Ian Chau, MD, on Gastrointestinal Cancers: Real-World Effectiveness of Nivolumab Plus Chemotherapy

Ian Chau, MD, of The Royal Marsden Hospital, discusses reportedly the first study to evaluate the real-world effectiveness of nivolumab as a first-line treatment of advanced gastric, gastroesophageal junction, or esophageal adenocarcinoma. The combination therapy improved overall survival compared with chemotherapy alone. Dr. Chau presents the 18-month follow-up results (Abstract 295).
