INTRODUCTION Cervical carcinoma has traditionally been treated with low-dose-rate brachytherapy. High-dose-rate brachytherapy was developed to overcome potential disadvantages of LDR brachytherapy (radiation exposure to medical staff, prolonged treatment time, mandatory hospitalization and applicator movement). Both, LDR and HDR brachytherapy have been combined with the external beam therapy (E...

Pulsed Dose Rate (PDR) treatment is a new brachytherapy modality that combines physical advantages of high-dose-rate (HDR) technology (isodose optimization and radiation safety) with radiobiological advantages of low-dose-rate (LDR) brachytherapy. Pulsed brachytherapy uses a stronger radiation source than that employed in LDR brachytherapy and provides a series of short 10 to 30 minutes long ex...

BACKGROUND The aim of the study was to examine on the CT basis the inter-application displacement of the positions D0.1cc, D1cc and D2cc of the brachytherapy dose applied to the bladder and rectum of the patients with inoperable cervical cancer. PATIENTS AND METHODS This prospective study included 30 patients with cervical cancer who were treated by concomitant chemo-radiotherapy. HDR intraca...

Purpose: To evaluate the anxiety and pain levels of cervical cancer patients undergoing intracavitary multifraction high-dose rate (HDR) brachytherapy, as part a process to develop guidelines for quality patient-centered care. Methods: Cervical (n = 31) undergoingmultiple fraction HDR brachytherapy treatment at National Institute Oncology in Rabat (Morocco) completed ratings intensity using 11-...

PURPOSE During intracavitary brachytherapy (ICBT) for cervical cancer, the choice of applicator system remains rather arbitrary. However, as the applicator geometry may play an important role in dose distribution, thereby improving the therapeutic ratio, this study was conducted to compare the Manchester-style and Fletcher-style applicator systems. MATERIAL AND METHODS After completion of EBR...

PURPOSE This study assessed the trial of boost intracavitary brachytherapy (ICBT) for the patients of uterine cervical cancer with residual malignant cells detected at the final stage of ICBT. MATERIAL AND METHODS This is a retrospective analysis of 75 patients with cervical cancer treated radically with external beam radiotherapy and high-dose-rate intracavitary brachytherapy between August ...

PURPOSE The utility of serial simulations in vaginal vault irradiation is controversial. Our primary endpoint was to assess the significance of simulation in women who received adjuvant intracavitary high-dose-rate brachytherapy (HDR-BT) for early-stage endometrial adenocarcinoma. Secondary endpoints included assessment of acute and late treatment toxicity, medication requirements, and charges ...

A patient dose distribution was calculated by a 3D multi-group S N particle transport code for intracavitary brachytherapy of the cervix uteri and compared to previously published Monte Carlo results. A Cs-137 LDR intracavitary brachytherapy CT data set was chosen from our clinical database. MCNPX version 2.5.c, was used to calculate the dose distribution. A 3D multi-group S N particle transpor...
