Comparison between Three-Dimensional Conformal Radiation Therapy (3DCRT) and Intensity-Modulated Radiation Therapy (IMRT) for Radiotherapy of Cervical Carcinoma: A Heterogeneous Phantom Study.

Background: Radiotherapy plays a major role in the treatment of the cervical cancer.

Objective: Dosimetric comparison of intensity-modulated radiation therapy (IMRT) with three-dimensional conformal radiation therapy (3DCRT) in cervical cancer treatment was performed by modifying the beams arrangements to achieve better organ at risk (OAR) sparing.

Material And Methods: The analytical evaluation study was made by modifying the IMRT plan, subtracting the rectal volume from planning target volume (PTV), and applying the field-in-field technique in 3DCRT.

Dose-volume analysis of acute gastrointestinal complications in cervical cancer undergoing definitive concurrent chemoradiation.

Context: Definitive concurrent chemoradiation with brachytherapy is the prime modality of treatment of cervical cancer. The small bowel is one of the critical organs responsible for gastrointestinal complications.

Aims: This study aims to analyze the relation of small bowel dosimetric parameters with the incidence of acute gastrointestinal complications.
