INCISE Mutational Data Subset: Index, Metachronous, and Synchronous Polyps

This study used formalin-fixed paraffin-embedded (FFPE) human tissue collected for the Integrated teChnologies for Improved polyp SurveillancE (INCISE) collaborative from polypectomies performed within the Scottish BCSP in the NHS Greater Glasgow and Clyde health board between 2009-2016 in patients who underwent further colonoscopy between 6 months and 6 years after the index colonoscopy. The extracted DNA was then passed to the Genomics Innovation Alliance (formerly Glasgow Precision Oncology Laboratory; GPOL) for genomic sequencing using their bespoke Cancer Plus panel. Some patients had metachronous polyps, and synchronous polyps sequenced, in addition to their largest index polyp. The output from the sequencing is FASTQ files and VCF files.
