Scientists develop world's first test of saliva for oropharynx cancer
Scientists from Queensland University of Technology have developed the world's first saliva test for oropharynx cancer, aimed at people without cancer symptoms.
According to Medical Express, human papillomavirus (HPV) often causes oropharyngeal cancer. It is possible to identify this infection and thus people at risk by the presence of HPV DNA in saliva.
Scientists conducted a study of 665 healthy people. According to them, if the initial test shows the presence of HPV-16 DNA, and the second test gives the same results, it is necessary to conduct a more detailed examination to detect cancer.
Experts give an example of a patient in whom HPV-16 DNA was fixed for 36 months, with an ever-increasing concentration of the virus, as evidenced by studies conducted after 6, 12, and 36 months from the date of detection.
As a result, the patient was found to have squamous cell carcinoma of 2 mm in the left tonsil, which was subsequently removed, which increased the patient's chances of recovery. After surgery, traces of HPV-16 DNA in saliva were not recorded.
