DEMONSTRATION OF LOW-FREQUENCY OF HUMAN PAPILLOMAVIRUS DNA IN CERVICAL ADENOCARCINOMA AND ADENOCARCINOMA INSITU BY THE POLYMERASE CHAIN-REACTION AND INSITU HYBRIDIZATION

There is evidence that cervical adenocarcinoma is increasing in incidence, particularly in young women. In order to assess the possible role of human papillomaviruses in cervical glandular oncogenesis, 16 cases of invasive adenocarcinoma and eight cases of adenocarcinoma in situ have been examined by in situ DNA hybridization using biotinylated probes to human papillomavirus types 6, 11, 16, 18, and 31, and assessed by polymerase chain reaction analysis for human papillomavirus types 11, 16, and 18 sequences. Of the invasive adenocarcinomas, four of 16 contained human papillomavirus type 16 sequences and of 16 contained type 18 sequences as assessed by polymerase chain reaction analysis. Only one invasive adenocarcinoma and one case of adenocarcinoma in situ showed a positive in situ hybridization signal. The low rate of carriage of the human papillomavirus sequences examined suggests that these viral types may not play a major role in cervical glandular neoplasia.
