title: Human papillomavirus DNA and virus-encoded antigens in cervical carcinoma.
abstract: The present study was undertaken to evaluate the prevalence of HPV in formalin-fixed, paraffin-embedded cervical carcinoma tissues using PCR followed by non-radioactive Southern hybridization with type-specific oligonucleotides for HPV 16 and 18. In addition, the tissue sections were immunohistochemically screened with two monoclonal antibodies, for expression of HPV 16 L1 and HPV 18 E6 proteins. A total of 57 of 60 cervical carcinomas (95.0%) were found with HPV using both techniques. HPV 16 and HPV 18 were present in equal proportions. Results of both DNA hybridization and immunohistochemistry were in agreement for the majority of the cases. HPV 16 and 18 DNA and virus-encoded antigens, L1 and E6 were found highly prevalent in these cervical carcinomas. Due to the high prevalence of HPV with cervical carcinoma in Malaysia, the implementation of routine diagnosis for the virus in cervical biopsies would be clinically useful.
