Reduced toxicity with equivalent outcomes using three-dimensional volumetric (3DV) image-based versus nonvolumetric point based (NV) brachytherapy in a cervical cancer population

摘要

PURPOSE: Brachytherapy (BT) techniques have historically used a two-dimensional nonvolumetric (NV) system involving dose prescribed to a point fixed in space. We compared dosimetric, toxicity, and oncologic outcomes for volumetric planning (3DV) versus CT point -based planning.
