Superior Predictive Power
Our stacking ensemble model achieved an AUROC of 0.9949, setting a new benchmark for GBC survival prediction. This model consistently outperformed all baseline models (Logistic Regression, SVM, Random Forest, etc.) and demonstrated superior calibration. This robust performance is critical for reliable clinical application.
We rigorously evaluated various machine learning models including Logistic Regression, Decision Tree, SVM, Random Forest, K-Nearest Neighbors (KNN), AdaBoost, CatBoost, XGBoost, Gradient Boosting, and LightGBM. The stacking ensemble, combining the strengths of multiple base models, proved to be the most accurate and stable. This approach leverages collective strengths and minimizes individual weaknesses, leading to highly dependable predictions for unseen clinical cases. Evaluation metrics such as precision, recall, F1 score, and ROC-AUC curve confirmed the superior discrimination and calibration of the stacking model.
Transparent & Interpretable AI
We implemented a multi-layer explainability framework using SHAP, PDPs, ICE, and LIME to interpret model predictions at both global and individual patient levels. This enhances clinical trustworthiness and usability, moving beyond basic feature importance to uncover complex relationships.
SHAP (SHapley Additive exPlanations) values were used to quantify the contribution of each feature to a specific prediction, providing insights into factors like tumor stage, metastasis, and liver enzymes. Partial Dependence Plots (PDPs) visualized the marginal effect of individual clinical characteristics on predicted mortality, averaging the influence of other covariates. Individual Conditional Expectation (ICE) plots revealed individualized effects, showing how predicted mortality changes when a single attribute varies, while others remain fixed. Local Interpretable Model-agnostic Explanations (LIME) provided case-specific feature attribution, explaining individual patient predictions by building linear surrogate models in their local neighborhood.
Critical Prognostic Indicators
Analysis revealed elevated liver enzymes (AST, ALT, ALP, GGT) and bilirubin levels as significant prognostic factors. Advanced age is also correlated with terminal disease outcomes. Tumor stage (especially Stage IV), absence of surgery, and the presence of metastasis were identified as top negative prognostic indicators by SHAP.
Other critical factors include serum albumin levels, which showed an inverse association with predicted mortality, reinforcing its importance in assessing nutritional and systemic inflammatory status. The study also highlighted the prevalence of adenocarcinoma, advanced tumor stages and grades, and the liver as a common metastatic site in cases with poor outcomes. Comorbidities like diabetes and hypertension were also found to be associated with GBC, with renal impairment and poor glucose control linked to adverse outcomes.

Case Study: Personalized Prognosis
A 70-year-old patient diagnosed with Stage IV GBC presented with elevated Gamma-glutamyl-transferase (768.00) and was undergoing disease control treatment. Our LIME explanation for this specific instance predicted a high probability of mortality (0.8437, class 0). The model highlighted that the extremely high GGT levels and the advanced tumor stage were the primary drivers for this prognosis, while the ongoing disease control treatment slightly offset the risk. This granular, patient-specific insight allows clinicians to understand why a particular prognosis is given, facilitating personalized care strategies. The model's ability to pinpoint the most influential factors for an individual patient, rather than just providing a generic outcome, significantly enhances clinical decision-making.
- Gamma-glutamyl-transferase: 768.00 (High influence on predicted mortality)
- Tumour stage_Stage IV: Present (Strong negative prognostic factor)
- Treatment administered_Disease Control: 1.00 (Positive influence, mitigating risk slightly)
