The recurrence time of early gastric cancer after surgery is not specific in terms of years, but indirectly reflected by the probability of survival, generally the recurrence rate is <10% within 5 years. After surgical treatment for early gastric cancer, the prognosis is good, and most patients can survive for more than 5 years, with 5-year survival rate >90%, because patients’ recurrence is mostly in advanced stage of gastric cancer, which is difficult to be cured radically and will greatly shorten the survival time of patients, so the recurrence rate can be indirectly expressed by 5-year survival rate, i.e., the recurrence rate is <10% in 5 years. Gastric cancer has various pathologic types, and the degree of malignancy varies greatly. For example, imprinted cell carcinoma has high malignancy and may develop distant metastasis at early stage, with high recurrence rate; while papillary adenocarcinoma has lower malignancy, low postoperative recurrence rate and high 5-year survival rate. After early gastric cancer surgery, patients need to go to the hospital for rechecking regularly to determine whether there is recurrence or not. Generally, the rechecking will be done once every 3 months in the first 2 years after surgery, and once every 6 months starting from the third year after surgery. Review items include gastroscopy, tumor markers and abdominal CT and other related examinations. Patients are advised to maintain good living habits, regular routine and regular follow-up, and if recurrence occurs, early treatment is needed to prolong survival.
