Usually, the survival time of postoperative recurrence of gastric cancer has a great relationship with the size and location of the patient’s tumor recurrence, treatment effect, treatment method, his/her own physical condition, mood, etc., and there is no clear time. There is no definite time. The patient may survive for a long time, only three to six months, or one to two years, which are analyzed as follows: 1. If the recurrence is only localized and the tumor is relatively small, the survival time may be longer, and the growth of the tumor can be controlled by standardized treatment, or the second surgical treatment can be considered to achieve long-term survival. 2. Most of the postoperative recurrence of stomach cancer is usually more serious and can not be treated by further surgery. If the treatment is not timely, it may cause the survival time of the patient to be reduced, and the patient can survive for 3 to 6 months. 3. After recurrence of gastric cancer, if patients are actively treated by chemotherapy, radiotherapy, or given targeted drug therapy or immunotherapy, the survival time of patients is about 6 months to 1 year, and some patients are sensitive to targeted drugs and immunotherapy, and the survival time can be prolonged. Patients with postoperative recurrence of gastric cancer should adjust their mindset, keep a good mood, face treatment with positive and optimistic attitude, and exercise properly to strengthen immunity. Patients with postoperative recurrence of gastric cancer need to go to hospital for treatment under doctor’s guidance.
