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).
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).
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).
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).
Robert Olson, MD, of the BC Cancer Centre for the North, discusses a secondary analysis of the SABR-COMET trial, which showed there was a small magnitude decline in quality of life in both arms of the study but no associated detriment with stereotactic ablative radiotherapy (Abstract 148).
