For patients who had two HPV-positive blood tests after treatment, the test was 94 percent accurate in detecting cancer recurrence.<\/p>\n<p>\u201cThe major utility of this test is it\u2019s going to improve our ability to monitor patients after they complete treatment,\u201d said UNC Lineberger\u2019s\u00a0<a href=\"https:\/\/unclineberger.org\/directory\/bhishamjit-s-chera\/\">Bhisham Chera, MD<\/a>,\u00a0associate professor in the UNC School of Medicine Department of Radiation Oncology. \u201cCurrently, our methods to assess whether the cancer has recurred are invasive, expensive and not always accurate.\u201d<\/p>\n<p>Infection with certain strains of HPV can cause cervical cancer, genital cancers and cancer of the oropharynx, which is the back of the throat, including the base of the tongue and tonsils.<\/p>\n<p>With the goal to improve cancer tracking, UNC Lineberger researchers designed a test to detect HPV genetic material that dying cancer cells have released in to the blood. Intellectual property for a form of the experimental test was licensed to Naveris Inc.<\/p>\n<blockquote><p>\u201cWe developed a technology that enabled us to distinguish HPV DNA that came from a tumor from HPV that\u2019s simply related to infection,\u201d said UNC Lineberger\u2019s\u00a0<a href=\"https:\/\/unclineberger.org\/directory\/gaorav-gupta\/\">Gaorav Gupta, MD, PhD<\/a>,\u00a0assistant professor in the UNC School of Medicine Department of Radiation Oncology and Biochemistry and Biophysics.<\/p><\/blockquote>\n<figure id=\"attachment_12011\" class=\"thumbnail wp-caption alignleft\" style=\"width: 310px\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-12011\" src=\"https:\/\/www.med.unc.edu\/biochem\/wp-content\/uploads\/sites\/795\/2019\/11\/Gupta-300x200-300x200.jpg\" alt=\"Gaorav Gupta MD PhD\" width=\"300\" height=\"200\" \/><figcaption class=\"caption wp-caption-text\">Gaorav Gupta, MD, PhD<\/figcaption><\/figure>\n<p>In their latest study, researchers evaluated 115 patients who underwent chemotherapy and radiation treatment for oropharyngeal squamous cell carcinoma linked to HPV16.<\/p>\n<p>Patients were screened for recurrence using PET\/CT body scans, chest imaging, and physician evaluations. They received a blood test every six to nine months.<\/p>\n<p>\u201cFor this study, we systematically applied our assay to over 1000 patient blood samples obtained from the clinical study,\u201d said Sunil Kumar, PhD postdoctoral fellow at UNC Lineberger.<\/p>\n<p>Initially, 28 patients had a positive HPV blood test, indicating a possible recurrence, but only 15 of those patients were diagnosed with recurrence based on a biopsy.<\/p>\n<p>When 28 patients who initially received a positive test result underwent a second blood test, only 16 were found to be HPV positive.<\/p>\n<p>That indicated to researchers that two consecutive positive blood tests indicated a recurrence, and led to a sensitivity level for the test of 94 percent.<\/p>\n<p>\u201cIn this study, we had accumulated enough follow-up data to see who was going to develop recurrence and who wasn\u2019t,\u201d Gupta said. \u201cThat allowed us to determine that the test performs best if you look at two consecutively confirmed blood tests.\u201d<\/p>\n<p>Meanwhile, for 87 patients who had negative HPV blood tests in all their screening sessions, none developed recurrence.<\/p>\n<p>Chera said the experimental test could improve follow-up screening for this type of head and neck cancer, which can involve imaging every six months or annually, and inserting a scope into the nose and down the throat every two to three months in the first two years after a person completes treatment.<\/p>\n<p>\u201cWith this new technology, it offers a noninvasive way to accurately monitor patients for cancer recurrence,\u201d Chera said. \u201cIn the long run, blood-based surveillance could be more effective, and possibly help us to detect cancer sooner.\u201d<\/p>\n<p><em>In addition to Chera, Gupta and Kumar other authors included Sunil Kumar, PhD; Colette Shen, MD, PhD; Robert Amdur, MD; Roi Dagan, MD; Rebecca Green, MSW; Emily Goldman, BS; Jared Weiss, MD; Juneko Grilley-Olson, MD; Shetal Patel, MD, PhD; Adam Zanation, MD; Trevor Hackman, MD; Jeff Blumberg, MD; Samip Patel, MD; Brian Thorp, MD; Mark Weissler, MD; Wendell Yarbrough, MD, MMHC, FACS; Nathan Sheets, MD; William Mendenhall, MD; and Xianming M.
