In this podcast, Dr. Fleure Gallant and Dr. Reshma Jagsi discuss a pivotal study by Busschaert et al. on the cost-effectiveness of Deep Inspiration Breath Hold (DIBH) in left-sided breast cancer radiotherapy. They highlight how DIBH significantly reduces heart radiation dose and cardiac events, while also noting its higher costs and impact on clinical workflow, ultimately concluding that DIBH remains a cost-effective option compared to free breathing techniques.
