Assessment of Synthetic Data Utilization for Creating Survival Prediction Models in Colorectal Cancer: External Validation of Sophisticated Machine Learning Approaches Using National Cancer Data Center Information
To evaluate the clinical applicability of predictive models based on synthetic data in real healthcare settings.
Approach:
Data Processing: Categorical variables were one-hot encoded, and missing values were handled through complete case analysis.
Key Findings:
Synthetic data can replicate statistical properties of real clinical data.
Domain adaptation can mitigate performance degradation due to domain shifts between synthetic and real data.
Interpretation:
The study quantitatively evaluated the effectiveness of models pretrained on synthetic data when applied to actual hospital data, using metrics such as accuracy and AUC.
Limitations:
Limited studies have validated predictive models using synthetic data on real medical data, particularly in diverse patient populations.
Domain shifts may occur due to differences in patient characteristics and treatment patterns, affecting model performance.
Conclusion:
The study highlights the potential of synthetic data in developing predictive models for colorectal cancer survival, indicating the necessity for further validation in diverse clinical settings.
