Abstract:
Objective:To investigate the infection status and the infection rate of age stratification of human papillomavirus (HPV) subtypes in women at some areas of Beijing, who were diagnosed with no intraepithelial lesions and canceration, low grade squamous intraepithelial lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL), based on the diagnosis of women′s thinprep cytologic test(TCT).Methods:From January 2019 to December 2019, the cervical exfoliated cells of women who presented in Department of Gynaecology and Obstetrics of Beijing Anzhen Hospital Affiliated to Capital Medical University were collected, and the high-risk HPV typing nucleic acid test kit (fluorescence quantitative PCR) was used for genotyping.The results were retrospectively analyzed.Meanwhile, the patients who were tested by TCT at the same time were screened.According to the TCT pathological diagnosis, these patients were divided into three groups: no intraepithelial lesions and canceration (hereinafter referred to as the control group), low-grade squamous intraepithelial lesions (TCT-LSIL) and high-grade squamous intraepithelial lesions (TCT-HSIL). The chi square test was used for the statistical analysis.Results:In control group (561 cases), 68 cases were infected by at least one subtype of HPV, with a total positive rate of 12.12%.In TCT-LSIL group (385 cases), 288 cases were infected by at least one subtype of HPV, with a total positive rate of 74.81%.In TCT-HSIL group (170 cases), 128 cases were infected by at least one subtype of HPV, with a total positive rate of 75.29%.The highest positive rate was type 52 in the control group, while the highest positive rate was type 16 in the TCT-LSIL and TCT-HSIL groups.The infection rate of the three groups increased with the increase of cervical pathological grade.The infection rates of type 16, 18, 31, 33, 39, 45, 51, 52, 56, 58 and 68 were significantly different among the three groups (all P<0.05). The infection rate of HPV16 in the TCT-HSIL group was significantly higher than that in the control group and the TCT-LSIL group(P′<0.017). After all the subjects were stratified by age, only type 16 had statistical difference in infection rate among different age groups (all P<0.05). After age stratification of three groups, within the age<31 years old, the infection rates of 16, 18, 31, 33, 39, 45, 51, 52, 56 and 58 types were statistically different among the three groups (all P<0.05). In the age range of ≥31-<41 years old, the infection rates of 16, 18, 39, 51, 52, 56 and 58 types were statistically different among the three groups (all P<0.05). In the age range of ≥41-<51 years old, the infection rates of 16, 18, 35, 52, 56 and 58 types were statistically different among the three groups (all P<0.05). In the age≥51 years old, the infection rates of 16, 18, 31, 33, 51, 52 and 58 types were statistically different among the three groups (all P<0.05). After the age stratification of TCT-LSIL group, the infection rates of 16 and 45 types were statistically different among in the four groups of<31, ≥31-<41, ≥41-<51 and ≥51 years old (all P<0.05). However, there was no significant difference in the infection rate of each subtype in the control group and the TCT-HSIL group(all P>0.05). Conclusion:HPV subtypes 16, 18, 51, 52, and 58 are the main infection types in high grade squamous intraepithelial lesion patients, which are the main types of HPV caused cervical lesions.In addition, the infection rates of HPV in patients with cervical high-grade squamous intraepithelial lesionsare similar in different age groups.
