Abstract:

Gastric cancer, a malignant tumor with high morbidity and mortality in China, has characteristics such as high heterogeneity and poor prognosis. With the advent of the 21st century, significant progress has been made in gastric cancer diagnosis and treatment due to the rapid development of genomics, laparoscopic minimally invasive techniques, targeted therapy and immunotherapy. This article summarized the important research progress in the field of gastric cancer prevention and treatment since the 21st century, and looked forward to the future. We hope to make greater progress and breakthroughs in early screening, diagnosis and precise treatment of gastric cancer, further improve the overall survival rate of patients, and transform gastric cancer into a controllable “chronic disease”.
