The survival of patients with gastric cancer depends mainly on the degree of differentiation of the tumor, the pathological stage of the tumor, and the effectiveness of treatment.
Gastric cancer is a very common type of gastrointestinal malignancy in clinical practice.
In early stage gastric cancer, the lesion is confined to the mucosa and the patient can survive for a long time, but once gastric cancer is detected, it is often in the progressive stage. The average survival period for progressive gastric cancer, without any treatment, is about one year from the onset of symptoms to death. If treated surgically, the five-year survival rates for stage I, II, and III gastric cancer are 70-80%, 40-50%, and 35%, respectively, while the five-year survival rate for patients with stage IV gastric cancer is less than 10%.
