Multi-Omics Integration

AI methods have become increasingly important in evaluating diverse and complex data from next-generation sequencing, integrating genomic, proteomic, and clinical data for comprehensive cancer characterization. 1

Critical Implementation Considerations

The Human-AI Partnership

A blend of AI and human expert judgment is essential for optimal outcomes, as human oversight remains crucial for patient-centric decision making, validation of predicted drug targets, interpretation of imaging data, and addressing ethical challenges. 1

Current Limitations and Pitfalls

Three major barriers limit AI integration into clinical oncology: 1

• Algorithm selection complexity: Choosing appropriate AI methods depends on data type, complexity, and clinical context 1
• Transparency requirements: Clinical integration demands detailed explanation and transparency of AI algorithms and their decision-making processes 1
• Quality monitoring: Continuous monitoring of AI tool performance is essential for robust clinical application 1

Data and Regulatory Challenges

Development and commercialization of AI software and devices face lengthy timelines due to regulatory limitations and extensive clinical trial requirements, despite demonstrated efficacy. 1

• Heterogeneous datasets, outcome biases, and data privacy concerns pose significant challenges 1
• Sparse reporting of actual AI methods used in oncology research prevents robust and reproducible science 1
• Ethical, legal, and social considerations require careful navigation 1
