External beam radiotherapy is a safe and effective curative treatment modality for men with localized prostate cancer (PCa). While traditionally entailing long courses with low daily doses, an appreciation of prostate radiobiology and advancements in radiation delivery have allowed for more abbreviated courses of EBRT. Ultrahypofractionated radiotherapy, which involves the delivery of >5 Gy/fraction, is now considered a standard of care regimen for localized PCa, especially intermediate-risk disease. Stereotactic body radiotherapy (SBRT), a specific form of ultrahypofractionated radiotherapy that utilizes advanced planning, imaging, and treatment technology to deliver in ≤5 fractions, is in particular emerging as a cost-effective, convenient, and safe alternative to longer courses of radiotherapy...
