Implications of bladder volume on target coverage and dose to critical structures during high dose rate intracavitary brachytherapy for cervical cancer: A dosimetric study.

Background: The distension of the bladder during intracavitary brachytherapy (ICBT) affects the applicator position and in turn the dose to tumour and normal structures.

Aims And Objectives: To quantify the changes in the dose to high risk clinical target volume (HRCTV) and organs at risk (OARs) due to bladder filling.

Methods And Materials: In this prospective study, dosimetric parameters of 40 cervical cancer patients treated with (ICBT) were studied.

Efficacy of preoperative chemoradiotherapy in downstaging rectal cancer and its impact on the long-term outcome.

Introduction: Response to preoperative chemoradiation (PRTCT) for rectal cancer predicts the long-term outcome.

Context: Tertiary care hospital.

Aims: The aim is to study the factors affecting the response to chemoradiation.
