Abstract
Laryngeal cancer is one of the most common malignant cancer of the head and neck. Concurrent chemoradiotherapy is considered by the NCCN guideline to be the most effective organ protection strategy for locally advanced laryngeal cancer, which can preserve the larynx without reducing the survival rate of patients. Patients with non-T4 （T1-3） and high lymph node burden （N2-3） laryngeal cancer can benefit from concurrent chemoradiotherapy, which are more suitable for concurrent chemoradiotherapy than locally advanced laryngeal cancer with other stages. The indications of concurrent chemoradiotherapy were further discussed in this paper.
