Among 32 studies, Random forest and XGBoost were the most common AI/ML models (n=17 each) for predicting cardiovascular adverse events in cancer patients, though limited by methodological flaws.
Systematic Review (n=32)
Do AI/ML models accurately predict cardiovascular adverse events in patients with cancer?
AI/ML models show promise for predicting cardiovascular adverse events in cancer patients, but their clinical applicability is currently limited by methodological shortcomings such as insufficient preprocessing transparency and lack of external validation.
INTRODUCTION: Cardiovascular (CV) adverse events are increasingly recognized in patients with cancer. Previous reviews of AI/ML have focused on single cancer types, imaging-based data, and lacked evaluation of methodological rigor. This systematic review synthesized AI/ML models developed to predict CV adverse events from patient-level clinical data across diverse cancer populations. METHODS: This review followed the PRISMA 2020 guidelines. PubMed and Web of Science were searched through 26 October 2025. Study characteristics, model development, and handling of features and missing data were extracted. Study quality was assessed using the IJMEDI checklist. RESULTS: Of 32 included studies, 18 compared multiple algorithms and 14 used a single algorithm. Random forest and XGBoost were the most common methods (n = 17, respectively), and XGBoost was most often the best-performing model in multi-algorithm studies, although substantial study heterogeneity precludes concluding general algorithmic superiority. Common limitations were unreported missing data handling (n = 17), limited external validation (n = 8), and rare calibration assessment (n = 4). Most studies were rated medium quality (n = 28). CONCLUSIONS: AI/ML models show promise for predicting CV adverse events in patients with cancer; however, clinical applicability is constrained by insufficient preprocessing transparency, limited external validation, and inadequate calibration reporting.
Wu et al. (Fri,) conducted a systematic review in Cardiovascular adverse events in patients with cancer (n=32). AI/ML models was evaluated on Prediction of cardiovascular adverse events. Among 32 studies, Random forest and XGBoost were the most common AI/ML models (n=17 each) for predicting cardiovascular adverse events in cancer patients, though limited by methodological flaws.
