tumor evolution tracking

Full Definition

Tumor evolution tracking involves serial molecular profiling to monitor how cancer genomes change during treatment and disease progression. This approach uses repeated tissue biopsies or liquid biopsies to track the emergence of resistance mutations, clonal selection pressures, and evolutionary bottlenecks. The data helps clinicians understand mechanisms of therapeutic resistance, predict treatment failure, and guide sequential therapy selection based on evolving tumor characteristics.

Usage

Usage note: Emphasizes temporal changes in tumor genetics rather than static profiling at diagnosis.
