World-first saliva test detects hidden throat cancer
Source: www.miragenews.com Author: staff A simple saliva test developed by Queensland University of Technology (QUT) biomedical scientists has detected early throat cancer in a person who had no symptoms, and no clinical signs of cancer. QUT researchers Associate Professor Chamindie Punyadeera and Dr Kai Tang. A series of saliva HPV tests detected an asymptomatic throat cancer during a trial of a new saliva diagnostic Further validation studies are needed to confirm this finding It is a world-first discovery, previously there was no screening test for HPV-DNA oropharyngeal cancers The patient had surgery in which a 2mm cancer was removed and has had no recurrence of HPV-DNA in his saliva. In what is believed to be a world-first, the non-invasive test picked up HPV-DNA in a saliva sample from an infected healthy person. Persistent human papillomavirus (HPV) infection is now the leading cause of cancers in the oropharynx (tonsils and tongue base area of the throat). “The series of saliva tests raised the alert and detected an early cancer before the person had any symptoms,” said QUT Faculty of Health’s Associate Professor Chamindie Punyadeera, who, with Dr Kai Tang developed the test. “This enabled removal of the tonsil which had a 2mm cancer in it, by straightforward local surgery alone. “The incidence of high-risk human papillomavirus (HPV)-driven throat cancers is on the rise in developed countries and, unfortunately, it is often discovered only when it more advanced, with patients needing complicated and highly impactful treatment. “In the US, HPV-driven throat cancers [...]
