AbstractGastric and esophago-gastric junction (EGJ) adenocarcinoma are leading causes of cancer mortality and morbidity worldwide. In this short update article, we outline novel key developments in this field. Molecular defined subtypes can guide treatment decisions and create a roadmap for development of future agents in distinct subgroups of gastric cancer. In locally advanced EGJ cancer chemo-radiotherapy or perioperative chemotherapy are recommended treatment strategies. The FLOT regimen has evolved as a new standard for perioperative chemotherapy due to improved survival outcomes. For gastric cancer with limited metastasis, multimodality treatment approaches are under investigation. Systemic treatment over several lines along with best supportive care represents a standard in the management of metastatic disease. First line treatment should include trastuzmab in case of Her2 positivity. Immune checkpoint inhibitors are very effective in microsatellite instable tumors even in late treatment lines. In perspective, checkpoint inhibitors hold promise to become part of the standard treatment in the near future and novel Her2 targeted treatment approaches currently under development show promising results.Thieme.
