Five-Year CheckMate 649 Update: Nivolumab Plus Chemo Extends Survival for Chinese Gastric Cancer Patients
Introduction Gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma are among the most aggressive malignancies, particularly in their advanced stages. The CheckMate 649 trial previously established nivolumab plus chemotherapy as a superior first-line treatment compared to chemotherapy alone. With five years of follow-up, this latest analysis provides crucial insights into long-term survival, disease progression, and safety outcomes in Chinese patients. Given that nivolumab plus chemotherapy has been approved in over 50 countries as a first-line treatment, this updated evaluation assesses whether its benefits remain sustained over time in this population.
