Youssef Zeidan, MD, PhD, of the American University of Beirut Medical Center, discusses study findings showing that, in patients with one to three positive lymph nodes, postmastectomy radiation treatment decreased the risk of locoregional recurrence, particularly in estrogen receptor–positive disease (Abstract 83).
David Routman, MD, of the Mayo Clinic, discusses his study findings showing that detectable human papillomavirus circulating tumor DNA in the postoperative setting may be linked to disease progression, which may help improve patient selection for treatment intensity (Abstract LBA5).
Daniel M. Trifiletti, MD, of the Mayo Clinic, discusses study findings showing that, between two different radiation doses (30 Gy/10 fractions vs 37.5 Gy/15 fractions), there was no difference in the time to cognitive failure, tumor control, or overall survival for patients with brain metastases (Abstract 19).
Steven H. Lin, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses phase II findings that showed proton beam therapy improved total toxicity burden score with no difference in progression-free survival when compared with intensity-modulated radiation treatment (Abstract LBA2).
Erica H. Bell, PhD, of The Ohio State University, discusses phase III findings from a prognostic and predictive molecular subgroup analysis of radiotherapy vs radiotherapy plus procarbazine/lomustine/vincristine in high-risk low-grade gliomas (Abstract 161).
Daniel E. Spratt, MD, of the University of Michigan, discusses phase III study findings showing that 2 years of antiandrogen therapy increased cardiac and neurologic toxicities, as well as mortality from causes other than prostate cancer, in men with low levels of prostate-specific antigen after prostatectomy who received adjuvant early salvage radiotherapy (Abstract LBA1).
