Core Tip

Core tip: Gastric cancer (GC) still represents a leading cause of cancer related morbidity and mortality worldwide accounting for more than 1 million of newly diagnosed cases and thousands of deaths every year. In the last decade, global efforts have been undertaken to investigate in detail the genomic and epigenomic heterogeneity of this disease, resulting in innovative molecular classifications of GC based on gene expression profiling and in the identification of new specific and sensitive predictive and prognostic biomarkers. At the same time, the development of targeted therapies has expanded the treatment scenario for advanced GC. The aim of the present manuscript is to provide a detailed and comprehensive overview of the recent molecular classifications from The Cancer Genome Atlas and the Asian Cancer Research Group and to present key promising developments in the field of immunotherapy and targeted therapies in metastatic GC.
