Ovarian Cancer Detection Using Adaptive Contextual Propagation Deep Graph Neural Network with Migrating Walrus Algorithm
摘要
Ovarian cancer (OC) remains one of the most fatal malignancies among women worldwide, with epithelial ovarian cancer (EOC) being particularly difficult to diagnose due to complex tumor morphology, low tissue contrast in histopathology images, and noise corruption. Conventional diagnostic approaches suffer from poor feature representation, inaccurate segmentation, and weak generalization, leading to reduced classification accuracy.
MethodsWe propose an adaptive contextual propagation deep graph neural network optimized with the migrating walrus algorithm (ACPDGNNet-MWA). The pipeline integrates multiple stages: (i) image enhancement through an observability-constrained resampling-free cubature kalman filter (O-CRCKF) for noise reduction, (ii) accurate segmentation via a prompt-tuned multi-task taxonomic transformer (PTMT-TT), (iii) robust feature extraction using enhanced VGG19 (E-VGG19), and (iv) efficient classification through ACPDGNNet, which combines a contextual attention network (CAN) with an adaptive propagation deep graph neural network (AP-DGNN). Model parameters are further optimized with MWA to enhance convergence and generalization.
ResultsExtensive experiments on the EOC histopathology dataset demonstrated the superiority of the proposed method, achieving 99.9% accuracy, 99.8% precision, 99.7% sensitivity, and a dice similarity coefficient (DSC) of 99.6%, surpassing state-of-the-art benchmarks.
ConclusionThe ACPDGNNet-MWA framework provides a highly accurate and computationally efficient approach for EOC detection, offering substantial potential for clinical decision support in ovarian cancer diagnosis.
