Progress in metabolic reprogramming of gastric malignant tumors to remodel tumor immune microenvironments

Metabolic reprogramming alters the processes by which tumor cells generate energy and synthesize products, affecting their growth and survival. It also reshapes the tumor microenvironment by influencing immune cell function and interaction. Current literature suggests that the metabolic characteristics of gastric malignancies are closely associated with tumor immune evasion and inflammatory responses, thereby influencing immune cell infiltration, tumor progression, and patient prognosis. Despite some progress, research on metabolic reprogramming in gastric cancer (GC) is challenging, particularly in understanding the specific mechanisms involved and their clinical applications. This review aims to comprehensively explore the mechanisms of metabolic reprogramming in GC and analyze its impact on the tumor immune microenvironment. We also propose potential metabolic-immune therapeutic strategies, such as glutaminase inhibitors, lactate transport blockers, and immune checkpoint therapy combined with metabolic regulators, providing new ideas and directions for immunotherapy in GC.
