tumor genomic landscape
Comprehensive molecular characterization of all genetic alterations present within a tumor sample.
Full Definition
The tumor genomic landscape represents the complete spectrum of molecular alterations identified through comprehensive genomic profiling of cancer tissue. This landscape includes single nucleotide variants, insertions and deletions, copy number alterations, structural rearrangements, and mutational signatures that collectively define the tumor's molecular identity. Understanding the genomic landscape enables identification of therapeutic targets, resistance mechanisms, and prognostic markers. Clinical reports describing genomic landscapes must prioritize actionable findings while providing context for non-actionable alterations.
Usage
Usage note: Use 'landscape' not 'profile' when emphasizing comprehensive molecular characterization.
