Oral squamous cell carcinoma(OSCC)is the most common oral cancers worldwide,accounting for over 90%of all oral malignancies[1].Despite encouraging improvements in therapeutic approaches,including surgical resection,chemotherapy,and radiotherapy,the five-year overall survival rate of OSCC has not been improved significantly over the past decades,mainly due to the high ratio of tumor recurrence and metastasis.
