Human papillomavirus genotype-specific risk in cervical carcinogenesis

초록

Objective: To evaluate the risk of genotype-specific human papillomavirus (HPV) infections for the spectrum of cervical carcinogenesis and the distribution of HPV types according to age and different cervical lesions Methods: This study included HPV-positive women who underwent cervical biopsy at the Cheil General Hospital & Women's Healthcare Center between July 1, 2011 and December 31, 2017. HPV genotyping was conducted using a Cheil HPV DNA chip kit. Results: The study sample consisted of 400 normal, 399 cervical intraepithelial neoplasia (CIN) 1, 400 CIN 2, 400 CIN 3, and 389 cervical cancer cases. HPV 16 was the most common type found with a prevalence of 9.5% in normal, 6.8% in CIN 1, 15.0% in CIN 2, 44.5% in CIN 3, and 64.3% in cervical cancer. The most common HPV types were 16, 52, 58, 53, 51, 56, 68, and 18 in all study samples. HPV 16, 31, 33, and 58 were more common in CIN 2/3 and cancer, and HPV 39, 51, 53, 56, 66, and 68 were more common in CIN 1 and normal cases (p<0.001). In CIN 3 and cervical cancer, HPV 16 was the most common type in all age groups. HPV 52 was the most common type in CIN 2 (all age groups) and in CIN 1/normal (age <= 30 years) cases. Among the high-risk HPV types, 16, 31, 33, 52, and 58 showed significant risk for high-grade disease. Conclusions: HPV 16, 31, 33, 52, and 58 showed the significant risk of high-grade disease for cervical carcinogenesis.
