Precision Forecasting in Colorectal Oncology: Predicting Six-Month Survival to Optimize Clinical Decisions

Electronics, Год журнала: 2025, Номер 14(5), С. 880 - 880

Опубликована: Фев. 23, 2025

Colorectal cancer (CRC) has a relatively high five-year survival rate compared to other cancers; however, this drops significantly in patients with malignant CRC. One critical factor palliative care decision-making is the ability accurately predict patient survival, six-month period commonly used as threshold. In study, we evaluated performance of five machine learning models—logistic regression, decision tree, random forest, multilayer perceptron, and extreme gradient boosting (XGBoost)—in predicting for CRC using publicly available synthetic dataset containing 11,774 samples 51 features. The models were trained validated five-fold cross-validation, minority oversampling technique (SMOTE) was applied address class imbalance. Among models, XGBoost demonstrated highest performance, achieving 95% accuracy, precision, recall, F1-score, along 90% specificity. Feature importance analysis identified smoking status surgical history key factors influencing model predictions. These findings highlight potential tree-based supporting timely informed decisions, while also providing insights into handling data imbalance optimizing parameters prediction tasks.

Machine Learning to Evaluate the Effects of Non-Clinical Social Determinant Features in Predicting Colorectal Cancer Mortality in a Medically Underserved Appalachian Population

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Фев. 6, 2025

Colorectal cancer (CRC) is the 2nd leading cause of death in United States (US). Rural Appalachia suffers highest CRC incidence and mortality rates. There are several non-clinical health-related social determinant factors (SDOH) associated with mortality. This study describes novel predictive modeling that uses demographic, clinical, SDOH features from health records data Appalachian community centers to predict 5-year survival. We trained, validated, tested four gradient-boosted tree ensemble (XGBoost) machine learning models which were developed using selected combinations available features. The area under receiver operating characteristic curve was greatest model included demographic clinical (0.79; P < 0.0001). Feature stratification showed rurality as top feature. It demonstrated ML performs better when included, significantly impacts survival Appalachia.

Colorectal cancer liver metastasis (CRLM) is a significant contributor to cancer-related illness and death. Neoadjuvant chemotherapy (NAC) an essential treatment approach; however, optimal patient selection remains challenge. This study aimed develop machine learning-based predictive model using hematological biomarkers assess the efficacy of NAC in patients with CRLM. We retrospectively analyzed clinical data 214 CRLM treated XELOX regimen. Blood characteristics before after NAC, as well ratios these biomarkers, were integrated into learning models. Logistic regression, decision trees (DTs), random forest (RF), support vector (SVM), AdaBoost used for modeling. The performance models was evaluated AUROC, F1-score, external validation. DT (AUROC: 0.915, F1-score: 0.621) RF 0.999, 0.857) demonstrated best training cohort. incorporating ratio post-treatment pre-treatment gamma-glutamyl transferase (rGGT) carcinoembryonic antigen (rCEA) formed GCR index, which achieved AUROC 0.853 index showed strong relevance, predicting better responses lower rCEA higher rGGT levels. serves biomarker CRLM, providing valuable reference prognostic assessment patients.
