ObjectiveTo understand the latest research progress in the treatment of advanced gastric cancer (AGC) and explore the optimal treatment strategy. Method The latest literature on the treatment of AGC was retrieved and reviewed. Results For patients with AGC, chemotherapy, radiotherapy, targeted therapy, immunotherapy, palliative therapy, nutritional support, and traditional Chinese medicine therapy were currently adopted in clinic, the combination of them were used usually. Some patients obtained good therapeutic effects by new chemotherapy drugs and antibody conjugated drugs. In the era of first-line immunotherapy or targeted therapy, first-line immunotherapy alone, immunotherapy in combination with chemotherapy, double immunotherapy, and immunotherapy combined with anti-angiogenesis targeted drugs for AGC had represented some survival benefits. ConclusionsThe research, development, and widespread application of new anti-tumor drugs have continuously expanded the treatment methods for AGC. The development of tumor molecular biology provides an opportunity for the treatment of AGC, and the precise diagnosis and treatment pattern guided by molecular typing is gradually maturing. However, the treatment of AGC is still facing challenges. In the era of precision medicine, facing the higher heterogeneity of gastric cancer, the dilemma of precise treatment of drugs for AGC, and the research and development of new anti-tumor drugs, the optimal treatment mode of AGC still needs more clinical exploration. It is necessary to comprehensively consider various aspects such as the patient’s physical condition, previous treatment status, and drug accessibility.
