Summary
Brief summary (as posted)
This project aims to propose a new approach in the treatment of solitary plasmacytoma: hypofractionated irradiation alone with stereotactic technique that may contribute to the successful treatment of this disease. This work aims to apply this new technique with the primary objective of reducing the progression-free survival for multiple myeloma of patients treated for solitary plasmacytoma, as well as quantify overall survival, local control, toxicities and quality of life in a phase I trial / II.
