Answer

Despite the successful completion of several prospective randomized trials evaluating 3D-CRT in the management of prostate cancer, several issues remain unclear. 3D-CRT is generally considered appropriate in the following circumstances:

  • The probability that tumor remains within the anticipated target portals (ie, delineation of the GTV, CTV, and PTV for organs at risk) can be adequately determined

  • The importance of regional adenopathy in varying clinical settings can be delineated
