The current status of image-guided external beam radiotherapy for prostate cancer

Abstract

Purpose of review: To assess the current status and technological advances in image-guided external beam radiotherapy for prostate cancer.

Recent findings: Modern imaging has improved the ability to define radiotherapy target volumes. Specifically, treatment margins have been reduced through the use of treatment planning and image-guidance technology. Increasing dose has led to increased disease control. Concurrent technological advances may improve treatment-related toxicity. Data continues to emerge on patient selection, treatment schedule, and use of additional systemic therapy in conjunction with radiation.

Summary: In the present article, we review recent developments in radiation planning, image guidance, patient selection and fractionation, dose escalation, toxicity, systemic therapy, and follow-up.
