title: Etiology of breast carcinoma: no apparent role for papillomavirus types 6/11/16/18.
abstract: A recent study has shown that human papillomavirus (HPV) types 16 and 18 can immortalize normal breast epithelium, and raised the possibility that HPV may be etiologically related to some cases of breast cancer. In order to investigate this possibility, we performed polymerase chain reaction (PCR) assays for HPV types 6, 11, 16 and 18 in 15 papillomas, 15 papillary carcinomas, and 13 infiltrating ductal carcinomas of the breast. No HPV-related DNA sequences were identified by Southern blotting of the PCR products. It therefore seems unlikely that a significant percentage of human breast carcinomas is etiologically related to infection with one of these HPV types.
