genotypes using an oligonucleotide microarray. RESULTS: The overall HPV prevalence was 80.6% in cases of carcinoma and 61.9% in cases of HSIL. The most common genotypes were HPV-16 (carcinoma, 68.1%; HSIL, 34.9%) and HPV-58 (carcinoma, 8.3%; HSIL, 17.5%). Other high-risk types included HPV-18, -31, -33, -35, -45, and -52, with HPV-18 more common in adenocarcinomas than in squamous cell carcinomas (21.4% vs 3.1%; P<0.02). The HPV prevalence was lower among patients older than 49 years (P<0.02). CONCLUSION: The prevalence of HPV-16 and HPV-58 was high. This finding may help to improve HPV vaccination and cervical cancer prevention programs in western China.
