of reviewed studies utilized Data Augmentation. This represents a significant gap in mitigating overfitting and enhancing model robustness.
| ML Generation | Prevalence | Average Accuracy | Description |
|---|---|---|---|
| Traditional ML | 37.5% (12 studies) | 87.23% | Well-understood algorithms (SVM, DT, ANN), often require manual feature engineering. |
| Modern ML (Deep Learning) | 21.87% (7 studies) | 88.72% | Leverages deep neural networks (CNNs, LSTMs), automates feature extraction. |
| Hybrid ML | 40.62% (13 studies) | 91.73% | Combines traditional and modern techniques to capitalize on complementary strengths, offering enhanced performance and interpretability. |
Key Findings in BC Survival Prediction
The research uncovered several critical insights regarding the performance and characteristics of AI models in predicting breast cancer survival, guiding future development strategies.
97.95%
Peak average accuracy achieved by models predicting breast cancer survival over a 10-year window.
Validation Approach: The Internal Validation Predominance
The study found that 81.25% of reviewed studies relied solely on internal validation, primarily using K-fold cross-validation or train/test split strategies. While convenient, this heavy reliance on internal validation raises concerns about the generalizability and robustness of the models when applied to diverse, real-world clinical populations. For enterprise deployment, rigorous external validation on independent datasets is crucial to ensure reliability and trust in AI-driven diagnostic tools.
| Dataset Type | Prevalence | Average Accuracy | Implication |
|---|---|---|---|
| Private Datasets | 56.25% (18 studies) | 89.42% | Predominant choice, but may limit generalizability without robust external validation. |
| Public Datasets (TCGA, METABRIC, SEER) | 34.37% (11 studies) | 89.80% | Valuable resources, but often smaller proportion of studies. |
| Combination (Public + Private) | 9.37% (3 studies) | 93.10% | Achieved highest average accuracy, suggesting benefit of diverse data sources. |
Identified Challenges in AI for BC Prediction
Despite promising results, several challenges impede the widespread clinical adoption and full potential realization of AI in breast cancer survival prediction.

of reviewed studies implemented data augmentation techniques, missing a key opportunity to improve model generalization and mitigate overfitting.
The Interpretability vs. Accuracy Trade-off
Deep Learning (DL) models, particularly CNNs, often achieve superior accuracy by autonomously extracting complex features, but they frequently operate as "black boxes." This lack of interpretability poses a significant drawback in clinical settings where understanding the rationale behind a prediction is crucial for trust and liability. In contrast, traditional ML methods are more interpretable but may lack DL's accuracy in complex tasks. Bridging this gap with Explainable AI (XAI) is essential for clinical confidence and regulatory compliance.

of studies relied on internal validation, indicating a critical need for more external validation to ensure real-world applicability and generalizability.
Strategic Future Directions for AI in BC Prediction
To maximize the clinical utility and impact of AI in breast cancer survival prediction, future research and development should focus on these strategic areas.
Hybrid Models for Enhanced Robustness and Interpretability
The analysis indicates that hybrid models, which strategically combine traditional ML and deep learning techniques, achieve the highest average accuracy (91.73%). These models can leverage DL for sophisticated feature extraction while utilizing traditional ML for classification, offering both enhanced performance and crucial interpretability. Enterprises should prioritize developing and deploying such integrated frameworks to navigate complex clinical scenarios effectively.

of prediction yielded the highest average accuracy (97.95%), suggesting a strong benefit in exploring longer prediction horizons for AI models.
Prioritizing Explainable AI (XAI) for Clinical Adoption
To overcome the "black box" nature of advanced AI models and foster clinical trust, future research must emphasize the development and integration of Explainable AI techniques like SHAP and LIME. These methods provide transparency into model decision-making, which is indispensable for clinical validation, ethical deployment, and regulatory acceptance, paving the way for AI's seamless integration into patient care workflows.
