VMAT plan quality comparison between Clinac-iX and halcyon treatment delivery systems for nasopharyngeal carcinoma.

Radiotherapy planning for nasopharyngeal carcinoma is a complex process due to the proximity of critical structures. Volumetric modulated arc therapy (VMAT) can improve the therapeutic ratio. However, multiple treatment delivery systems offer VMAT with varying technical specifications.

Racecadotril Versus Loperamide in Acute Radiation Enteritis: A Randomized, Double-Masked, Phase 3, Noninferiority Trial.

Purpose: There is currently no gold standard for the management of acute radiation enteritis. We compared the efficacy and safety of Racecadotril, an anti-hypersecretory drug, versus Loperamide, an anti-motility agent, in acute radiation enteritis.

Methods And Materials: We conducted a randomized, double-masked, non-inferiority trial at a single research institute.
