Lymph node ratio predicts RT benefit for oral cancer
By Cynthia E. Keen
Radiation therapy (RT) can benefit some patients with oral cavity squamous cell carcinoma, but they can suffer acute as well as long-term toxicities. The use of lymph node ratios may help identify which patients will benefit the most, according to an article published online in Radiotherapy and Oncology.
