Radiation sigmoiditis mimicking sigmoid colon cancer after radiation therapy for cervical cancer: the implications of three-dimensional image-based brachytherapy planning
نویسندگان
چکیده
External-beam radiation therapy with intracavitary high-dose-rate brachytherapy is the standard treatment modality for advanced cervical cancer; however, late gastrointestinal complications are a major concern after radiotherapy. While radiation proctitis is a well-known side effect and radiation oncologists make an effort to reduce it, the sigmoid colon is often neglected as an organ at risk. Herein, we report two cases of radiation sigmoiditis mimicking sigmoid colon cancer after external-beam radiation therapy with intracavitary high-dose-rate brachytherapy for uterine cervical cancer with dosimetric consideration.

Out-Of-Field Dose Measurement and Second Cancer-Risk Estimation Following External Beam Radiotherapy and Brachytherapy for Cervical Cancer Treatment: A Phantom Study
Introduction: The present study aimed to measure the scatter and leakage dose received by out-of-field organs while delivering Radiotherapy (RT) treatment of cervical cancer. Moreover, this study estimated the risk of second cancer (SC). The doses to out-of-field organs were measured using a lithium fluoride (TLD 100) dosimeter while delivering External Beam Radiothera...

PURPOSE Distension and shape of urinary bladder may vary during intracavitary brachytherapy (ICBT) for cervical cancer, significantly affecting doses to bladder, rectum, sigmoid colon and small intestine and consequently late radiation toxicities. This study is to evaluate the effects of different fixed volume bladder distention on dosimetry, assessed by three dimensional image based planning, ...

Background: Brachytherapy treatment planning in cervix carcinoma patients using two dimensional (2D) orthogonal images provides only point dose estimates while CT-based planning provides volumetric dose assessment helping in understanding the correlation between morbidity and the dose to organs at risk (OARs) and treatment volume. Objective: Aim of present study is to compare Internationa...
