Detection of human papillomavirus DNA from the breast carcinomas and the cervix: Are they correlated?
1544 Background: The association between human papillomavirus (HPV) and cervical cancer is well known. However, it remains unclear whether there is also a correlation between HPV infection and human breast cancer. The aim of this study is to investigate the hypothetic association between HPV infection and breast carcinoma through the comparison of the type of HPV infection in the breast and cervix. Methods: From April to December 2008, 106 patients who were diagnosed as breast cancer and underwent mastectomy were analyzed. Their breast tissue (tumor, normal parenchyme, and nipple-areolar complex) and cervix smear were analyzed for HPV infection with DNA chip microarray method. Results: 24 patients (23.1%) showed HPV infection in their cervix smear; high-risk type of HPV was found in 12 patients. But only six patients (5.8%) revealed the HPV infection in breast cancer; half of them were high-risk group (HPV-16, 31); the same types of HPV was found at the normal breast tissue in two patients of them. However, there were no patients with HPV infection in both breast and cervix concurrently. Conclusions: There were no positive results for HPV infection of cervix in HPV-infected breast cancer patients. Also, we cannot find that the presence of high-risk HPV in the breast might be related to the breast carcinogenesis. We concluded that HPV infection is not correlated to the carcinogenesis of breast. No significant financial relationships to disclose.
