Objective:
The aim of this study was to determine the human papillomavirus (HPV) genotype distribution and to investigate the relationship between HPV genotypes and cervical cytology in women with HPV infection.
Methods:
In this study, 493 women who were admitted to the obstetrics clinic between 2007 and 2015 years and had HPV positivity were examined retrospectively.
Results:
The median age of women included in the study was 37.3 ±10.6. The positivity of single and multiple HPV genotypes was 64.1% and 35.9%, respectively. HPV16 was the most common genotype in women with normal and abnormal cytology. The incidence of atypical squamous cells of undetermined significance (chi-square:8.32 p=0.04) and high-grade squamous intraepithelial lesion (chi-square:13.75 p<0.001) with HPV16 was significantly higher than in other HPV genotypes. In additional, abnormal cytology results in the group 1 (includ-ed HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59) and group 4 (included HPV40, 42, 54, 55, 61, 62, 81, 83, 84) were significantly higher than other groups (chi-square:23.15 p<0.001).
Conclusions:
Group 1 genotype ratios were found to be quite high among women with abnormal cytology and women with normal cytology. For this reason, close follow-up is very important in addition to cytological findings along with genotyping, especially from an early age. We were found that multiple HPV infection was not related to the grades of cytological abnormalities. Although abnormal cytology results in group 4 were significantly higher than the other groups, it was not possible to comment on the relationship between these genotypes and cervical cancer since more than one HPV genotype was found in most of these women.
