Abstract:
Despite recent advancements in multidisciplinary treatments, the overall survival and quality of life of patients with advanced head and neck squamous cell carcinoma (HNSCC) have not improved significantly over the past decade. Molecular targeted therapies, which have been addressed and advanced by the concept of "oncogene addiction", have demonstrated only limited successes so far. To explore a novel clue for clinically effective targeted therapies, we analyzed the molecular circuitry of HNSCC through the lens that HNSCC is an evolving system. In the trajectory of this somatic evolution, HNSCC acquires biological robustness under a variety of selective pressures including genetic, epigenetic, micro-environmental and metabolic stressors, which well explains the major mechanism of "escaping from oncogene addiction". On the other hand, this systemic view appears to instruct us approaches to target latent vulnerability of HNSCC that is masked behind the plasticity and evolvability of this complex adaptive system.
Insights
Head and neck squamous cell carcinoma (HNSCC) evolves to resist targeted therapies. Viewing HNSCC as an evolving system reveals vulnerabilities for developing new treatments.
Area of Science:
- Oncology
- Systems Biology
- Cancer Evolution
Background:
- Advanced head and neck squamous cell carcinoma (HNSCC) shows limited survival improvements despite multidisciplinary treatments.
- Current molecular targeted therapies, based on oncogene addiction, have yielded modest clinical success in HNSCC.
Purpose of the Study:
- To investigate the molecular circuitry of HNSCC by conceptualizing it as an evolving system.
- To identify novel therapeutic strategies by understanding HNSCC's adaptive mechanisms.
Main Methods:
- Analysis of HNSCC molecular circuitry.
- Application of a systems biology approach to study cancer evolution.
- Examination of HNSCC's response to various selective pressures.
Main Results:
- HNSCC exhibits biological robustness through somatic evolution, enabling it to overcome oncogene addiction.
- The study frames HNSCC as a complex adaptive system with inherent plasticity and evolvability.
Conclusions:
- A systems-level understanding of HNSCC evolution is crucial for overcoming treatment resistance.
- Targeting latent vulnerabilities within this complex adaptive system may lead to more effective therapies for advanced HNSCC.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
