A Study of Image-Guided Intensity-Modulated Radiotherapy With Fiducials for Localized Prostate Cancer Including Pelvic Lymph Nodes

Conclusion: The use of prostate fiducials for daily localization during IMRT treatment results in negligible changes in dose coverage of pelvic nodes or normal tissue sparing in the absence of a significant systematic offset. This offers a simple and practical solution to the problem of image-guided radiotherapy for prostate cancer when including pelvic nodes.
