Key Points

To assess the dosimetric impact and preliminary patient-reported outcomes of placing a rectal hydrogel spacer in patients undergoing 1.5T daily adapted MR-guided stereotactic body radiation therapy (SBRT) for prostate cancer.
Evaluated patients with prostate cancer undergoing 1.5T MR-guided daily adapted SBRT with an implanted rectal hydrogel spacer.
Assessed dosimetric treatment metrics and collected early patient-reported quality-of-life outcomes.
Observed preliminary dosimetric benefits to the rectum with the integration of a hydrogel spacer during MR-guided SBRT workflows.
Recorded initial patient-reported outcomes, though specific event rates and numerical effect sizes were not reported in the preliminary abstract.

Implication

Clinical study reports the dosimetric impact of rectal hydrogel spacers in MR-guided prostate SBRT, suggesting potential protection of adjacent organs.

Abstract

This the first experience reporting preliminary data concerning the potential dosimetric impact of rectal hydrogel spacer on MR-guided SBRT for prostate cancer.
