COMPARATIVE STUDY OF CONFORMAL HDR BRACHYTHERAPY WITH ICRU POINTS DOSES AND TOXICITY ASSESSMENT

Abstract

Background: Toxicity assessment is done by comparing HDR brachytherapy with ICRU point doses. D2cc doses of OAR in HDR brachytherapy is slightly more than ICRU point doses. Objectives:The primary objective is volumetric dose assessment and toxicity comparison between ICRU point doses and HDR brachytherapy. Materials and Methods: It is a prospective comparative study. The total number of patients enrolled in the study is 20. After obtaining informed consent, then patients were enrolled in the study. All patients were diagnosed with H.P.E. positive squamous cell carcinoma of the Cervix from stage IIB to IIIB. Results: HDR brachytherapy-based D2cc of Rectum is more than ICRU point doses of the rectum. bladder doses does not show any significant changes. Conclusion: Comparatively HDR D2cc doses are more than conventional doses for rectum.
