Sexually transmitted papillomaviral infections. I. The anatomic distribution and pathologic grade of neoplastic lesions associated with different viral types.

Abstract

Multiple colposcopic biopsy specimens were collected from 160 women, with sampling of principal cervical and vulvar lesions as well as secondary areas of either minor acetowhitening or normal epithelium. Papillomaviral deoxyribonucleic acid was detected by Southern blot hybridization in 197 (90%) of the 218 principal biopsy specimens and 93 (46%) of 198 secondary biopsy specimens. Although different papillomaviruses were found at different sites in 31 women, only six of 416 specimens contained multiple types within the same sample. Specific viral types were associated with specific disease patterns. Only one of 80 type 6 or 11 infections had a diagnosis greater than cervical intraepithelial neoplasia, grade 2. In contrast, 42 of 48 (90%) biopsy specimens of cervical intraepithelial neoplasia, grade 3, or invasive cancer contained type 16, 18, or 31. Nonetheless, 12 of 124 (10%) cases of condyloma and cervical intraepithelial neoplasia, grade 1, were associated with types 16, 18, and 31 infections. Of 58 women with multicentric disease, 46 had positive hybridizations for both cervical and vulvar lesions (32 showing the same type in both samples and 14 showing different viruses). Differing patterns of papillomavirus-induced disease arise partly from the predilection of specific viral types for certain anatomic sites and partly through variations in host response. Detection of viral deoxyribonucleic acid in 46% of the secondary biopsy specimens suggests that disease expression may represent focal breakdown of host surveillance within a field of latent papillomaviral infection.
