Head and Neck Pathology

Researchers 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.
