Approximately 15% of human cancers can be attributed to viral infections. Polyomaviruses including simian virus 40, JC virus and BK virus, have been repeatedly isolated from various human brain tumours. However due to inconsistent findings, the etiologic role of polyomaviruses in brain tumours remains controversial. Human papillomaviruses (HPV) are an established causative agent of cervical cancers. Several studies suggested vertical transmission of HPV, suggesting that fetal exposure to HPV may contribute to childhood malignancy such as leukemia. Based on the aforementioned, we searched in 48 childhood brain tumour samples and 36 leukemia samples for the presence of polyomaviruses and HPV by PCR analysis, respectively. No viral DNA was detected in all samples by our highly sensitive 'neat and spike' PCR assay. Therefore, polyomaviruses probably do not play a major role in the pathogenesis of childhood brain tumours, and HPV is unlikely to be an etiological factor in childhood leukemia.
