tumor sequencing workflow
The systematic process of collecting, processing, analyzing, and reporting genomic data from cancer specimens to identify clinically actionable mutations and guide treatment decisions.
Full Definition
A tumor sequencing workflow encompasses the comprehensive process of genomic analysis from initial specimen collection through final clinical reporting and treatment recommendations. This workflow typically begins with tissue collection and quality assessment, followed by DNA/RNA extraction, library preparation, and next-generation sequencing. Bioinformatics pipelines then process the raw sequencing data to identify mutations, copy number variations, and other genomic alterations. The workflow concludes with clinical interpretation, where identified variants are assessed for therapeutic significance and incorporated into structured reports for healthcare providers. In oncology informatics, these workflows must integrate with laboratory information systems, clinical databases, and decision support tools to ensure seamless data flow and timely delivery of actionable results.
Usage
Usage note: Hyphenate when used as a compound modifier: 'tumor-sequencing workflow standards.'
