Objective: Intracavitary brachytherapy (ICBT) is the most critical part
of cervical cancer treatment which contains a combination of external and
intracavitary radiotherapy. We aimed to compare two different plans normalized to
point A and the high-risk clinical target volume (HR-CTV) in terms of the target
volume and doses for organs at risk (OARs). Methods: Twenty-eight
patients with small-residue cervical tumor volume who received CT-based
brachytherapy treatment with uterus tandem and double ovoid applicators were
included in the study. 3D-ICBT treatment plans normalized to HR-CTV and point A
were applied separately to five fractions. We made a total of 280 plans for the
two treatment techniques. The patients were given a dose of 5.5 Gy per fraction
for a total of 27.5 Gy in 5 fractions. The doses to OAR (rectum, sigmoid, and
bladder) and HR-CTV were compared between HR-CTV and point A - based plans.
Results: In the brachytherapy treatment planning, the mean doses of
HR-CTV D
