Clinical Analysis of Human Papillomavirus in Paraffin-embedded Cervical Lesion Tissues by Gene Clip Technology / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the clinical significance of human papillomavirus in paraffin-embedded cervical cancer and precancerous lesion tissue by gene clip technology.METHODS 153 Patients with paraffin-embedded examples.DNA was extracted from paraffin-embedded tissues and amplified by polymerase chain reaction(PCR).RESULTS The positive rate of high-risk HPV of inflammation was 8.33%,CINⅠ45.83%,CINⅡ/CINⅢ 87.50% and invasive cancer 92.21%.The HPV infection rate of squamous cell carcinoma was 94.12%.The HPV infection rate of adenocarcinoma was 88.46%.Among all the patients with cervical cancer and CIN,the infection rate of HPV16,the most genotype,was 88.98%.The infection rate of HPV18,the second most subtype,was 33.06%.In addition,the minority were infected HPV52、33、59、68.Among 48 cases of cervical squamous cell carcinoma,the infection rate of HPV16,HPV18 was 93.73% and 27.08% respectively.Among 23 cases of cervical adenocarcinoma,the infection rate of HPV16,HPV18 was 82.61% and 52.17% respectively.On the other hand,all the patients with cervicitis were HPV single infection.The HPV multiple infection rate of CINⅠ,CINⅡ/CINⅢ,cervical cancer was 20.00%,28.57%,36.62% respectively.CONCLUSIONS Gene chip technology can detect multiple HPV genotypes in paraffin-embedded tissues with high sensitivity and specificity,which is useful in the pathogenesis and prevention of cervical cancer.
