Intracavitary brachytherapy treatment has a very important role in patients with locally advanced cervical cancer. Brachytherapy is painful procedure, especially whom opening cannot be achieved, and requires analgesia immobilization. The American Association (ABA) recommends the use of conscious sedation as much possible intracavitary high-doserate (HDR) applications diagnosed In this review, w...

It has been suggested that pain control during intracavitary brachytherapy for cervical cancer is insufficient in most hospitals in Japan. Our hospital began using caudal epidural anesthesia during high-dose-rate (HDR) intracavitary brachytherapy in 2011. The purpose of the present study was to retrospectively investigate the effects of caudal epidural anesthesia during HDR intracavitary brachy...

Objective: In locally advanced cervical cancer, the management consists of external beam radiotherapy and brachytherapy. The impact of intracavitary brachytherapy versus interstitial brachytherapy on local tumor control, survival and complications were prospectively investigated in this study. Methods: A total of 60 patients with stage IIB, IIIB cervical cancer were treated using a combination ...

PURPOSE To assess the feasibility of applying trans-applicator intracavitary ultrasonography to image-guided brachytherapy for cervical cancer. MATERIAL AND METHODS For this experiment, a phantom was created and included a polyethylene tube, intended to simulate a tandem applicator, which was inserted into chicken meat and embedded in agar, along with magnetic resonance imaging (MRI)-compatib...

conclusions according to the results, the old dosimetry formalisms, overestimate the dose especially towards the applicator’s tip. while the tg-43u1 based software perform the calculations more accurately. results for a typical arrangement of 10 active pellets in the applicator, the percentage difference between doses obtained by the new algorithm at 1cm distance from the tip of the applicator ...

OBJECTIVE The aim of this study was to determine the efficacy of 252Californium neutron intracavitary brachytherapy using a two-channel Y applicator combined with external beam radiotherapy for the treatment of endometrial cancer. METHODS Thirty-one patients with stage I-III endometrial cancer were recruited for this study. The stage I patients received only 252Californium neutron intracavita...

PURPOSE The purpose of this case series is to describe the treatment and outcomes of a cohort of patients with inoperable early-stage endometrioid endometrial cancer with 3D image-guided high-dose-rate (HDR) intracavitary brachytherapy. MATERIALS AND METHODS A review was performed of patients with early-stage endometrial cancer who underwent primary radiation treatment between 2010 and 2016. ...

PURPOSE Intracavitary brachytherapy necessitates the insertion of a tandem applicator through the cervical os into the uterine cavity. Blind insertion of the tandem may result in suboptimal tandem placement. This decreases the control of the tumor locally and may result in uterine perforation. Although routine real time ultrasound guided tandem placement has shown better results, it is seldom p...

PURPOSE This study was designed to evaluate the dosimetric feasibility of definitive stereotactic body radiation therapy (SBRT) for the treatment of medically inoperable early stage endometrial cancer. METHODS CT simulation scans from 10 medically inoperable early stage endometrial cancer patients previously treated with high dose-rate (HDR) intracavitary brachytherapy were used to generate H...

Involvement of parametrial disease in locally advanced cervical patients poses a challenge for women undergoing brachytherapy. Current use of the Fletcher suit applicator may not adequately cover the high risk clinical target volume (HR CTV), especially in the parametrial region due to the physical qualities of brachytherapy from the inverse square law and the need to respect organs at risk (OA...
