MMCL-CDR: Enhancing Cancer Drug Response Prediction with Multi-Omics and Morphology Images Contrastive Representation Learning
Motivation Cancer is a complex disease that results in a significant number of global fatalities. Treatment strategies can vary among patients, even if they have the same type of cancer. The application of precision medicine in cancer shows promise for treating different types of cancer, reducing healthcare expenses, and improving recovery rates. To achieve personalized cancer treatment, machine learning models have been developed to predict drug responses based on tumor and drug characteristics. However, current studies either focus on constructing homogeneous networks from single data source or heterogeneous networks from multi-omics data. While multi-omics data have shown potential in predicting drug responses in cancer cell lines, there is still a lack of research that effectively utilizes insights from different modalities. Furthermore, effectively utilizing the multi-modal knowledge of cancer cell lines poses a challenge due to the heterogeneity inherent in these modalities. Results To address these challenges, we introduce MMCL-CDR, a multi-modal approach for cancer drug response prediction that integrates copy number variation, gene expression, morphology images of cell lines and chemical structure of drugs.
