David Routman, MD, on Oropharyngeal Squamous Cell Carcinoma and HPV Circulating Tumor DNA
2019 ASTRO Annual Meeting
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).
Andrew Kneebone, MD, of Royal North Shore Hospital, discusses phase III study findings showing that at 5 years, biochemical control was similar between adjuvant and early salvage radiotherapies, the latter sparing half of the men potential side effects of radiotherapy without any significant compromise in outcome (Abstract 77).
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).
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).
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).
Alejandra Méndez Romero, MD, PhD, of Erasmus University Medical Center, discusses findings that show high local control rates with stereotactic body radiation for patients in this large published series, most of whom had colorectal cancer (Abstract 230).
