Chemoradiation for advanced oral and (pharyngo) laryngeal carcinoma: single institution outcome analysis.

Abstract Chemoradiation ( CRT) is a valuable treatment option for(pharyngo)laryngeal squamous cell cancer and a palliative cure in advanced oral cancers. However, toxicity is scarcely reported. Therefore, efficacy, acute and toxic effects of chemoradiation for advanced head and neck squamous cell carcinomas were evaluated, using retrospective study. Previously untreated patients with stage III-IV head and neck squamous cell carcinomas were included. Radiotherapy consisted of 70 Gy/7 weeks/35 fractions. All patients received concurrent Cisplatin 40 mg/m2 weekly. The most common acute toxic effects were dysphagia and mucositis. Dysphagia and xerostomia remained problematic during follow-up. Loco regional disease control was respectively 91% and 98% after 6 months. The median overall survival (calculating starting form the end of the treatment) was 33 months (range 0-111months). The 5-year disease specific survival was 41%. The results indicated that concurrent chemoradiotherapy for advanced head and neck squamous cell carcinoma is associated with high locoregional control and disease-specific survival. However, significant acute and long-term toxic effects occur, and organ preservation appears not necessarily equivalent to preservation of function in pharyngolaryngeal cancers.
