With the continuous increase in the incidence of tumors, standardized diagnosis and treatment have become the key to improving the survival rate and quality of life of patients. In recent years, new technologies, drugs and individualized treatment plans have been constantly emerging in the field of tumor treatment. However, there are still problems such as inconsistent diagnosis and treatment standards and insufficient multi-disciplinary collaboration in clinical practice. It is necessary to promote the standardization of diagnosis and treatment and the popularization and application of innovative achievements through academic exchanges. To further enhance the level of tumor prevention and treatment and promote the deep integration of cutting-edge concepts and local practices, the Chengdu High-tech Medical Association held the "Lung Cancer Treatment Progress Exchange Conference in the Era of Immunity 2.0" in Chengdu on September 21, 2025. This conference focuses on the latest guidelines for tumor diagnosis and treatment, the multidisciplinary team (MDT) model, precision medicine, and translational research, among other hot topics. It invites renowned experts to give special reports and share cases, aiming to build an academic exchange platform for clinicians, researchers, and medical institutions, and jointly promote the standardized development of tumor diagnosis and treatment.
