Core Tip
Core Tip: The nervous system plays a critical but underrecognized role in gastric cancer (GC) progression through bidirectional neuro-tumoral interactions. Neurotransmitters—including norepinephrine, acetylcholine, glutamate, γ-aminobutyric acid, adenosine, and neuropeptide Y—produced by both neurons and malignant cells, actively reprogram the tumor microenvironment. These mediators regulate proliferation, invasion, metastasis, immune evasion, and therapeutic resistance in GC. This review highlights advances in understanding neurotransmitter-driven mechanisms and introduces the concept of “neuro-gastric oncology”, providing a rationale for novel therapeutic strategies targeting neuro-tumoral signaling pathways.
