Initial experience and patient tolerance of proton stereotactic body radiotherapy.
This study reported treatment outcomes of 52 patients (62 lesions) treated with proton SBRT. Fractionation varied by indication and site with a median of 5 fractions and median fractional dose of 8 Gy. This study reported that proton-based SBRT can achieve dosimetric goals required by major clinical photon trials. There was no new grade 3 or greater toxicity during treatment. Comparing pretreatment to end of treatment timepoints, there was a significant improvement in patient reported outcomes, measured by the mean EQ-5D5L visual analogue score (VAS) (p = 0.014), and no significant change measured by the mean MD Anderson Symptom Inventory (MDASI) scores.
