Impact of a fiducial marker based ART strategy on margins in postoperative IMRT of gynecological tumors

Adjuvant pelvic radiotherapy is used after hysterectomy in gynecologic cancers to reduce recurrences and improve progression free survival (1 –4). Currently, Intensity Modulated radiotherapy (IMRT) or Volumetric Modulated Arc Therapy (VMAT) is applied to reduce the dose to normal tissues and subsequently decrease acute and long-term toxicity (5–11). However, to prevent geometrical misses, the use of these highly conformal techniques r equires accurate margins that account for organ motion, set up and delineation errors.
