Conventional versus virtual simulation for radiation treatment planning of prostate cancer: final results.

Radiotherapy is widely used to treat patients with prostate cancer. Using conventional x-ray simulation is often difficult to accurately localize the extent of the tumor, to cover exactly the lymph nodes at risk and shield the organs at risk. We report on the results of a study comparing target localization with conventional and virtual simulation.One hundred prostate cancer patients underwent both conventional and virtual simulation. The...
