Overall, the 5-year survival rate of gastric cancer is about 50%, which means half of the patients can live up to 5 years or even more after surgery. However, for early gastric cancer, the survival rate is higher, reaching more than 90%, that is, more than 90% of patients can live up to 5 years or even longer after surgery, which basically can achieve clinical cure. Early stage gastric cancer usually has small lesions and no lymph node metastasis, but there may be lymph node metastasis, so regular follow-up after surgery and regular review is possible. However, if it is advanced gastric cancer, the survival rate is lower. Advanced gastric cancer means that the tumor is large or has distant metastasis, including liver metastasis and peritoneal implant metastasis, etc. The tumor progresses very fast, and the patient will soon develop cachexia, and the overall survival period is about 1 year.
