If gastric cancer spreads to abdominal lymph nodes or systemic lymph node metastasis in late stage, the survival period is relatively short, and from clinical research or experience, the survival rate of gastric cancer in late stage is only 3-6 months. However, no matter which treatment plan and treatment measures are adopted, the survival period of patients with middle and late stage gastric cancer, especially those who have spread to lymph nodes or metastasis to multiple organs of the body, may not be particularly long.
