  • Patent number: 9157129
    Abstract: The present invention provides probes and methods of use thereof in the diagnosis and/or prognosis of certain types of cancers, particularly human papillomavirus (HPV)-associated cancers. The probes are designed for hybridization with genomic material in a manner indicative of one or more aberrations in the genetic material present in the test sample. The identified aberrations are biomarkers of HPV-associated cancer. The methods of the invention comprise contacting a sample to one or more probes, allowing any genetic material in the sample to hybridize to the genomic regions provided in the probes, analyzing the hybridizations, and analyzing the hybridizations to identify detected aberrations as biomarkers indicative of HPV-associated cancer progression.
