ASTRO Updates Guidelines, Recommending Shorter-Course Radiotherapy for Localized Prostate Cancer

The American Society for Radiation Oncology (ASTRO) has released updated clinical practice guidelines for hypofractionated external beam radiation therapy (EBRT) in localized prostate cancer. The new recommendations favor moderate hypofractionation over conventional fractionation across all risk groups and expand the role of ultrahypofractionation, potentially reducing treatment burden for patients.
