The purpose of this study was to evaluate the safety and therapeutic efficacy of computed tomography (CT)-guided I seed implant brachytherapy in patients with painful metastatic bone lesions after failure of external beam radiation therapy (EBRT).From August 2012 to July 2014, 26 patients with painful bone metastases after failure of EBRT were treated with CT-guided I seed implant brachytherapy...

PURPOSE The aim of this study was to use permanent seed implants in the breast and describe our experience with 15 cases, using iodine seed implants as a tumor bed boost. METHODS AND MATERIALS Breasts were fixed with a thermoplastic sheet, a template bridge applied, the thorax scanned and the images rotated to be perpendicular to the implant axis. Skin, heart, and lung were delineated. A prep...

The purpose of this study was to evaluate the efficacy and safety of high-dose-rate (HDR) brachytherapy of a single implant with two fractions plus external beam radiotherapy (EBRT) for hormone-naïve prostate cancer in comparison with radical prostatectomy. Of 150 patients with localized prostate cancer (T1c-T2c), 59 underwent HDR brachytherapy plus EBRT, and 91 received radical prostatectomy. ...

PURPOSE Permanent low-dose-rate (LDR-BT) and temporary high-dose-rate (HDR-BT) brachytherapy are competitive techniques for clinically localized prostate radiotherapy. Although a randomized trial will likely never to be conducted comparing these two forms of brachytherapy, a comparative analysis proves useful in understanding some of their intrinsic differences, several of which could be exploi...

PURPOSE To describe a breast-conserving technique using interstitial brachytherapy after lumpectomy and axillary nodal sampling in selected women who are diagnosed with breast cancer in the presence of augmentation mammoplasty. MATERIAL AND METHODS Over the past 20 years, we have developed and improved a technique of "pinch view" image-guided catheter insertion that avoids implant puncture. S...

Brachytherapy is a modality of treatment available for lung cancer with tracheal involvement. Correct positioning of the brachytherapy catheter is vital to the optimisation of treatment effect and reduction of complications. Normal airway anatomy and tumour location can make this positioning difficult. The current study presents the case of a 65-yr-old male with invasive tracheal squamous cell ...

PURPOSE Once implanted, prostate brachytherapy seeds are vulnerable to loss and movement. A general estimation of these effects may be useful for making patient care decisions when seeds are lost after the post-implant scan. The goal of this work was to explore the dosimetric and radiobiological effects of the types of seed loss and migration common in prostate brachytherapy. METHODS This stu...
