The "Sichuan-Chongqing Digestive Tract Tumor Immunotherapy Salon" hosted by the Chengdu High-tech Medical Association is scheduled to be held online on August 13, 2025. The conference adheres to the concept of "standardized and reasonable" diagnosis and treatment of digestive tract tumors. At that time, professors from both within and outside the province will be invited to think about how immunotherapy has profoundly changed the landscape of tumor treatment, bringing longer survival periods to patients and providing more treatment options for clinicians. This time, in-depth discussions will be held on the efficacy and safety of immunotherapy. Promote the standardization level of digestive tract tumors in the Sichuan-Chongqing region.
