Systems Oncology
A framework for understanding cancer as a complex, interconnected and evolving system.
What Is Systems Oncology?
Systems Oncology is the study and clinical application of the interconnected biological, clinical and environmental factors that influence cancer initiation, progression, treatment response and survivorship.
Rather than focusing exclusively on tumor cells, Systems Oncology considers the interactions among tumor biology, genetic and epigenetic alterations, cancer metabolism, the tumor microenvironment, the immune system, conventional therapies, precision diagnostics, emerging approaches and patient-specific factors.
Why a Systems Approach?
Cancer behaves as a complex adaptive system. Tumor cells continuously interact with surrounding tissues, blood vessels, immune cells, extracellular matrix and distant organs. These interactions can influence growth, invasion, metastasis, treatment response and resistance.
Tumors Evolve
Cancer changes over time. New biological characteristics may emerge as tumors adapt to their environment and treatment.
Biological Pathways Interact
Metabolism, immunity, inflammation, angiogenesis and other pathways can influence one another simultaneously.
The Tumor Environment Matters
Stromal cells, immune cells, blood vessels and the extracellular matrix can influence tumor progression and treatment response.
Treatment Changes the System
Therapeutic interventions can affect both tumor cells and their surrounding biological environment.
Patients Are Individuals
Patient characteristics influence treatment tolerance, response and outcomes.
Care Requires Reassessment
Cancer management requires ongoing evaluation rather than relying on a single treatment plan throughout the disease journey.
The Nine Domains of Systems Oncology
The Systems Oncology framework brings together nine interconnected domains that influence cancer behavior and treatment outcomes.
Cancer Biology
The molecular and cellular mechanisms underlying malignant transformation, proliferation, invasion, metastasis and tumor evolution.
Cancer Metabolism
Changes in glucose metabolism, glutamine utilization, fatty acid oxidation and mitochondrial function that support tumor growth and survival.
Tumor Microenvironment
Stromal cells, immune cells, extracellular matrix, blood vessels and other components surrounding and influencing the tumor.
Cancer Immunology
The interaction between malignant cells and the immune system, including immune surveillance and immune escape.
Conventional Oncology
Surgery, radiotherapy, chemotherapy, immunotherapy, targeted therapy and hormonal therapy remain the foundation of evidence-based cancer care.
Precision Diagnostics
Histopathology, molecular profiling, imaging, liquid biopsy and biomarkers provide information for diagnosis, treatment selection and monitoring.
Repurposed Drugs & Nutraceuticals
Medications and nutraceuticals being investigated for potential anticancer effects and their possible place within an integrated approach.
Lifestyle & Supportive Care
Nutrition, physical activity, rehabilitation, symptom management, psychosocial support and palliative care throughout the cancer journey.
Clinical Decision Support
Structured integration of clinical, pathological, molecular, radiological and patient-specific information to support clinical decision-making.
Putting the Pieces Together
Systems Oncology does not replace conventional cancer treatment. It provides a framework for understanding how different aspects of cancer biology, diagnosis, treatment and patient care fit together.
