Human papillomavirus in breast carcinomas of Korean women.

Abstract

Abstract Abstract #3086 Introduction
 The association between human papillomavirus (HPV) and cervical cancer is well documented. However, it remains unclear whether there is also a correlation between HPV infection and human breast cancer. The aim of this study was to investigate the status of HPV-DNA in breast carcinoma of Korean women and to examine the possible association between HPV and breast cancer development.
 Patients and Methods
 We examined the HPV-DNA of 154 patients including 123 cases of breast carcinoma, 31 cases of intraductal papilloma, and 27 cases of adequate nipple from cancer patients using DNA-chip method.
 Results
 The HPV-DNA was detected in 8 breast carcinomas (6.5%), but in none of the intraductal papillomas. All detected HPV was high-risk groups; the HPV-18 and HPV-70 were found in each two cases and each one cases HPV-16, 31, 56/58 and 59. In one case of nipple, both low-risk (HPV-62) and high-risk (HPV-18) group HPV-DNA was obtained. The papillary carcinomas and the invasive ductal carcinomas with adjacent intraductal papillomas showed slightly increased incidence (11% vs. 3-4%), however, there was no significant difference. No correlation between the presence of HPV-DNA and specific prognostic predictors for the disease outcome was observed.
 Conclusions
 Our results suggest that the presence of high-risk group HPV in the breast might be related to breast carcinogenesis, especially papillary phenotype. Further studies are warranted. Citation Information: Cancer Res 2009;69(2 Suppl):Abstract nr 3086.
