Speakers in the basic research session brought a number of wonderful reports, including “Multiple recombinant analysis of new antigens and immune microenvironment in precision immunotherapy for colon cancer”, “Screening and prevention of gastric cancer in high risk populations in our country”, “The molecular epidemiology of malignant tumors in the Chinese population”, “The promotion of artificial intelligence in the transformation of basic research results to clinical”, “The histogenesis mechanism of the JC virus T antigen on gastric cancer”, “The possibility of autophagy in the precise treatment of tumors”, “Research progress of esophagus-gastric junction adenocarcinoma”.
The content of the nursing session include “Continuous management practice of cancer patients under the concept of accelerated recovery”, “Predictive evaluation of critically ill patients in surgery”, “Evidence-based continuous quality improvement case sharing”, “Multidisciplinary diagnosis and treatment mode of cancer surgery specialized care management and practice”, “Application of minimally invasive surgery for gastric cancer”, and “Full-process management of gastric cancer during perioperative period”.
The inauguration meeting of the Gastric Tumor Professional Committee of Zhejiang Anticancer Association was held. The meeting invited Professor Zhu Guanbao, Professor Hu Ping, Professor Xu Hongbao, and Professor Jin Huicheng as advisory members, and Professor Cheng Xiangdong was elected as the chairman, and Professor Wu Dan, Professor Wang Xianfa, Professor Shen Xian, Professor Chen Ping, Professor Tao Feng, and Professor Ying Jie'er were the vice-chairmen.
