Oral cancer has a poor survival rate linked to late detection. Only 60 percent of patients live beyond five years after diagnosis. Among black males, the survival rate is less than 38 percent. Scientists in Taiwan have already developed a new test to measure the amount of carcinogens attached to our DNA just by testing our spit. Researchers at the University of Texas have developed a new portable probe that could be used to diagnose oral cancer. The probe creates three dimensional images of areas within a tissue surface by illuminating the area with a laser. By taking numerous images and layering them on top of one another, it can deliver a large field of view.
The study plans to enroll 100-120 patients with white lesions or growths in their mouths and tonsil areas to test. The researchers will be looking for specific biomarkers that were previously identified by researchers at UCLA. These particular biomarkers have been shown in studies to confirm the presence of oral cancer.
If the clinical trial is successful in helping create a saliva test to detect the biomarker’s presence, doctors and dentists would have a better idea of which patients actually need biopsies. The test also has the potential to accelerate health care savings, he added, since the number of biopsies can be dramatically reduced.
A study of a potential saliva test for oral cancer is also going to be performed at the Michigan StateUniversity College of Human Medicine's Department of Surgery. It is to be done with collaboration with the Delta Dental of Michigan's Research and Data Institute. The study plan to create a simple, cost-effective saliva test to detect oral cancer.
