However, a better understanding the performance assays is needed prior routine clinical use. As part an IRB-approved molecular profiling registry trial ductal adenocarcinoma (PDA) patients, we facilitated testing 34 patients from multiple community-based high-volume academic oncology practices. 23 these also underwent traditional tumor tissue-based testing. cfDNA was not detected 9/34 (26%) patients. Overall concordance between low, with only 25% sensitivity for NGS. Mutations KRAS, major PDA oncogene, were 10/34 (29%) samples, compared 20/23 (87%) presence mutations circulating associated reduced overall survival (54% mutation-positive versus 90% mutation-negative). Our results suggest that setting previously treated, advanced PDA, liquid biopsies are yet adequate substitute Further refinement defining optimal patient population timing sampling improve value test.
