The length of life after chemotherapy for gastric cancer is firstly determined by the specific stage of gastric cancer, if it is advanced gastric cancer, most patients will live less than 1 year after chemotherapy. If it is intermediate gastric cancer, the survival time may be relatively longer. Clinically, the overall survival rate of gastric cancer is 5 years, which is generally about 30%. In other words, only about 30 out of 100 people can survive beyond 5 years. Therefore, after chemotherapy for gastric cancer, it needs further regular outpatient follow-up and regular checkups, and other adjuvant medications may be needed after chemotherapy. Therefore, there is no clear answer on the specific time of survival after chemotherapy for gastric cancer.
