Peter R. Galle, MD, on Atezolizumab/Bevacizumab vs Sorafenib for Hepatocellular Carcinoma: Patient-Reported Outcomes
2020 Gastrointestinal Cancers Symposium
Peter R. Galle, MD, of the University Medical Center, Mainz, discusses patient-reported outcomes from this phase III study, which showed the combination of atezolizumab plus bevacizumab vs sorafenib is well tolerated and may represent a new standard of care in the first-line setting for unresectable liver cancer (Abstract 476).
Thomas Yau, MBBS, of the University of Hong Kong, discusses this triplet combination, which yielded better responses than doublet combination therapy in patients with advanced liver cancer, but with more severe adverse events and more treatment discontinuations (Abstract 478).
Zev A. Wainberg, MD, of the UCLA Medical Center, discusses the first subset analysis of how a combined positive score in gastric and gastroesophageal junction cancers related to the efficacy of pembrolizumab in PD-L1–positive disease (Abstract 427).
Brian M. Wolpin, MD, of Dana-Farber Cancer Institute, discusses a noninvasive blood test evaluating methylation of circulating free DNA. In his study, the blood test detected multiple gastrointestinal cancers at a sensitivity of approximately 81% and a prespecified specificity of > 99%. It also accurately localized the tissue of origin across more than 20 cancer types (Abstract 283).
Danielle S. Bitterman, MD, of the Harvard University Radiation Oncology Program and Massachusetts General Hospital, discusses an analysis of genomic and clinical data from 97 patients with pancreatic ductal adenocarcinoma with circulating tumor DNA. Mutations were most frequently detected in patients with locally advanced and metastatic disease (Abstract 753).
Thibaud Kössler, MD, PhD, of Geneva University Hospital, discusses the first trial to study the efficacy and safety of anti–PD-1 immunotherapy plus short-course radiotherapy in localized microsatellite-stable rectal cancer. The study explores whether a gene signature can predict sensitivity to immunotherapy (Abstract TPS272).
