The recurrence rate of early gastric cancer after surgery is very low, with a 5-year survival rate of more than 90%, which means that the recurrence rate is basically less than 10% within 5 years. If patients can follow up regularly, have gastroscopy in the hospital every year, and have checkups in the hospital every 3 months in the first 2 years and every 6 months in the last 3 years, including checking tumor indexes or CT of the abdomen and pelvis, as well as blood routine, liver and kidney functions and other related indexes, then it is very difficult to have recurrence, and basically, it can be clinically cured. If anastomotic recurrence or lymph node metastasis is detected during the examination in the hospital, timely intervention, timely surgery, including timely chemotherapy, will have a very good effect and usually prolong the overall survival time of the patient.
