Gastrointestinal stromal tumors are morphologically spindle cell, epithelioid, or occasionally pleomorphic mesenchymal tumors of the gastrointestinal tract.
Signs and symptoms of gastrointestinal tumor include presence of abdominal mass (which may be an incidental finding in endoscopy), gastrointestinal bleeding, hemoperitoneum, anemia and gastrointestinal perforation.
Updates from the SECURE-IBD* registry reveal that treatment with thiopurine, either alone or in combination with tumour necrosis factor inhibitors (TNFis), for inflammatory bowel disease (IBD) was associated with a greater risk of severe COVID-19 compared with TNFis monotherapy.
