High control rate in patients with chondrosarcoma of the skull base after carbon ion therapy: First report of long‐term results

Abstract

Carbon ion therapy is a safe and effective treatment in patients with chondrosarcoma of the skull base. For further evaluation, a prospective randomized phase 3 trial comparing protons versus carbon ions has been recruiting patients with low-grade and intermediate-grade chondrosarcoma of the skull base since 2009.
