Pivotal clinical trials and studies have highlighted advances in radiation therapy across multiple indications. Key findings show that pulsed low-dose-rate chemoradiation effectively reduces side effects in esophageal and non-small cell lung cancers without compromising efficacy. Additionally, the RadComp trial demonstrated comparable health-related quality-of-life outcomes between proton and photon radiation in breast cancer. In cardiac care, radiation therapy emerges as a promising noninvasive alternative for refractory ventricular tachycardia, potentially transforming treatment protocols. Collectively, these developments underscore significant strides in precision radiotherapy enhancing patient outcomes and comfort.
