Jennifer Yon-Li Wo, MD, on Colorectal and Pancreatic Cancers: New Findings on SBRT With Ipilimumab and Nivolumab
2024 ASCO GI Cancers Symposium
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).

Ken Kato, MD, PhD, of Japan’s National Cancer Center Hospital, discusses the first comprehensive findings on biomarkers from the CheckMate 648 study. These results further corroborate the clinical efficacy of nivolumab plus chemotherapy and nivolumab plus ipilimumab in the first-line treatment of advanced esophageal squamous cell carcinoma. According to Dr. Kato, the data suggest an overall survival benefit across multiple biomarker subgroups (Abstract 252).

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).

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).

Lorraine A. Chantrill, PhD, MBBS, of Australia’s Wollongong Hospital, New South Wales, discusses phase II findings on the combination of nab-paclitaxel plus carboplatin as a first-line treatment for patients with gastrointestinal neuroendocrine carcinomas. According to Dr. Chantrill, this regimen appears to be active in these tumors and warrants further evaluation in a phase III trial (Abstract 589).

Milind M. Javle, MD, of The University of Texas MD Anderson Cancer Center, discusses phase II results on tinengotinib, a next-generation FGFR inhibitor that seems to overcome acquired resistance and shows efficacy in patients with cholangiocarcinoma with other FGFR alterations who are not eligible for FGFR2-targeted treatments. A phase III global study is currently enrolling to further evaluate the efficacy and safety of this agent vs physician’s choice in FGFR-altered, chemotherapy- and FGFR-inhibitor–refractory or relapsed disease.
