The survival time after surgery for advanced gastric cancer is different. After surgery for advanced gastric cancer, the survival time may be shorter, about 1 year overall. If the patient’s disease progresses very fast, it may take about six months. If the patient’s disease progresses slowly, the tumor recurrence and metastasis are slow, and the patient’s nutritional support is relatively good, the survival time may be extended, including 1.5-2 years. However, for mid-stage gastric cancer, the prognosis is relatively better, and the 5-year survival rate can reach more than 50%, that is, half of the patients can live up to 5 years or even more after surgery, but they should come to the hospital for regular checkups, that is, follow-up. However, patients should come to the hospital for regular checkups, i.e., follow up. They also need to finish the course of chemotherapy, review gastroscopy and abdominopelvic enhancement CT every year, as well as review tumor indicators.
