Background: The aim of this study is to analyze the results of radical surgery followed by postoperative radiotherapy in patients with advanced laryngeal cancer.
Methods: Seventy-seven patients with advanced laryngeal cancer were treated with postoperative radiotherapy following total laryngectomy with or without neck dissection. Median age of patients at the diagnosis was 57 years (range, 43-76). The median follow-up was 41 months (range, 11-70). Radiotherapy was performed using three-dimensional conformal technique.
Results: Median duration of overall radiation treatment time was 5.9 weeks (range, 5.4-7.6). Median total dose delivered was 60 Gy (range, 50-66). Locoregional relapse was the most frequent pattern of failure. A 5-year locoregional control (LRC) and overall survival (OS) rates were 72.3% and 66.2%, respectively. A 5-year LRC and OS rates were significantly higher in patients without nodal disease (N0) as compared to patients with metastatic involvement of the neck lymph nodes (N+) (p=0.009 and p=0.002, respectively). Confluent mucositis was developed in 16 patients (20.8%). Late toxicity most frequently occurred in the skin as well as in the mucous membrane and in the subcutaneous tissue and was grade 1 reaction (74.0%, 67.5%, and 72.7%, respectively).
Conclusion: In order to improve treatment results in terms of LRC and OS and following evidence-based treatment recommendations for patients with advanced laryngeal cancer whose initial treatment was radical surgery, we strongly advocate the acceptance of postoperative concurrent chemoradiotherapy in cases with surgical specimen demonstrating high-risk pathological features. |
