Abstract | ||||
The research compares the survival performance of hybrid survival models that merge traditional statistical techniques with machine learning to forecast survival outcomes in lung cancer patients. The study compares a group of 165 patients from Tanta Oncology Institute and Kafr El-Sheikh Chest Hospital between 2020 and 2024 by contrasting individual models—Cox Regression, Logistic Regression, and Support Vector Machines (SVM)—with two hybrid models: Cox-SVM and Logistic-SVM. High-risk predictors such as smoking, occupation, age, treatment modalities, COVID-19 infection, and disease stage were found and modeled through Kaplan-Meier analysis for feature selection. The results show that the Cox-SVM hybrid model gives the best results among all the other models with a classification accuracy of 94.5%, sensitivity of 90%, specificity of 96%, and misclassification rate of 5.45%. The Logistic-SVM hybrid then comes into play with a 90.91% accuracy, and then the individual models (Cox: 80.6%, Logistic: 67.88%, SVM: 81.8%). Hybrid model performance is because Cox's hazard-based model combines SVM's capability to work with non-linear relationships and produce better predictive accuracy and clinical relevance. Despite small sample size limitations and omission of certain variables, these results suggest that hybrid approaches in survival analysis are a valuable resource in personalized medicine. These models must be validated with larger, more diverse datasets and other prognostic factors in future research | ||||
