Anthony B. El-Khoueiry, MD, on Hepatocellular Carcinoma: Expert Perspective on Novel Additive Strategies
2022 ASCO Gastrointestinal Cancers Symposium
Anthony B. El-Khoueiry, MD, of the University of Southern California, Norris Comprehensive Cancer Center, discusses two key phase III studies of first-line treatment in hepatocellular carcinoma: the LAUNCH trial, which explored lenvatinib combined with transarterial chemoembolization for advanced disease; and the HIMALAYA trial, which studied tremelimumab and durvalumab for unresectable disease. The latter trial may represent a new standard of care, according to Dr. El-Khoueiry.

Heinz-Josef Lenz, MD, of USC Norris Comprehensive Cancer Center, discusses phase II results from the CheckMate 9X8 study, which compared nivolumab plus fluorouracil/leucovorin/oxaliplatin (mFOLFOX6) and bevacizumab vs mFOLFOX6 and bevacizumab in the first-line treatment of metastatic colorectal cancer. A subgroup of patients may benefit from adding nivolumab to the standard of care in this setting (Abstract 8).

Yu Sunakawa, MD, PhD, of Japan’s St. Marianna University School of Medicine, discusses his findings from the DELIVER trial, which suggest the gut microbiome may predict skin toxicities in patients with advanced gastric cancer who are treated with nivolumab. In addition, some single nucleotide polymorphisms, such as NOTCH1, SEMA4D, NLRC5, and IL-6R genes, may potentially become markers for diarrhea and skin toxicities with this agent.

Afsaneh Barzi, MD, PhD, of City of Hope Comprehensive Cancer Center and AccessHope, discusses results from a phase I/II study of regorafenib and pembrolizumab in refractory microsatellite-stable colorectal cancer. Although the trial did not meet its primary endpoint, the median overall survival is “provocative,” says Dr. Barzi. An analysis of biomarkers to identify patients with a longer duration of benefit is ongoing (Abstract 15).

Kohei Shitara, MD, of Japan’s National Cancer Center Hospital East, discusses a long-term data follow-up from CheckMate 649, which support the continued use of nivolumab plus chemotherapy as first-line treatment in patients with advanced gastric, gastroesophageal junction, and esophageal adenocarcinomas (Abstract 240).

Tanios S. Bekaii-Saab, MD, of Mayo Clinic, discusses new findings from the KRYSTAL-1 study, which suggested adagrasib monotherapy is well tolerated and demonstrates clinical activity in pretreated patients with unresectable or metastatic pancreatic cancer or other gastrointestinal tumors harboring a KRAS G12C mutation. Adagrasib is an inhibitor of the KRAS G12C mutation (Abstract 519).
