Precision oncology faces challenges beyond static genomic alterations, requiring dynamic integration of tumor evolution, host biology, and systemic factors for improved cancer care. Future strategies emphasize adaptive, longitudinal, and systems-based approaches for sustained patient benefit.
Area of Science:
- Oncology
- Genomics
- Systems Biology
Background:
- Precision oncology, guided by biomarkers, has advanced cancer care but offers limited durable benefit.
- Treatment failure is influenced by dynamic tumor evolution, host biology, and systemic pressures, not just static genomic alterations.
Purpose of the Study:
- To review biological, technological, clinical, and systemic barriers limiting precision oncology's effectiveness.
- To explore emerging concepts in evolutionary oncology and non-genetic resistance mechanisms.
Main Methods:
- Narrative review of literature from PubMed, MEDLINE, and Web of Science (2015-2026).
- Focus on therapeutic resistance, tumor microenvironment, longitudinal monitoring, biomarkers, multi-omics, adaptive trials, implementation science, and healthcare disparities.
Main Results:
- Precision oncology is shifting towards adaptive, longitudinal, and systems-oriented management.
- Key limitations include integrating tumor evolution, host factors, and real-time biomarker dynamics into decision-making.
Conclusions:
- Future progress requires longitudinal molecular monitoring, adaptive therapeutic sequencing, and integrated tumor-host frameworks.
- Equitable learning healthcare systems are crucial for advancing precision oncology.
