Relationship between cervical lesions and human papillomavirus genotype infection among the women in Northeast region of Sichuan province / 重庆医学

ABSTRACT

Objective To investigate the relationship between different genotype infection and multiple infection of human papil‐lomavirus(HPV) with cervical lesions among the women in Northeast region of Sichuan province .Methods The cervical exfoliated cells in 213 women with HPV infection were performed the HPV genetype detection by the gene chip technique and the cervical le‐sion degree was also detected .Results 213 cases of cervial lesion with positive HPV infection were divided into five groups accord‐ing to pathological examination results:chronic inflammation(110 cases) ,cervical intraepithelial neoplasia(CIN) Ⅰ (21 cases) ,CINⅡ (26 cases ) ,CIN Ⅲ (28 cases ) and cervical cancer (28 cases) .The high risk HPV infection was dominated by the genotype HPV16 ,58 ,33 ,18 and the low risk HPV infection was dominated by the HPV genotype 11 ,6 .The HPV genotype HPV11/6/16 , HPV16/33 ,HPV16/6 ,HPV16/58 and HPV16/18 infection were most common in the chronic cervial inflammation ,CIN Ⅰ ,CINⅡ ,CIN Ⅲ and cervical cancer groups .The constituent ratio of different cervical lesions had statistical difference between the simple high risk HPV infection group and the low risk HPV infection group (χ2 = 41 .01 ,P 0 .05) .Conclusion HPV 16 ,58 ,33 ,18 are the main high risk HPV genotypes among women in the northeast region of Sichuan province ,HPV 16 is significantly related with the cervial lesion degree ;multiple HPV genotype infection does not promote the progress of cervical lesion .
