RESUMEN
PURPOSE: To report outcome and toxicity of concurrent radiochemotherapy with carboplatin and paclitaxel in advanced squamous cell carcinomas of the oropharynx and hypopharynx. PATIENTS AND METHODS: Advanced inoperable carcinomas of the oropharynx and hypopharynx were treated with either hyper-fractionated, accelerated radiotherapy (50.0 Gy/2.0 with concomitant boost to 69.2 Gy/1.6) or conventional fractionated radiotherapy (70.2-72 Gy/1.8) concurrent with paclitaxel 40 mg/m2 and carboplatin AUC 1 weekly for 6 weeks. Acute and long-term toxicity was measured according to WHO- and CTC-criteria. RESULTS: A total of 84 patients were included between 2000 and 2008. Median follow-up time of patients alive was 36 months. Conventionally fractionated radiotherapy was given to 16 patients, while 68 patients were treated with concomitant boost. Finally, 88.1% of patients received full dose paclitaxel. Acute mucositis ≥ grade 3 was present in 51.2% of patients, while 6% of patients experienced ≥ grade 3 leucopenia and thrombopenia. A supportive gastric feeding tube was implanted in 89.1% of patients. Overall survival after 2 years was 46.3%, progression-free survival after 2 years was 41.0%. There was no significant survival difference between the different radiotherapy protocols. CONCLUSION: Concomitant carboplatin and paclitaxel is feasible and effective in advanced carcinomas of the head and neck.
