Estimation of Dose Received by Sensitive Organs in Radical External Radiation Therapy of Cervical Carcinoma

Abstract

The main objective of this study was to estimate dose received by sensitive organs in cervical carcinoma irradiation, out of 200 patients referred to Radiation and Isotopes Center of Khartoum (RICK), that patients received a radical radiotherapy course for stage I and II without hematologic spread. The collected variables were the organs position and depth, patient’s separations, equivalent field size, percentage depth dose DD% and back scatter factor. The graphs and correlation were carried out using EXCELL software under windows and the analysis of results showed that: the bladder, cervix and rectum were situated parallel to each other from anterior to posterior respectively and they have linear correlation in depth wise with patient separation. The result of this study showed that the average dose received by OAR ‘bladder, rectum, and head of femur’, were 4611 ± 400.3, 4449±553.7 and 4611 ± 439.7 respectively.
