[A Case of Gastrointestinal Perforation in a Patient with Colon Cancer and Stent Placement during Bevacizumab Treatment, Alleviated with Conservative Therapy].

Abstract The case involved a 52-year-old man. He was diagnosed with sigmoid colon cancer and multiple liver and lung metastases. After placement of a metallic stent for circumferential stricture, 5-fluorouracil/Leucovorin/oxaliplatin (FOLFOX4) plus bevacizumab therapy was introduced. After 17 courses, gastrointestinal perforation was noted at the site of stent placement, but this was alleviated with conservative therapy. Although gastrointestinal perforation is known to be a serious complication that occurs during chemotherapy combined with bevacizumab, further studies are needed to investigate the incidence of gastrointestinal perforation after stent placement more fully.
