Abstract:
Objective To investigate the prevalence and genotype distribution of human papilloma virus (HPV) infection among patients with cervical carcinoma or precancerous lesions in Xuzhou region. Methods 688 patients with cervical lesions confirmed by colposcopic biopsy were assigned to three groups:low-grade squamous intraepithelial lesion (LSIL) (187 cases), high-grade squamous intraepithelial lesion (HSIL) (359 cases) and cervical carcinoma (142 cases). The genotypes of HPV were determined by nucleic acid hybridization technique. The prevalence and genotype distribution of HPV were further analyzed. Results The infection rates of HPV in LSIL , HSIL and ICC group were 68.98 % (129/187), 94.99 % (341/359), 95.78 % (136/142), respectively. These rates were statistically significant different (P< 0.05). With the aggravation of cervical lesions, HR-HPV infection rate was gradually increased and LR-HPV infection rate was gradually decreased. The most common HPV types were listed below in order of decreasing prevalence. LSIL:HPV16, 52, 58, 18, 31; HSIL: HPV16, 58, 33, 31, 52; cervical carcinoma: HPV16, 31, 58, 18, 33. Based on the cumulative logistic regression model, confidence intervals of the relevance between the overall HPV prevalence and occurrence of cervical lesions were calculated: HPV16 (OR= 7.215, P< 0.05), HPV31 (OR=2.768, P<0.05), HPV33 (OR=1.846, P<0.05), HPV58 (OR=1.726, P<0.05) Conclusions The prevalence of HR-HPV infections increased with the aggravation of cervical carcinoma in Xuzhou region. In order of decreasing prevalence, the most prevalent of HPV types are HPV16, 31, 33, 58. The results indicate that HPV18 have strong tumorigenicity, but is not popular in Xuzhou region. By contrast HPV52 is more common in LSIL than that in cervical carcinoma.
