Gastrointestinal Cancer

Tanios S. Bekaii-Saab, MD, FACP, shares key topics covered in the 17th Annual ISGIO meeting and its significance in the ever-evolving GI cancer space.

Combination CDK4/6 and MEK inhibition was “highly synergistic” in killing pancreatic neuroendocrine tumor cells in vitro and effectively suppressed PNET growth in mice.

Marianne Pavel, MD, discusses the progression-free survival of patients with pancreatic and midgut neuroendocrine tumors who are treated with lanreotide autogel in the phase 2 CLARINET FORTE trial.

Retreatment with Lutathera-based peptide receptor radionuclide therapy has been shown to have an encouraging survival benefit with an acceptable safety in patients with neuroendocrine tumors.

Edward Wolin, MD, discusses the safety profile of 177Lu-dotatate in patients with advanced neuroendocrine tumors.

Investigators are evaluating the combination of telotristat ethyl and Lutathera with a goal to improve progression-free survival in patients with well-differentiated neuroendocrine tumors in a randomized, phase 2 study that was highlighted during the 2020 NANETs Virtual Symposium.

Longer-term data demonstrated that treatment with the radiopharmaceutical Lutathera continued to show low rates of toxicity among patients with somatostatin receptor–positive neuroendocrine tumors.

Although chemotherapy remains the benchmark for drug development in pancreatic cancer, signals seen with selective KRAS-targeted agents, PARP inhibitors, and metabolic agents suggest that novel approaches do have the ability to prolong survival in the advanced setting.

John Zalcberg, ​PhD, OAM, discusses the management of patients with gastrointestinal stromal tumor​.

Deirdre J. Cohen, MD, MS, an expert in pancreatic and other gastrointestinal cancers as well as an accomplished clinical trial leader, has joined Mount Sinai Health System as Director of the Gastrointestinal Oncology Program and Medical Director of the Cancer Clinical Trials Office at The Tisch Cancer Institute.

Frontline sintilimab injection in combination with bevacizumab biosimilar injection resulted in a statistically significant improvement in progression-free survival and overall survival compared with sorafenib in patients with advanced hepatocellular carcinoma.

Over the past decade in gastrointestinal cancer treatment, the acknowledgement that cancer is heterogeneous and likely polyclonal has prompted a shift from gene testing for some patients, to many patients.

The Japanese Ministry of Health, Labor, and Welfare has approved the antibody-drug conjugate trastuzumab deruxtecan for the treatment of patients with HER2-positive unresectable advanced or recurrent gastric cancer that has progressed following chemotherapy.

The FDA has granted a fast track designation to DKN-01 for the treatment of patients with gastric and gastroesophageal junction adenocarcinoma whose tumors have high DKK1 expression, who have progressed on or after a fluoropyrimidine- and platinum-containing chemotherapy, and HER2/neu targeted therapy, if appropriate.

Findings from clinical trials evaluating HER2-directed and immunotherapeutic approaches for treating patients with gastric cancer are among recent data attracting interest from experts in the gastrointestinal cancer field.

Ivosidenib demonstrated a consistent trend toward improved overall survival compared with placebo in treatment-naïve patients with IDH1-positive cholangiocarcinoma, although the benefit was not determined to be statistically significant.

The addition of nivolumab to chemotherapy resulted in a statistically significant improvement in progression-free survival and elicited higher overall response rates in patients with previously untreated advanced or recurrent gastric and gastroesophageal junction cancer.

Ronan J. Kelly, MD, MBA, discusses the rationale to conduct the phase 3 CheckMate-577 study in esophageal or gastroesophageal junction cancer.

First-line treatment with the combination of nivolumab and chemotherapy led to a statistically significant survival benefit among previously untreated patients with PD-L1–positive advanced gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma versus chemotherapy alone.

The addition of durvalumab to tremelimumab showed modest activity in patients with advanced neuroendocrine tumors of gastroenteropancreatic and lung origins.

Frontline pembrolizumab plus chemotherapy significantly improved overall survival, progression-free survival, and objective response rates compared with chemotherapy alone in patients with locally advanced unresectable or metastatic esophageal cancer.

Lenvatinib plus pembrolizumab showed early antitumor activity and tolerability in previously treated patients with advanced solid tumors.

The novel VEGFR, FGFR, and CSF-1R inhibitor surufatinib yielded a statistically significant and clinically meaningful progression-free survival benefit compared with placebo in patients with advanced pancreatic neuroendocrine tumors.

Overall survival was significantly improved in patients who received hepatic arterial infusion chemotherapy with oxaliplatin, fluorouracil, and leucovorin compared with transarterial chemoembolization.

John Zalcberg, ​PhD, OAM, discusses updated results from the phase 3 INVICTUS trial in advanced gastrointestinal stromal tumor.

The novel broad-spectrum KIT and PDGFRα inhibitor ripretinib continued to demonstrate clinically meaningful benefit as a fourth- or later-line treatment for patients with advanced gastrointestinal stromal tumors.

Improvements in disease-free survival and progression-free survival were observed in patients with progressive pancreatic or midgut neuroendocrine tumors whose frequency of dosing for lanreotide Autogel was increased from 120 mg every 28 days to every 14 days.

In an interim analysis of a subset of patients with intrahepatic cholangiocarcinoma harboring FGFR2 fusions/rearrangements, futibatinib was shown to be efficacious and tolerable.

Timothy Cragin Wang, MD, discusses the advent of immunotherapy and how it has revolutionized multiple areas of cancer treatment; however, the transformative potential of the modality has been mild in the field of colorectal cancer.

Neoadjuvant nivolumab shrank tumors in 29% of patients with hepatocellular carcinoma at high risk for recurrence, which may kickstart the ablation effect of electroporation.
