Survival period of residual stomach cancer is affected by many factors, early survival period is longer, but late survival period will be shorter, in addition, it is also affected by each person’s physique. After comprehensive treatment, early gastric cancer can survive for more than 5-10 years, but if metastasis has already appeared and it is advanced gastric cancer, the survival period may only be one year or half a year, or even only a few months in some cases. Therefore, it is necessary to actively treat and observe it. If the residual stomach cancer reaches the advanced stage, the patient can also consider chemotherapy, targeted therapy or bio-immunotherapy if the patient’s body allows it. A considerable part of patients will prolong the survival period and improve the quality of life.
