Prostate external beam radiotherapy combined with high-dose-rate brachytherapy: dose-volume parameters from deformably-registered plans correlate with late gastrointestinal complications
BACKGROUND Derivation of dose-volume correlated with toxicity for multi-modal treatments can be difficult due to the perceived need for voxel-by-voxel dose accumulation. With data available for a single-institution cohort with long follow-up, an investigation was undertaken into rectal dose-volume effects for gastrointestinal toxicities after deformably-registering each phase of a combined exte...
متن کامل[High-dose-rate brachytherapy with external beam radiotherapy for localized or locally advanced prostate cancer].
PURPOSE To evaluate the therapeutic outcomes and late toxicities in patients treated by high-dose-rate brachytherapy (HDR-BT) with external beam radiotherapy (EBRT) for localized or locally advanced prostate cancer. MATERIALS AND METHODS From May 2004 to September 2008, 86 men were treated by HDR-BT with EBRT for localized or locally advanced prostate cancer at the National Hospital Organizat...

PURPOSE To report outcomes on 5 patients treated with salvage partial low-dose-rate (LDR) 125-iodine ((125)I) permanent prostate seed brachytherapy (BT) for biopsy-proven locally persistent prostate cancer, following failure of dose-escalated external beam radiotherapy (EBRT). MATERIAL AND METHODS A retrospective review of the Fox Chase Cancer Center prostate cancer database identified five p...
متن کاملRegistering prostate external beam radiotherapy with a boost from high-dose-rate brachytherapy: a comparative evaluation of deformable registration algorithms
BACKGROUND Registering CTs for patients receiving external beam radiotherapy (EBRT) with a boost dose from high-dose-rate brachytherapy (HDR) can be challenging due to considerable image discrepancies (e.g. rectal fillings, HDR needles, HDR artefacts and HDR rectal packing materials). This study is the first to comparatively evaluate image processing and registration methods used to register th...
متن کاملLong-term biochemical results after high-dose-rate intensity modulated brachytherapy with external beam radiotherapy for high risk prostate cancer
BACKGROUND Biochemical control from series in which radical prostatectomy is performed for patients with unfavorable prostate cancer and/or low dose external beam radiation therapy are given remains suboptimal.The treatment regimen of HDR brachytherapy and external beam radiotherapy is a safe and very effective treatment for patients with high risk localized prostate cancer with excellent bioch...
