Bradley R. Pieters, MD, PhD, is Head of the Brachytherapy department and Principal Investigator at the Amsterdam University Medical Centers, location AMC, The Netherlands. Dr. Pieters is the past-chair of the GEC-ESTRO and the Course Director of the European Society for Therapeutic Radiology and Oncology (ESTRO) School for the Comprehensive and Practical Brachytherapy course. Dr. Pieters was trained in Radiation Oncology at the Radboud University Hospital in Nijmegen, The Netherlands, and received his medical degree in 1990. He completed his residency in radiotherapy at Academic Hospital Nijmegen, The Netherlands. Dr. Pieters then completed a brachytherapy fellowship at the Daniel den Hoed clinic in Rotterdam and L'Institut Gustave-Roussy in Villejuif, France. His brachytherapy training was completed at the Academic Medical Center in Amsterdam. Dr. Pieters received his MSc in epidemiology in 2006 and his PhD in 2010 after defending his thesis “Pulsed-dose rate brachytherapy in prostate cancer.” Dr. Pieters’ main field of interest is general brachytherapy with an emphasis on urologic brachytherapy, gynecologic brachytherapy, and translational research for advanced and automatic treatment planning in the field of brachytherapy. Dr. Pieters is currently one of the Principal Investigators of the PROBACH trial (Randomized Phase 3 Study on the Assessment of Late Toxicity by Comparing IMRT High Dose External Beam Radiotherapy Only With External Beam Radiotherapy Combined With HDR or PDR Brachytherapy in Patients With Intermediate/High Risk Prostate Cancer) and the POWER trial (Randomized trial for the evaluation of erectile dysfunction after whole or partial gland prostate brachytherapy). He is also working on the following research projects: quantification of treatment-induced growth disruption using 3D photography in children with (orbital) rhabdomyosarcoma; ICT-based innovations in the battle against cancer – next-generation patient-tailored brachytherapy cancer treatment planning; Fast, accurate, and insightful brachytherapy treatment planning for cervical cancer through artificial intelligence; The impact of bowel motility on the radiotherapy dose to the bowels.
