📚 Background
The use of immune checkpoint inhibitors (ICIs) has revolutionized the treatment landscape for various cancers, including hepatitis B virus (HBV)-positive hepatocellular carcinoma. However, the emergence of immune-related adverse events (irAEs) poses significant challenges, necessitating the development of predictive models to identify patients at risk and optimize treatment strategies.
🗒️ Study
This study, conducted at Henan Cancer Hospital, involved a retrospective analysis of data from 274 patients diagnosed with HBV-related liver cancer who received treatment with PD-1 and/or CTLA4 inhibitors. Researchers constructed predictive models using various machine learning techniques, including Lasso, Random Forest, and XGBoost, to analyze clinical characteristics and immune cell data.
📈 Results
The study revealed that the Random Forest model achieved the highest accuracy of 0.961, while XGBoost and Lasso models also demonstrated strong performance with accuracies of 0.903 and 0.864, respectively. Notably, the analysis indicated that antiviral therapy significantly reduced the incidence of irAEs and was correlated with the severity of these events.
🌍 Impact and Implications
The findings from this study underscore the importance of integrating antiviral therapy into treatment regimens for patients with HBV-positive hepatocellular carcinoma receiving ICIs. By effectively managing viral load, healthcare providers can potentially enhance patient outcomes and reduce the burden of irAEs, paving the way for more personalized and safer immunotherapy approaches.
🔮 Conclusion
This research highlights the promising role of antiviral therapy in mitigating irAEs among patients treated with ICIs for HBV-related liver cancer. The application of machine learning models not only aids in predicting adverse events but also emphasizes the need for continuous antiviral treatment to improve patient safety and treatment efficacy. Future studies should further explore these relationships to refine therapeutic strategies.

Antiviral therapy can effectively suppress irAEs in HBV positive hepatocellular carcinoma treated with ICIs: validation based on multi machine learning.
Abstract
BACKGROUND: Immune checkpoint inhibitors have proven efficacy against hepatitis B-virus positive hepatocellular. However, Immunotherapy-related adverse reactions are still a major challenge faced by tumor immunotherapy, so it is urgent to establish new methods to effectively predict immunotherapy-related adverse reactions.
OBJECTIVE: Multi-machine learning model were constructed to screen the risk factors for irAEs in ICIs for the treatment of HBV-related hepatocellular and build a prediction model for the occurrence of clinical IRAEs.
METHODS: Data from 274 hepatitis B virus positive tumor patients who received PD-1 or/and CTLA4 inhibitor treatment and had immune cell detection results were collected from Henan Cancer Hospital for retrospective analysis. Models were established using Lasso, RSF (RandomForest), and xgBoost, with ten-fold cross-validation and resampling methods used to ensure model reliability. The impact of influencing factors on irAEs (immune-related adverse events) was validated using Decision Curve Analysis (DCA). Both uni/multivariable analysis were accomplished by Chi-square/Fisher’s exact tests. The accuracy of the model is verified in the DCA curve.
RESULTS: A total of 274 HBV-related liver cancer patients were enrolled in the study. Predictive models were constructed using three machine learning algorithms to analyze and statistically evaluate clinical characteristics, including immune cell data. The accuracy of the Lasso regression model was 0.864, XGBoost achieved 0.903, and RandomForest reached 0.961. Resampling internal validation revealed that RandomForest had the highest recall rate (AUC = 0.892). Based on machine learning-selected indicators, antiviral therapy and The HBV DNA copy number showed a significant correlation with both the occurrence and severity of irAEs. Antiviral therapy notably reduced the incidence of IRAEs and may modulate these events through regulation of B cells. The DCA model also demonstrated strong predictive performance. Effective control of viral load through antiviral therapy significantly mitigates the occurrence of irAEs.
CONCLUSION: ICIs show therapeutic potential in the treatment of HBV-HCC. Following antiviral therapy, the incidence of severe irAEs decreases. Even in cases where viral load control is incomplete, continuous antiviral treatment can still mitigate the occurrence of irAEs.
