Yasunobu Ishizuka, MD, on Gastric Cancer: Does Nivolumab Infusion Time of Day Matter?
2024 ASCO GI Cancers Symposium
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).

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).

Michael K. Gibson, MD, PhD, of Vanderbilt University Medical Center, discusses phase III findings on chemotherapy plus camrelizumab in the ESCORT-NEO trial of patients with resectable esophageal squamous cell carcinoma; and phase III SKYSCRAPER-08 results on first-line tiragolumab plus atezolizumab and chemotherapy in the same patient population (Abstracts LBA244 and 245).

Van K. Morris, MD, of The University of Texas MD Anderson Cancer Center, discusses phase II results on using circulating tumor DNA (ctDNA) as a predictive biomarker of adjuvant chemotherapy in patients with stage II colon cancer. During the trial, no improvement in ctDNA clearance was observed after 6 months of chemotherapy following resection of disease. Dr. Morris notes that future trials should account for evolving assay performance in patients with colorectal cancer (Abstract 5).

Manish A. Shah, MD, of Weill Cornell Medical College, discusses phase III findings of the KEYNOTE-590 study, which shows that, after 5 years, the use of pembrolizumab plus chemotherapy improved survival with durable efficacy, compared with placebo plus chemotherapy, in patients with untreated advanced esophageal cancer (Abstract 250).

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).
