Ileal perforation at the site of peritoneal metastasis with intestinal infiltration by dual EGFR-VEGF pathway inhibition in an EGFR-mutant non-small cell lung cancer patient
摘要
Gastrointestinal (GI) perforation including ileal perforation is a rare complication of antivascular endothelial growth factor (anti-VEGF) therapy. Risk factors of GI perforation have not been fully understood. This report highlights the case of a patient who experienced GI perforation at the site of peritoneal metastasis with intestinal infiltration immediately after treatment with dual epidermal growth factor receptor (EGFR)-VEGF pathway inhibition agents for EGFR-mutant non-small cell lung cancer (NSCLC). The administration of dual EGFR-VEGF pathway inhibition agents in EGFR mutant NSCLC patients appears to elevate the risk of GI perforation. This report provides insights into the association between EGFR mutant NSCLC and the susceptibility to GI perforation following treatment with dual EGFR-VEGF pathway inhibition agents.
