Radiotherapy vs Neck Dissection for Clinical T1/2N0 Supraglottic Cancer

Supraglottic cancer is a main type of laryngeal carcinoma, which is one of the most common head and neck tumors. Cervical nodal metastasis is an important prognostic factor in supraglottic cancer. Current management, following the US National Comprehensive Cancer Network guidelines for T1-2, N0 supraglottic cancer (NCCN 2017), is either definitive radiotherapy or primary surgery with or without neck dissection. The optimal neck treatments strategy remains unclear in clinical settings owing to the limitation of a small number of retrospective studies and a lack of prospective trials. The investigators conducted a prospective, randomised trial to compare radiotherapy with neck dissection.
