    摘要: Pancreatic adenocarcinoma has the worst overall mortality of any solid tumor, with only 7% of patients surviving after 5 years. To evaluate the clinical implications of genomic alterations in this low cellularity tumor type, we deeply sequenced the genomes of 101 enriched pancreatic adenocarcinomas from patients who underwent potentially curative resections and used non-invasive approaches to examine tumor specific mutations in the circulation of these patients. These analyses revealed somatic mutations in chromatin regulating genes including MLL and ARID1A in 20% of patients that were associated with improved survival. Liquid biopsy analyses of cell free plasma DNA revealed that 43% of patients with localized disease had detectable circulating tumor DNA (ctDNA) in their blood at the time of diagnosis. Detection of ctDNA after resection predicted clinical relapse and poor outcome, and disease recurrence by ctDNA was detected 6.5 months earlier than with standard CT imaging.

    摘要: Provided herein are methods of detecting circulating tumor DNA, cancer cell mutations, and/or cancer cells harboring one or more cancer cell mutations. In some embodiments, methods provided herein include detecting one or more genetic alterations in cell-free DNA. In some embodiments, methods provided herein for detecting one or more genetic alterations in cell-free DNA can be performed when the subject is not known to harbor a cancer cell and/or a cancer cell mutation (e.g., when the subject is not known to harbor a cancer cell having the cancer cell mutation).
