Combination of Permanent Interstitial 125I-Seed Brachytherapy and Surgery for the Treatment of Large Hepatocellular Carcinoma
The treatment methods available for large primary hepatocellular carcinomas (diameter >5 cm) are inadequate. Here, we report the successful management of 80 cases of large hepatocellular carcinoma, using a combination of custom-designed permanent interstitial iodine-125 seed brachytherapy and palliative surgery. Patients were enrolled in the study between 2011 and 2014. All patients underwent s...
متن کاملInfluence of body mass index and periprostatic fat on rectal dosimetry in permanent seed prostate brachytherapy
PURPOSE We examined the influence of body mass index (BMI) and body fat distribution on rectal dose in patients treated with permanent seed brachytherapy for localized prostate cancer. METHODS AND MATERIALS We analyzed 213 patients treated with I125 seed brachytherapy for localized prostate cancer. BMI and rectal dosimetry data for all patients were available. Data on visceral and subcutaneou...
متن کاملModification of Source Strength in Low-Dose-Rate Lung Brachytherapy with 125I and 103Pd seeds
Background:Â A new treatment approach for most patients who have undergone early stage non-small-cell lung carcinoma (NSCLC), is wedge resection plus permanent implant brachytherapy. However, the specification of dose to medium at low energies especially in heterogeneous lung is unclear yet.Objective:Â The present study aims to modify source strength for different configurations of 125I and 103...
متن کاملDosimetry Comparison of Water Phantom and Complete Eye Definition for 125I and 103Pd Brachytherapy Plaques
Introduction: In this paper, by complete definition of human eye containing the various parts and their materials, the difference between this model and a homogeneous water phantom are compared for two ophthalmic plaques using 125I and 103Pd. Material and methods: The simulation of the two phantoms were performed in the MCNP-4C code and by using the geometry of a three-dimensional eye, differen...
متن کامل125I Seed Implant Brachytherapy for Painful Bone Metastases After Failure of External Beam Radiation Therapy
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...
