Outcomes of Patients with Primary Sacral Chordoma Treated with Definitive Proton Beam Therapy

We conducted a retrospective analysis to evaluate the safety and efficacy of definitive proton beam therapy with 70.4 Gy (relative biological effectiveness) in 32 fractions for primary sacral chordoma. This cohort study of 33 eligible patients shows that this treatment modality is safe and effective, and has the potential to reduce pain.
