Abstract:
OBJECTIVE: The aim of this study was to identify human papilloma virus(HPV) infection in cervical lesions by using polymerase chain reaction in situ hybridization(PCR-ISH) and to compare the results of PCR-ISH with conventional in situ hybridization(ISH) METHODS: Forty-seven randomly chosen neutral-buffered formalhyde-fixed cervical biopsies in which cervical intraepithelial neoplasia and invasive cervical cancer had been diagnosed were tested for HPV DNA by PCR-ISH and ISH. The method of PCR-ISH includes deparaffinization of specimens, PCR amplification of DNA, in situ hybridization and detection of amplified products. RESULTS: The positivity rate of ISH was 36% for all biopsies and 26%, 40% for CIN and invasive cancer respectively. By using PCR-ISH the positivity was 80%, 84% respectively. All PCR-ISH positive cases were ISH positive and no ISH positive was PCR-ISH negative. CONCLUSION: In our study HPV DNA, undetectable by standard in situ hybridization, was detectable by PCR in situ hybridization. Our study shows that PCR in situ hybridization is highly sensitive method for detection of HPV in cervical neoplastic specimens with morphological evidence.
