The Vaginal Cylinder: Misunderstood, Misused, or Trivial?

Despite the fact that vaginal cylinder is a very common brachytherapy (BT) treatment and despite its apparent simplicity, the impact of dose schedules, prescription point, and treatment length are little understood. In this work we investigate the radiobiological impact of dose prescription parameters on dose distribution within a standard planning target volume (PTV) for high-dose-rate (HDR) BT vaginal cylinder treatments at a single institution. An insight on the magnitude of effects and their likely clinical relevance is given by retrospectively analyzing outcomes.
