Development and validation of a nomogram for prediction of survival and local control in laryngeal carcinoma patients treated with radiotherapy alone: a cohort study based on 994 patients.To advise laryngeal carcinoma patients on the most appropriate form of treatment, a tool to predict survival and local control is needed.
The impact of radiotherapy on swallowing and speech in patients who undergo total laryngectomy.OBJECTIVES: Quality of life studies have shown no detrimental effect with radiotherapy (RT) in patients who have a total laryngectomy. We wished to determine the effect of RT (initial or postoperative) specifically on the swallowing and voice function in patients treated by total laryngectomy (TL) for carcinoma of the larynx. DESIGN: Multicenter chart review. SETTING: Multicenter study in the Greater Manchester and Lancashire area. PARTICIPANTS: A total of 121 postlaryngectomy patients all of whom had completed definitive treatment at least 6 months before this study. Twenty-six patients had total laryngectomy as a single modality treatment and 95 had total laryngectomy and radiotherapy. MAIN OUTCOME MEASURES: Swallowing (solid food, soft diet or fluid/PEG) and voice development. RESULTS: Swallowing was better in the group who had no radiotherapy (P = 0.0037). There was no difference in voice function between the two groups. We also demonstrated that females had a worse swallowing outcome (P = 0.0101), as did advanced nodal stage (P = 0.001). CONCLUSIONS: RT adversely affects the swallowing results but not the speech results after TL when given either as initial treatment or postoperatively. This should be kept in mind in the decision-making process in the treatment of patients with carcinoma of the larynx.
Primary Radiotherapy for Carcinoma of the Retromolar Trigone; A Useful Alternative to Surgery.AIMS: Squamous cell carcinoma of the retromolar trigone is uncommon. The standard initial treatment is primary surgery, which usually involves microvascular reconstruction with a composite flap. Some patients are considered unsuitable for this procedure. This retrospective study examined the outcome and toxicity for patients with squamous cell carcinoma of the retromolar trigone treated with definitive radiotherapy in a single centre. MATERIALS AND METHODS: Between 1991 and 2000, 43 patients were treated with definitive radiotherapy with a median dose of 50Gy in 16 fractions over 21 days. Hospital case notes and radiotherapy records were analysed. RESULTS: The median age was 66 years (range 39-84 years). Nodal disease was evident in 13 (30.2%) patients. Twenty-one patients (51.2%) had stage I/II disease and 20 patients (48.8%) had stage III/IV disease. After a median follow-up of 59 months, 13 (30.2%) patients were alive and well, nine (20.9%) patients had died of an intercurrent illness and 21 (48.8%) had died of their disease. Five-year locoregional control was 46.5% (95% confidence interval 29.7-61.7), cause-specific survival was 45.7% (95% confidence interval 29.1-60.8) and overall survival was 30.9% (95% confidence interval 17.5-46.3). Osteoradionecrosis was documented in two patients. DISCUSSION: This hypofractionated regimen is convenient for this patient population and produced comparable outcomes to longer fractionation schedules without an increase in late toxicity.
