OBJECTIVE: In image-guided EBRT of the prostate, transperineal ultrasound (US) probes exert pressure on the perineum both during planning and treatment. Through tissue deformation and relaxation, this causes target and risk organ displacement and drift. In this study, prefraction shift and intrafraction drift of the prostate are quantified during robotic transperineal 4DUS. METHODS: The position of the prostate was recorded for different positions of the probe before treatment in 10 patients (16 series of measurements)...

INTRODUCTION: Race may be a significant factor that influences prostate cancer (PCa) survival, with the Asian (AsA) race being associated with better outcomes compared to African American (AA) and Non-Hispanic Whites (NHW). This study evaluates race-dependent variation in PCa-specific mortality (PCSM) associated with radiation dose-escalation exemplified by external beam radiotherapy (EBRT) with a brachytherapy (BT) boost in Gleason score 8-10 PCa. METHODS: 28,956 men diagnosed with clinically localized PCa and Gleason score 8-10 from 2004-2013 who received EBRT, EBRT with a BT boost, or radical prostatectomy (RP) were identified using the Surveillance, Epidemiology, and End Results (SEER) database...

INTRODUCTION: Targeted intraoperative radiotherapy (TARGIT - IORT) as a tumour bed boost after breast conserving surgery is well established for women with early breast cancer. A previous study from our group shows a beneficial effect of TARGIT-IORT on overall survival (OS) but not disease-free survival (DFS) after neoadjuvant chemotherapy compared to an external boost suggesting a potential non-inferiority of TARGIT-IORT. In this study we present results regarding the high-risk subset of patients (i...

PURPOSE: Local recurrence (LR) of prostate cancer after external beam radiotherapy (EBRT) is a serious problem. Our purpose was to determine if reduced-dose salvage brachytherapy could achieve high rates of biochemical control with acceptable toxicity if combined with androgen deprivation therapy (ADT). METHODS AND MATERIALS: Thirty-three consecutive patients with LR after EBRT were treated with salvage brachytherapy plus ADT from 1998 to 2013. All had pathologically confirmed LR, disease-free interval ≥18 months after EBRT, no distant/nodal metastasis, and International Prostate Symptom Score ≤15...
