讲座摘要
Glioblastoma Multiforme (GBM), a World Health Organization (WHO) grade IV tumor, is the most common primary malignant brain cancer with median overall survival (OS) of 15 months despite best available treatments. Although one- and three-year OS rates are 39.7% and 10.1%, respectively, it is of note that some patients do significantly better than others. The classification of Glioma based on genomic features is integral to the WHO classification and has shown strong prognostic value independent of age and histology. Despite molecular advancements, the recurrent and molecularly heterogeneous nature of GBM garners its resilience. The tumor cells and tumor microenvironment rapidly adapt to treatment and there is not an available method for continuous monitoring of such adaptive changes at a molecular level. Clinical care for patients with GBM is primed for advancement through the use of neural networks that augment imaging and genomic analysis and predict progression-free (PFS) and OS. Such applications can also be applied to therapeutic navigation and discovery.
Integrating molecular biomarkers with multiparametric MRI (mpMRI) features in a multiplex setting has an enormous potential to identify GBM biomarkers crucial for: 1) improving patient risk stratification, 2) developing precision treatment and 3) predicting outcome of salvage treatment. We aim to improve GBM treatment effectiveness by 1) developing machine learning models to segment intratumor sub-regions on mpMRI and identifying prognostic imaging features prior to surgical intervention, 2) developing pathway associated neural network models for prognosis by integrating gene expression patterns, oncogenic pathways and imaging features.
