Surgical treatment plays an important role in the treatment of gastric cancer and is the main treatment currently available to achieve a cure. For cases where radical resection cannot be performed, palliative resection of the primary tumor should be attempted based on the patient's specific condition. Additionally, considering the stage of gastric cancer, the biological characteristics of the tumor, and the patient's overall health condition, treatments such as chemotherapy, radiotherapy, traditional Chinese medicine, and immunotherapy should be comprehensively considered and selected accordingly.
