INTERDISCIPLINARY RADIOBIOLOGY CLINICAL BRACHYTHERAPY PHYSICS RTT YOUNG

TUESDAY 9 MAY 2017

Challenges remain in the radiobiological interpretation of moderate or extreme hypofractionation in prostate cancer.

Chair: K. Haustermans (Belgium) Co-chair: P. Agoston (Hungary)

11:00 > Moderate hypofractionation in prostate cancer: what have we learnt from phase 3 trials Speaker: D.P. Dearnaley (UK) 11:20 > Extreme hypofractionation – the future of prostate care or repeating past mistakes? Speaker: A. Loblaw (Canada) 11:40 > Hypofractionation in prostate cancer: a word of caution Speaker: S. Bentzen (USA) SYMPOSIUM Is there any ground for boost brachytherapy in the time of high precision IGRT/IMRT? 11:00 - 12:00 | SCHUBERT Three experts in the field of external beam irradiation (EBI), brachytherapy, and medical physics will review the role of brachytherapy boost in the era of high precision external beam IGRT/IMRT. Prof Ozsahin will show current EBI boost techniques in breast and GYN tumours including VMAT, Tomotherapy, CyberKnife, SBRT, and protons. Current evidence and challenges of SBRT/IMRT boost using IGRT will be presented. Prof Baltas will compare dose distributions of brachytherapy versus simultaneous integrated EBI boost techniques with special emphasis on dose gradient within the CTV. Dr Guinot will summarize the advantages of brachytherapy boost over EBI techniques including better conformity and sparing of normal tissues, steep dose gradient, and shorter overall treatment time. He will review long-term clinical evidence supporting the use of brachytherapy boost in multiple sites (e.g. prostate, GYN, breast, H&N, and anal canal).
