This research aims to enhance early detection of ovarian cancer using high-dimensional proteomic data and advanced machine learning approaches.
Utilized longitudinal pre-diagnostic serum samples from the UKCTOCS cohort.
Profiled eight candidate ovarian cancer biomarkers and additional cancer-associated proteins.
Employed Synolitic Graph Neural Network framework to analyze high-dimensional data.
Compared GNN performance to conventional machine learning models using ROC-AUC metrics.
Conventional models achieved high discriminative performance with XGBoost ROC-AUC of 92% within one year of diagnosis.
GNNs maintained robust early detection capability with ROC-AUC ~74% in the 1–2 year window.
Results indicate GNNs are effective in detecting subtle molecular changes prior to clinical diagnosis.
