AI ANALYSIS REPORT
CanRisk-DB: an artificial intelligence-driven comprehensive database of cancer risk factors
CanRisk-DB addresses the fragmentation of cancer risk factor research by leveraging a multi-stage AI pipeline (PICOS, GRAG) to systematically aggregate and standardize evidence. It analyzed 435,975 publications, compiling 445,646 records across 76 risk factor groups and 42 cancer types from 80 countries. The AI system demonstrated high accuracy (99.4% sensitivity for abstract screening) and exceptional efficiency (0.4s per abstract vs. 39.8s manually). This resource serves as a comprehensive knowledge base, supporting advanced etiological research, risk analyses, and the development of evidence-informed cancer prevention strategies.

CanRisk-DB stands as the most comprehensive database of cancer-risk associations to date, systematically aggregating and standardizing risk factor data from the global literature. It covers 42 classified cancer types and 76 risk factor groups across 80 countries, spanning over five decades of research. This extensive coverage provides an unparalleled resource for understanding cancer etiology.
Key features include its ability to convert unstructured textual data into structured, analyzable formats, facilitating high-throughput meta-analyses, integrative risk assessments, and temporal trend analyses. The platform is designed for user-driven data retrieval based on cancer types and risk factors, enhancing in-depth data mining and knowledge discovery.
The core of CanRisk-DB is an advanced multi-stage AI pipeline based on the PICOS (Population, Intervention, Comparison, Outcome, Study Design) framework. This pipeline meticulously processes biomedical literature from PubMed, Embase, and Cochrane databases.
A critical component is the Graph-based Retrieval-Augmented Generation (GRAG) framework, which extracts precise information on cancer types, risk factors, and quantitative estimates (e.g., relative risk [RR], hazard ratio [HR], standardized incidence ratio [SIR]). The system utilizes a multimodal approach to parse full texts, including text, charts, and formulas, and employs a voting mechanism with large language models (LLMs) for efficient literature filtering.
CanRisk-DB's AI system demonstrated superior efficiency and high accuracy compared to manual human researchers. In abstract screening, AI achieved 99.4% sensitivity and 97.0% specificity, processing abstracts at an average of 0.4 seconds (compared to 39.8 seconds for humans).
For full-text screening, AI maintained 98.8% sensitivity and 99.4% cumulative specificity, completing tasks in 1.5 seconds per full text (versus 131.7 seconds for humans). Data extraction precision for effect size and cohort information stood at 95.6% and 96.3% respectively, with sensitivities of 88.3% and 99.6%. These results underscore the transformative potential of AI in biomedical literature synthesis.
CanRisk-DB provides a foundational framework for generating hypotheses that could inform future cancer prevention strategies. It supports evidence-based etiological research, advanced risk analyses, and the development of targeted prevention strategies.
Epidemiologists can leverage standardized effect estimates for meta-analyses, while public health researchers can identify high-risk populations for screening programs. The database also serves as a valuable guide for mapping the research landscape, identifying well-studied versus underexplored risk factors, and offering a robust foundation for systematic reviews and meta-analyses, ultimately helping to mitigate the global burden of cancer.

Case Study: Oropharyngeal Cancer Risk Factors
CanRisk-DB was used to identify risk factors for oropharyngeal cancer. It successfully identified key associations like tobacco use (RR=13.30), history of CIN3 (RR=5.50), and alcohol consumption (RR=5.02). Crucially, the platform recovered 27% more relevant studies than conventional keyword-based searches, including studies from broader head and neck cancer analyses, demonstrating its ability to uncover overlooked literature.
Key Findings:
- Tobacco use (RR=13.30), CIN3 history (RR=5.50), and alcohol consumption (RR=5.02) were primary risk factors.
- Identified 27% more relevant studies than traditional search methods.
- Demonstrated capability to retrieve studies from broader analyses, enhancing comprehensiveness.
Impact: Improves comprehensive understanding of specific cancer etiologies by integrating diverse study contexts, leading to more robust risk assessment models.
