HUMAN PAPILLOMAVIRUS DETECTION IN CERVICAL ADENOCARCINOMA BY POLYMERASE CHAIN-REACTION

Twenty-five primary cervical adenocarcinomas and five cervical infiltrates from endometrial or rectal adenocarcinomas were analyzed for human papillomavirus (HPV) DNA by polymerase chain reaction with consensus and type-specific primers. Sixty-four percent (16 of 25) of the primary carcinomas and 20% (one of five) of the secondary infiltrates were positive for HPV types 16 and/or 18 DNA. Among the primary tumors HPV DNA was found in 80% of the endocervical cell-type tumors and in 60% of the endometrioid tumors, whereas two undifferentiated scirrhous carcinomas, one clear cell carcinoma, and one serous-papillary tumor were HPV negative. Human papillomavirus-positive patients were younger than HPV-negative patients (mean ages, 49.2 v 64.2 years). Our results indicate that papillomaviruses play a major role in the etiology of cervical adenocarcinomas, at least in premenopausal women. However, in contrast to other studies, HPV type 18 was not the predominant type of HPV, HPV types 16 and 18 occurring with similar frequency in our patients. © 1993.
