Outcomes

Cyberknife Radiosurgery

PSA responses suggest long-term cancer control rates will be excellent (awaiting data from long-term studies)
One-millimeter accuracy protects surrounding tissues

External Beam Radiotherapy (EBRT)

Intensity-Modulated Radiotherapy (IMRT)

10+ year cancer-control outcomes inferior to brachytherapy; increasing the dose using image-guidance may improve results

Calypso-Guided EEBRT/IMRT

10+ year cancer-control outcomes inferior to brachytherapy; Calypso guidance may allow increase dose with improved results

High-Dose-Rate (HDR) Brachytherapy

Excellent cancer-control rates with 5-10 year follow-up

 

Low-Dose-Rate (LDR) Brachytherapy (Seed Implant)

Excellent cancer control rates with 10-15 year follow-up
Seeds positioned with 3-5 millimeters accuracy; occasionally some seeds migrate to the lung(s)
