Research Abstract

1) DEFB4 CNV was observed in both cervical cancer and healthy control groups, and a lower DEFB4 copy number may be associated with susceptibility to cervical cancer, which is a population at high-risk of persistent oncogenic HPV infection. We found CNV of DEFB4 to be an additional host genetic susceptibility factor of cervical cancer. Further studies are required to determine the reproducibility of our findings in larger patient groups and different study populations.
2) we confirmed that common oncogenic HPV infection is associated with a higher risk of progression of cytological findings 2 years later in Japanese women with NILM or ASC-US; of these infections, HPV-16 was found to have a higher risk of progressive cytological findings than HPV-52. Therefore, the initial HPV-DNA genotype might be a potential predictive marker of later progression of cytological findings in the uterine cervix in Japanese women with NILM or ASC-US.
