Clinical Study of Styping Detection of Human Papillomavirus (HPV) Infection with Microarray from Paraffinembedded Specimens of Cervical Cancer and Precursor Lesions.

Abstract

The prevalence and type distribution of human papillomavirus (HPV) in cervical cancer and cervical intraepithelial neoplasia (CIN) in Jiangsu, China was investigated. A total of 93 cases with cervical cancer and 176 CINII-III tissue samples were obtained from women undergoing biopsy or surgery. The 1047 exfoliated cervical cell samples were collected with cervical brush in physical examination women. HPV DNA and typing were examined by polymerase chain reaction (PCR) and gene-chip. The results showed that HPV DNA was detected in 82 cases with cervical cancer (88.17%), HPV 16 being detected in 65 (69.89%) cases, HPV 18 in 12 (12.90%) cases, HPV 33 in 10 (10.75%) cases, HPV 31 in 4 (4.30%) cases, and HPV 45 in 3 (3.23%) cases. HPV DNA was detected in 154 cases with CINII-III (87.50%), HPV 16 being detected in 92 (52.27%) cases, HPV 18 in 50 (28.41%) cases, HPV 33 in 25 (14.21%) cases, HPV 58 in 25 (14.21%) cases, and HPV 31 in 20 (11.36%) cases. About 20.43% cervical cancer and 38.64% CINII-III specimens exhibited multiple infections (p < 0.01). The total positive rate, single infection and mixed infection rate of the CINII-III and SCC group all had a significant difference (p < 0.05) when compared with the normal cells group. The total positive rate, single infection rate and mixed infection rate of CINII-III group did not show significant difference (p > 0.05) when compared with SCC group. CINII-III and SCC had all intimate relation with HPV infection. The high prevalence of HPV 16, 18, 33, 31 and 58 in Jiangsu (China) deserves more attention, as it has important implications for the successful use of HPV vaccine and choice of diagnostic methods.
