Patients with advanced lesions should have elective lymph node radiation therapy or node dissection. The risk of metastases to lymph nodes is increased by high-grade histology, large lesions, spread to involve the wet mucosa of the lip or the buccal mucosa in patients with recurrent disease, and invasion of muscle (i.e., orbicularis oris).[1]
