Task: Answer Verification
Input (English): Question: Is intensity-Modulated Radiation Therapy Associated with Perioperative or Survival Benefit over 3D-Conformal Radiotherapy for Rectal Cancer?
Answer: IMRT is associated with worse local tumor control without any long-term survival benefit for patients with locally advanced rectal cancer. Given the lack of significant advantage and the higher cost of IMRT, caution should be exercised when using IMRT instead of traditional 3D-CRT for rectal cancer.
Output (English): no
