Twenty-five paraffin-embedded tumor tissues were analyzed for detection of HPV 16 and 18 in cervical adenocarcinoma by polymerase chain reaction with type specific primers and by non-radioactive Southern blot hybridization for confirmation . The suitability of paraffin-embedded tissue as PCR material was confirmed by successful amplification of 100% of cervical specimens with human -globin specific primer. Eighty four percent of the cervical adenocarcinoma tissues were positive for HPV 16 and/or 18. HPV 16 positive rate was 68%, HPV 18 was 60%. The double infection with HPV 16 and 18 was found in 44%. Three cases of the negative specimen in PCR for each type of HPV DNA 16 and 18 were positive in Southern blot hybridization. The total positive rate was 92% for HPV 16 and/or HPV 18, HPV 16 positive rate was 80%. HPV 18 was 72%. The double infection with HPV 16 and 18 was 60%. These results suggest that the pattern of HPV types 16 and 18 is closely associated with carcinogenesis of cervical cancers. HPV type 18 appears to be preferentially related to cervical adenocarcinoma and the poor prognosis of these patients. Therefore, determination of HPV DNA type in cervical carcinoma patients is important in treatment and prognosis.
