Breast Cancer Science Highlights

This session highlights six of the most clinically relevant abstracts within the Breast Cancer track of the 2022 ASTRO Annual Meeting Scientific Program. These noteworthy scientific abstracts share important findings and feature cutting edge research from leaders in the field. The Discussant compares and contrasts the current data to help you digest the latest science; places the study into context; and describes how the study can be put into clinical practice, if recommended. 
Highlighted Abstracts include – 

  • NRG RTOG 1005: A Phase III Trial of Hypo fractionated Whole Breast Irradiation with Concurrent Boost Versus Conventional Whole Breast Irradiation Plus Sequential Boost following Lumpectomy for High Risk Early-Stage Breast Cancer 

  • Physician Rated Cosmesis and Patient Reported outcomes after Concomitant Boost (CB) versus Sequential Boost (SB) for Adjuvant Treatment of Breast Cancer: A Prospective Randomized Study
