Malignancies of the Nasal Cavity and Paranasal Sinuses: Long-Term Outcome With Conventional or Three-Dimensional Conformal Radiotherapy

Local failure remains the dominant cause of poor outcome for patients with sinonasal cancer, despite aggressive local treatment with combined surgery and radiotherapy in operable patients. Distant metastasis and certainly regional relapse were much less common sites of failure. Overall survival remains poor, suggesting the need for more efficacious local and possibly systemic therapy.
