The growing complexity of cancer care, combined with rapidly evolving clinical guidelines and limited access to specialist oncologists, has presented significant challenges to timely and standardised cancer treatment. At the University of California at San Francisco (UCSF), this reality prompted the development of a robust artificial intelligence system. Rather than replace clinicians, the system was designed to support oncologists and general practitioners by automating information gathering, structuring clinical data and aligning recommendations with current national and institutional guidelines. This technology-driven approach has transformed oncology workflows, helping reduce treatment delays and allowing physicians to focus on personalised care.
Tackling Complexity with Technology
Cancer care today demands a precise and individualised approach due to the proliferation of disease subtypes and guideline updates. National bodies like the National Comprehensive Cancer Network, the American Cancer Society and the American Society of Clinical Oncology frequently revise their recommendations, often multiple times per year. Moreover, these national guidelines are not always aligned,and institutions often introduce their own protocols. This creates a confusing landscape for practitioners, particularly general practitioners who are increasingly tasked with managing early cancer care amid workforce shortages. Compounding the issue is the unstructured nature of patient data, requiring time-consuming reviews before oncologists can make evidence-based decisions.

UCSF’s AI system was designed to resolve these complications by automating the aggregation and structuring of clinical data, ensuring every oncology consultation begins with a comprehensive and up-to-date patient profile. It flags missing critical information, such as biopsies or genomic tests, in advance. Additionally, the system integrates institutional policies alongside national standards, enabling consistent and current recommendations. This not only reduces cognitive burden for clinicians but also ensures that patients across different care settings receive high-quality, evidence-informed care.
Deployment and Impact in Clinical Practice
The AI solution developed at UCSF was integrated into oncology workflows to support both general practitioners and oncology specialists. To validate its effectiveness, the clinicians assessed 100 anonymised cases—50 each of breast and colon cancer—under two scenarios: diagnosis-stage data and treatment-stage data. Each case was reviewed for completeness, accuracy of extracted decision factors and relevance of the AI-generated recommendations. These evaluations also included measuring the time required for clinicians to finalise treatment workups using the system.
The AI's two-pronged capability—automating data structuring and embedding clinical guidelines—ensured that oncologists were well-equipped at the point of care. Before consultations, the system consolidated patient histories and highlighted any missing diagnostic steps. During consultations, it presented guideline-based recommendations tailored to the specific case, enhancing decision quality while saving time. Importantly, the AI continuously updated its logic with new research and evolving guidelines, maintaining clinical relevance. Integration with electronic health records allowed seamless access to patient data while preserving confidentiality through de-identification.
The most prominent outcome was the significant reduction in time needed to review clinical information. Where manual review once took up to two hours, the AI enabled oncologists to complete the same task in just 10 to 15 minutes. Additionally, there was a 95% agreement between AI-generated recommendations and human clinical decisions, underscoring the system’s reliability. Equally critical was the AI's role in reducing diagnostic delays by prompting necessary tests earlier in the process—an improvement that directly contributes to faster treatment initiation.
Guidance for Future Implementations
The successful deployment of UCSF’s AI system offers a roadmap for other healthcare organisations seeking to incorporate artificial intelligence into cancer care. A foundational requirement is ensuring the AI tool has access to complete and accurate clinical data. Interoperability issues between various electronic systems often pose a barrier, but resolving these can significantly improve AI reliability and usefulness. Organisations must prioritise data standardisation and integration before moving forward with implementation.
Equally vital is maintaining the role of clinician oversight. AI systems should serve as decision-support tools, not replacements for medical judgment. Ensuring transparency in how recommendations are generated builds trust among physicians and encourages adoption. The UCSF model emphasised explainability, allowing users to trace the logic behind AI suggestions, thereby reinforcing the system’s credibility. Clinicians must also retain the authority to adjust or override recommendations as needed to ensure patient-centric decision-making.
Finally, thoughtful deployment is key to scalability. By embedding AI seamlessly into existing workflows and aligning its use with clinical responsibilities, organisations can enhance care quality without introducing additional burdens on staff. In this way, AI becomes a facilitator of efficiency and consistency in oncology care, rather than a disruptive force.
UCSF’s AI initiative marks a significant advancement in oncology by addressing the critical issues of information overload, evolving guidelines and limited specialist availability. Through intelligent automation and alignment with clinical standards, the system improves the speed and accuracy of cancer care while supporting clinician autonomy. Its success underscores the potential of AI to deliver scalable, evidence-based support in complex medical environments. For institutions looking to replicate this achievement, a strategic focus on data integration, transparency and clinician involvement will be essential. As healthcare continues to evolve, such innovations demonstrate how AI can enhance, not replace, the expertise at the heart of patient care.
