Prevalence and distribution of human papillomavirus genotypes among women with high‐grade squamous intraepithelial lesion and invasive cervical cancer in Ganzhou, China

摘要

Background Human papillomavirus (HPV) infection can lead to the development of cervical cancer. This study assessed the genotype distribution of HPV of high‐grade squamous intraepithelial lesion (HSIL) and invasive cervical cancer (ICC) in Ganzhou population. Methods A total of 935 females who got HPV testing from January 2016 to July 2018 in the maternal and child health hospital of Ganzhou were enrolled in the study, including 806 HSIL and 129 ICC. HPV detection and genotyping were tested by HPV Geno‐Array test kit. Results The overall HPV‐positive rate was 74.0% in Ganzhou. Among the HSIL and ICC patients, the positive rates of HPV detection were 75.6% and 64.3%. Among the HSIL individuals, the most prevalent hr‐HPV genotype was HPV 16. And the 4 common subtypes in decreasing order were HPV 52, 58, 33, and 18. Of the ICC patients, the most frequently hr‐HPV subtype was HPV 16 followed by 18, 52, 58, and 59. Among the squamous cell carcinoma (SCC) patients, for hr‐HPV genotypes, HPV 16, 18, 52, 58, and 59 were five most common subtypes. In patients with adenocarcinoma (ADC), the most common hr‐HPV genotype was HPV 18, followed by HPV 16, 52, 56, 68, 73. And, we found U‐shaped and S‐shaped curves in the HPV distribution of different age groups. Conclusion The prevalence and distribution of HPV genotypes in Ganzhou differed from other regions of China and Western countries. These results can serve as valuable reference for HPV vaccination programs for Ganzhou women.
