“…Damin et al found 25% of HPV positivity in 101 breast cancer tissues [14]; moreover, Kroupis et al [6] showed a 16% rate of HPV positivity in more than 100 breast cancer tissue specimens, and they suggested a correlation between infection and elevated tumour grading and proliferation index over a low ER+ expression. However, Lindel et al [26] did not support these findings.…”

“…Additional studies have reported a high prevalence of HPV DNA in breast cancer of women with a history of cervical pre-malignant and malignant lesions [17][18][19], suggesting that HPV DNA may migrate through bloodstream from the original site of infection to the breast, or alternatively, may be transmitted by hand from the female perineum to the breast. In contrast to the studies cited above, no DNA from low-risk and high-risk HPV types was detected in several other independent studies using type-specific and/or consensus PCR primers in Paget's diseases, papillomas, papillary carcinomas and infiltrating ductal breast carcinomas [20][21][22][23][24][25][26]. In particular, Gopalkrishna et al reported that when breast cancer cells were collected by aspiration with a fine needle to avoid any possible contamination of surrounding tissues, no HPV DNA was detected in the tumour tissue [22].…”

“…According to a study, HPV is mainly found on the dermis of the breast and travels through the nipple and ducts, infects the breast tissue and starts the potential malignant process (De Villiers et al, 2005). Since the mechanism is not clear, it is quite probable that additional cofactors are needed to immortalize and transform the infected breast cells (Lindel, 2007).…”

“…1) zeigen beispielhaft die Spannbreite und Diskrepanz der publizierten Daten bezüglich der Inzidenz von HPV in Tumoren. So konnten mehrere Studien eine solche Assoziation nicht nachweisen, und die Autoren lehnen daher eine kausale Rolle des Virus in der Kanzerogenese ab [6,18], während andere auf den positiven Nachweis beharren und die Ergebnisse als gesichert ansehen [5,10]. Es wurden mittlerweile Hypothesen entwickelt, unter welchen Bedingungen es zu einer Infektion und Transformation des Brustdrüsenepithels kommen kann [15].…”

“…Daneben fallen Unterschiede in der geografischen Verteilung der Studien auf. Während die negativen Ergebnisse in der Regel an zentraleuropäischen -Schweiz und Frankreich [6,18] -und amerikanischen Patientenkollektiven erhoben wurden [21], fanden sich die positiven Ergebnisse gehäuft in Asien, speziell Taiwan [16], Lateinamerika/Brasilien [4,5] oder auch der Türkei [2]. Insofern spielen regionale Unterschiede bezüglich der Inzidenz von HPV in der Normalbevölkerung eine nicht unwichtige Rolle bei der Interpretation der Ergebnisse wie auch der möglichen Assoziation mit der Tumorentstehung.…”
