Zollinger-Ellison syndrome (ZES) is a disease entity which refers to the triad of severe peptic ulcer disease (PUD), gastric acid hypersecretion and non-beta cell gastrin-secreting tumor primarily of the pancreas and duodenum (gastrinoma).
Approximately two-thirds of patients have sporadic ZES while the rest is part of multiple endocrine neoplasia type 1.
ZES should be considered in the differential diagnoses of patients who present with abdominal pain, malabsorption and chronic watery diarrhea.
A high index of clinical awareness is necessary to correctly diagnose ZES.
A triple-drug combination therapy comprising encorafenib, binimetinib, and cetuximab significantly improved survival compared with the current standard of care chemotherapy in patients with BRAF V600E-mutant metastatic colorectal cancer (mCRC) who had failed one or two prior treatments, according to the BEACON CRC study presented at the recent ESMO World Congress on Gastrointestinal Cancer (ESMO GI).
Reducing the dose of regorafenib did little to affect the overall tolerability of the drug in patients with metastatic colorectal cancer (mCRC), according to the phase II REARRANGE* trial presented at ESMO GI 2019.
