What is the Best Way to Plan Rectum Three-Dimensional Conformal Radiotherapy in Prone Position —Classic Anatomical Landmark, Three Dimensional Fitting the Planning Target Volume, or Volumetric Modulated Arc?
Traditionally, rectal cancer radiation therapy uses bony landmark fields to cover common lymphatic drainage sites, including the internal iliac, presacral, and perirectal lymph nodes. We aimed to investigate if bony landmark borders sufficiently cover the internal iliac nodes and to compare tumor volume and normal tissue avoidance using classic bony landmarks (c3DCRT), contoured elective clinical target volume (f3DCRT), and volumetric modulated arc therapy (VMAT) planning in locally advanced rectal cancer.
