Recurrent Metastatic Gastrointestinal Stromal Tumor

Lutathera (lutetium [¹⁷⁷Lu] oxodotreotide) has been recommended for approval by the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) for the treatment of patients with unresectable or metastatic, progressive, well-differentiated (grade 1 and grade 2), somatostatin receptor positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

Tanios Bekaii-Saab, MD, discusses the the promise of napabucasin in pancreatic cancer.

In a 17-0 vote, the FDA’s Oncologic Drugs Advisory Committee unanimously recommended the approval of ABP-215, a biosimilar for bevacizumab.

Weijing Sun, MD, has been appointed the new Sprint Foundation Professor of Medical Oncology and the director of the Division of Medical Oncology at The University of Kansas School of Medicine and The University of Kansas Cancer Center.

David J. Pinato, MD, PhD, NIHR Academic Clinical Lecturer in Medical Oncology, resident, Royal Brompton Hospital and Imperial College London, discusses an analysis of intra-tumor heterogeneity in the regulation of immune-tolerogenic pathways in primary and metastatic hepatocellular carcinoma (HCC). 

Ann-Lii Cheng, MD, discusses a phase III trial of lenvatinib vs sorafenib in the first-line treatment of patients with unresectable hepatocellular carcinoma.

Luis A. Diaz Jr, MD, head, Division of Solid Tumor Oncology, Memorial Sloan Kettering Cancer Center, discusses the recent FDA approval of pembrolizumab (Keytruda) for microsatellite instability-high (MSI-H) colorectal cancer and other tumor types.

A large analysis of data comparing selective internal radiotherapy (SIRT) plus chemotherapy to chemotherapy did not show expected improvements in survival, but an unanticipated benefit was observed with SIRT in patients with metastatic colorectal cancer.

Overall survival was prolonged with treatment with ziv-aflibercept compared to placebo across subgroups of patients with metastatic colorectal cancer with wild-type and mutated <em>RAS, KRAS,</em> and <em>BRAF</em> genes.

Panitumumab has been approved by the FDA in combination with FOLFOX as a frontline treatment for patients with <em>RAS</em> wild-type metastatic colorectal cancer.

Treatment with lenvatinib in the first-line setting of unresectable hepatocellular carcinoma improved progression-free survival by 3.7 months and was noninferior for overall survival (OS) compared with sorafenib.

Yelena Y. Janjigian, MD, attending physician, Memorial Sloan Kettering Cancer Center, discusses findings of CheckMate-032, a study of nivolumab (Opdivo) with or without ipilimumab (Yervoy) in patients with advanced/metastatic chemotherapy-refractory gastric, esophageal, or gastroesophageal junction cancer.

Options for treating patients with hepatocellular carcinoma may currently be limited, with most physicians turning to a tyrosine kinase inhibitor for advanced disease, but physicians may soon be able to choose between a TKI and immunotherapy.

Luis A. Diaz Jr., MD, head, Division of Solid Tumor Oncology, discusses pembrolizumab (Keytruda) therapy for microsatellite instability-high colorectal cancer and other tumor types.

Tanios Bekaii-Saab, MD, professor of Medicine, Mayo Clinic, discusses results of the CanStem111P trial, a phase III study of napabucasin plus nab-paclitaxel with gemcitabine in adult patients with metastatic pancreatic adenocarcinoma.

Drug manufacturer XBiotech has cancelled the phase III XCITE study of MABp1 (Hutruo; formerly Xilonix) in patients with advanced colorectal cancer, following a second prospectively planned, unblinded analysis.
