摘要

Drug combination therapy can reduce drug resistance and improve treatment efficacy, making it an increasingly promising cancer treatment method. Although existing computational methods have achieved significant success, predictions on unseen data remain a challenge. There are complex associations between drug pairs and cell lines, and existing models cannot capture more general feature interaction patterns among them, which hinders the ability of models to generalize from seen samples to unseen samples. To address this problem, we propose a dual-level feature interaction model called DualSyn to efficiently predict the synergy of drug combination therapy. This model first achieves interaction at the drug pair level through the drugs feature extraction module. We also designed two modules to further deepen the interaction at the drug pair and cell line level from two different perspectives. The high-order relation module is used to capture the high-order relationships among the three features, and the global information module focuses on preserving global information details. DualSyn not only improves the AUC by 2.15% compared with the state-of-the-art methods in the transductive task of the benchmark dataset, but also surpasses them in all four tasks under the inductive setting. Overall, DualSyn shows great potential in predicting and explaining drug synergistic therapies, providing a powerful new tool for future clinical applications.
