Brachytherapy dose received by bladder and rectum in patients with inoperable cervical cancer: CT-based 3D view

Abstract

As recommended by the GEC-ESTRO work group, it is important for the 3D image guided CT, or MRI based brachytherapy of cer-A B C Dvical cancer to verify what dose is received by 0.1 cm 3 , 1 cm 3 and 2 cm 3 (D 0,1cc , D 1cc and D 2cc , respectively) of the bladder and rectum volume (1). Intracavitary brachytherapy was applied with applicators type Fletcher tandem and ovoids, once a week on a HDR regime (high dose rate). Delineation of organs at risk (bladder and rectum) was made after each computer tomography (Panel A). The bladder and rectum were delineated on each
