tumor genomic landscape
The comprehensive pattern of genetic alterations characteristic of a specific cancer type or individual tumor sample.
Full Definition
The tumor genomic landscape represents the comprehensive molecular terrain of genetic alterations that define either a specific cancer type or an individual patient's tumor. This landscape encompasses the full spectrum of genomic aberrations including point mutations, insertions/deletions, copy number variations, structural rearrangements, and epigenetic modifications that collectively shape tumor biology. Understanding genomic landscapes has revealed cancer-type-specific patterns of genomic instability, mutational processes, and evolutionary constraints that inform both basic cancer biology and therapeutic targeting strategies. These landscapes are increasingly used for tumor classification, prognosis determination, and treatment selection.
Usage
Usage note: Use to describe broad genomic patterns rather than specific individual alterations.
