Intensity-Modulated or Proton Beam Radiation Therapy Together with or without Cisplatin in Treating Patients with Stage III-IVB Paranasal Sinus and Nasal Cavity Cancer

Trial Status: closed to accrual

This phase II trial studies how well giving intensity-modulated radiation therapy (IMRT) or proton beam radiation therapy (PBRT) together with or without cisplatin works in treating patients with stage III-IVB paranasal sinus and nasal cavity cancer. Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving IMRT or PBRT together with cisplatin may kill more tumor cells.
