How many years of life expectancy after early resection of gastric cancer cannot be generalized, the specific survival time is related to the pathological stage, treatment measures, physical condition and other factors. The survival time of most patients ranges from about 5 years to decades. Early stage gastric cancer, due to early detection and treatment, can have many tumor treatment options to choose from, the 5-year survival rate is very high, and the prognosis of patients is usually good. The 5-year survival rate for patients with Stage I gastric cancer is generally 80% to 90%, Stage II is about 50%, Stage III is 15% to 30%, and it is only 2% when it reaches Stage IV. Generally speaking, the earlier the detection and the earlier the treatment, the better the therapeutic effect, so it is recommended that patients seek medical treatment as early as possible. After gastric cancer surgery, it is imperative to have regular review to keep track of one’s condition, so as to minimize recurrence or early detection of recurrence and metastasis, and to prolong the survival period, in order to live longer after gastric cancer surgery.
