Role of Postoperative Radiotherapy in T1-T2N0M0 Glottic Carcinoma Involving the Anterior Commissure

There remains no uniform treatment modality for glottic laryngeal carcinoma. Current clinical guidelines broadly recommend surgery or radiotherapy as single modality treatment for early stage glottic laryngeal carcinoma. Glottic carcinoma with anterior commissure invasion is linked to inferior local control; both definitive radiotherapy alone or transoral laser microsurgery (TLM) may confer a higher risk of local recurrence compared with other glottic carcinomas. We hypothesize that postoperative radiotherapy can act as an effective adjunct to surgery and reduce recurrence rates in patients with glottic carcinoma involving the anterior commissure. This study aims to conduct a multicenter, prospective, single arm phase II clinical trial of intensity modulated radiotherapy (IMRT) for postoperative patients with early stage glottic laryngeal carcinoma and anterior commissure involvement, to preliminarily evaluate the effect of IMRT on local control rates and long term survival outcomes in this patient population.
