A research team including the Univeresity of Osaka, Okayama University, and The institute of Science have identified burrowing oral cancer genes that could help doctors diagnose difficult cases earlier and avoid treatment delays. They studied 23 cases of oral cancer with a burrowing growth pattern and found that rare carcinoma cuniculatum has a unique genetic fingerprint. The research found genetic alterations in FAT1, NOTCH1, PIK3CA, and CASP8, suggesting a potential explanation for its slow growth and favorable prognosis. These findings suggest that genetic testing could improve diagnosis and inform treatment decisions in oral cancer.
