Brian M. Wolpin, MD, on Performance of a Blood-Based Test for the Detection of Multiple Cancers 
    		2020 Gastrointestinal Cancers Symposium
    	
    	
    	
    
        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).
    
    
    
    
       
       
    		
		
		
        
		
		
		
		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).
			
			
     	
    
       
       
    		
		
		
        
		
		
		
		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).
			
			
     	
    
       
       
    		
		
		
        
		
		
		
		Van K. Morris, MD, of The University of Texas MD Anderson Cancer Center, discusses the COBRA study, which is examining circulating tumor DNA and its ability to predict whether patients with resected stage IIA colon cancer may benefit from adjuvant chemotherapy (Abstract TPS261).
			
			
     	
    
       
       
    		
		
		
        
		
		
		
		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).
			
			
     	
    
       
       
    		
		
		
        
		
		
		
		Scott Kopetz, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses phase III findings from the BEACON CRC trial, which had demonstrated that the triplet regimen of encorafenib, cetuximab, and binimetinib significantly improved overall survival in patients with a BRAF V600E mutation. The new analysis showed that the regimen also led to substantial improvement in patient-reported quality of life compared with current standard of care (Abstract 8).
