Abstract Objectives To evaluate the outcomes of advanced‐stage laryngeal squamous cell carcinoma (SCC) patients treated with functional‐preservation strategy with a specific focus on laryngo‐esophageal dysfunction disease‐free survival (LEDDFS). Methods and materials A retrospective review was conducted of stage III‐IVB laryngeal SCC patients who were treated with curative‐intent radiotherapy (RT) (2007–2018). Patients were preferentially managed with upfront chemoradiation (CCRT); except for those with cN2‐3, cT4, or large volume cT3 (induction chemotherapy followed by RT or CCRT is an option), and those who were unfit or declined chemotherapy (received altered RT). The primary endpoint was 3‐year LEDDFS, and secondary endpoints were 3‐year local failure (LF), regional failure (RF), distant metastasis (DM), overall survival (OS), disease‐free survival (DFS), and acute and late toxicities. Cox proportional hazard tests were used for multivariable analysis (MVA). Results A total of 213 cases were included. With a median follow‐up of 37 months, the 3‐year LEDDFS was 50%, while the 3‐year OS, DFS, LF, RF, and DM were 81%, 74%, 9%, 5%, and 7%, respectively. On MVA, cT4‐category was the only predictor of inferior LEDDFS (HR: 0.47, [95% CI: 0.29–0.74], p |
