PURPOSE: To evaluate the clinical outcome of intensity-modulated radiotherapy (IMRT) in patients with mucosal melanoma (MM) of the nasal cavity and paranasal sinuses. PATIENTS AND METHODS: Between January 1999 and September 2004, eight patients with histologically proven MM of the nasal cavity and paranasal sinuses were treated with IMRT. A median dose of 66 Gy was applied to the macroscopic tumor (gross tumor volume [GTV]; range, 60-68 Gy) as an integrated boost and a median dose of 59 Gy (range, 54-64 Gy) to the clinical target volume (CTV) with IMRT. RESULTS: Treatment-related toxicity was very mild in most patients. Overall survival was 80% at 5 years. Calculated from treatment with IMRT as primary radiotherapy, survival was 100% at 1 year and 75% at 3 years. After IMRT, local progression-free survival was 71.4% at 1 year and 57.1% at 3 years, respectively. Distant progression-free survival after IMRT was 57.1% at 1 year and 28.6% at 3 years. CONCLUSION: Local dose escalation with IMRT yields good treatment results with respect to local and distant tumor control as well as survival, while treatment-related toxicity can be minimized.
