Abstract
We combined molecular hybridization and histological analysis of 58 biopsy samples from the uterine cervix to correlate the presence of certain strains of human papillomaviruses (HPVs) with specific pathological changes. HPV sequences were frequently detected (85%) in biopsies that contained a broad spectrum of precancerous changes. The presence of HPV 16 correlated strongly with precancers that exhibited morphological aberrations commonly found in invasive carcinomas and precancers that have a high risk of progression. This association underscores the potential importance of HPV type 16 in the genesis of genital cancers and emphasizes the value of histological analysis for detecting potentially oncogenic HPVs.
