Ian Chau, MD, on Gastrointestinal Cancers: Real-World Effectiveness of Nivolumab Plus Chemotherapy
2024 ASCO GI Cancers Symposium
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).

Riccardo Lencioni, MD, of the University of Pisa School of Medicine, discusses phase III results from the EMERALD-1 study of durvalumab plus bevacizumab plus TACE (transarterial chemoembolization) in patients with embolization-eligible unresectable hepatocellular carcinoma. Compared with TACE alone, this combination is the first immune checkpoint inhibitor–based regimen to improve progression-free survival and has the potential to set a new standard of care in this disease, according to Dr. Lencioni (Abstract LBA432).

Jennifer Yon-Li Wo, MD, of Massachusetts General Hospital, discusses the local failure rate of non-ablative hypofractionated radiation therapy in combination with the immune checkpoint inhibitors ipilimumab and nivolumab compared to ablative SBRT to treat metastatic microsatellite-stable colorectal and pancreatic cancers as a secondary analysis of four prospective trials. Dr. Wo and her team found that, despite using nearly half the radiation dose in those who received immunotherapy, there was no significant difference in local failure rates (Abstract 752).

Yasunobu Ishizuka, MD, of Japan’s Aichi Cancer Center, discusses study results showing that scheduling infusions of nivolumab monotherapy before mid-afternoon for patients with metastatic gastric cancer may alter treatment efficacy. Several studies have suggested that circadian rhythm is essential in immune system function, including anticancer immunity (Abstract 268).

Ian Chau, MD, of The Royal Marsden Hospital, discusses an analysis from the CheckMate 648 study on quality-adjusted time without symptoms and toxicity in patients with unresectable advanced esophageal squamous cell carcinoma. Patients treated with nivolumab plus ipilimumab and nivolumab plus chemotherapy compared with chemotherapy alone experienced longer quality-adjusted survival (Abstract 251).

Anant Ramaswamy, DM, of Tata Memorial Centre, discusses phase III results of a study that added docetaxel to a doublet regimen of fluorouracil or capecitabine and oxaliplatin, which did not improve overall survival in patients with advanced gastroesophageal junction and gastric cancers. Continuing chemotherapy beyond 6 months also did not appear to improve survival in this population (Abstract LBA248).
