  2. Why Photon Boosts • 10-16 Gy • Decreased fibrosis • Enhanced local control • Deep seeded tumors https://www.google.com/search?site=&tbm=isch&source=hp&biw=1366&bih=624&q=radiation+breast+fibrosis&oq=radiation+breast+fibrosis&gs_l=img.3...1186.5828.0.6127.25.14.0.6.0.0.429.2251.0j1j4j1j2.8.0....0...1ac.1.48.img..18.7.2004.i3YbI13P1kI&gws_rd=ssl#facrc=_&imgdii=_&imgrc=YY5D-BJHUZlgqM%253A%3BEMF3Lh5Z_GOE1M%3Bhttp%253A%252F%252Fwww.aboutcancer.com%252Fbreast_image_tobias4.jpg%3Bhttp%253A%252F%252Fwww.aboutcancer.com%252Fbre4b.htm%3B258%3B208

  3. Why Not Use Photon Boosts • Larger field size • Small breast size • Shallow tumor

  4. Why Use Simultaneous Boost • 2 different volumes to 2 different doses each day • Adenocarcinomas • Enhanced local control • Decreased treatment time

  5. Why Not Simultaneous Boosts • Few patients fit the criteria • Increased acute side effects https://www.google.com/search?site=&tbm=isch&source=hp&biw=490&bih=639&q=linac&oq=linac&gs_l=img.3..0l10.2035.2961.0.3194.5.5.0.0.0.0.201.718.0j3j1.4.0....0...1ac.1.48.img..1.4.716.77l56vWY34M&gws_rd=ssl#q=radiation%20breast%20fibrosis&tbm=isch&facrc=_&imgdii=_&imgrc=shfnKM-PWp3BLM%253A%3BqCPg_UX-C-gHyM%3Bhttp%253A%252F%252F4.bp.blogspot.com%252F-d-QCEFty82I%252FTZvmDtBKvCI%252FAAAAAAAAHsY%252FmsuzW8oOF8M%252Fs1600%252FRadiation%252Bburn.jpg%3Bhttp%253A%252F%252Fdbrueckman.blogspot.com%252F2011%252F04%252Fmy-breast-cancer-journey.html%3B1600%3B1200

  6. Why Use Interstitial Boosts • Noninvasive Breast Brachytherapy Applicators (NIBB) • Decrease toxicity • Improve cosmetic outcomes • Decreased fibrosis https://www.google.com/search?q=interstitial+breast+brachytherapy&espv=2&source=lnms&tbm=isch&sa=X&ei=oCPFU5b5E8i-8QGN2oDwAw&ved=0CAYQ_AUoAQ&biw=780&bih=596#q=mammosite+radiation+therapy+system&tbm=isch&facrc=_&imgdii=_&imgrc=1zAL3oPzuyXlOM%253A%3B1hd5qK5wPT498M%3Bhttp%253A%252F%252Fwww.mammosite.com%252Fphysicians%252Fimages%252FRadiationProcedure.jpg%3Bhttp%253A%252F%252Fwww.mammosite.com%252Fphysicians%252Fradiation-therapy%252Fabout-mammosite.cfm%3B300%3B156

  7. Why Not Interstitial Boosts • Very invasive • Not many cancer centers do this procedure

  8. Why Use IOERT • 18-20Gy using Targeted Intraoperatve Radiotherapy(Targit) • Superb tissue localization • Sterilization • Decreased side effects • Mayo Clinic of Arizona Study

  9. Why not use IOERT • Machine cost • Expertise needed in OR

  10. Why Don’t We use These Alternatives More Often? • Availability • Cost Benefit
