Abstract
Gastric cancer is one of the most common malignancies of the digestive system, and the number of deaths continues to increase. The standardized management of the diagnosis and treatment of gastric cancer is challenging due to the great differences in the diagnosis and treatment of gastric cancer in different regions. The Gastric Cancer Expert Committee of the National Cancer Quality Control Center (NCQCC) identified a lack of authoritative quality control standards as an opportunity to utilize its multidisciplinary membership to improve the standardized diagnosis and treatment of gastric cancer. The Gastric Cancer Expert Committee of the NCQCC aims to promote quality control and national standardization, uniformity, and normalization of gastric cancer diagnosis and treatment, which ultimately improved the survival rate and quality of life of gastric cancer patients. A panel of experts with gastrointestinal cancer surgery, gastrointestinal cancer medicine, medical imaging, pathology and radiotherapy were drawn together and determined the quality control standards for the standardized diagnosis and treatment of gastric cancer. The authors then utilized a modified Delphi approach to generate consensus recommendations.
