Radiation should be performed by high-energy linear accelerators. Three-dimensional radiation treatment planning was used in all cases. Patients will be immobilized in a foam cradle in a supine position, and the treatment planning CT was obtained. Tumor mapping should be performed according to treatment planning CT and the diagnostic CT before induction chemotherapy. Treatment planning was performed with the isocenter calculated at 100% and the 95% line encompassing the planning target volume. The spinal cord was limited to 4600cGy. If one kidney was to receive more than 20Gy then more than 90% of the remaining kidney was excluded from the primary beam. Generally, a three-field no-axial beam arrangement (opposed lateral with an anterior-inferior oblique) was used.
