RESUMO
A 73-year-old man with advanced descending colon cancer and peritoneal metastases underwent a self-expandable metallic stent placement under fluoroscopic guidance on October 2007. The stent placement was successful without early complication. After 6 courses of FOLFOX4 followed by 7 courses of FOLFIRI, he received Bevacizumab-based chemotherapy from August 2008. In April 2009, he was admitted to our hospital with severe abdominal pain due to perforation of descending colon. Although emergent surgery was performed, he developed DIC and died on the 21 postoperative days. This case suggests that metallic stent placement for colorectal cancer cases might increase the risk of bowel perforation during Bevacizumab-based chemotherapy.

Reactivation of hepatitis B virus (HBV) has recently been reported as a fatal complication in patients undergoing cytotoxic chemotherapy. We herein describe a case of reactivation in a 76-year-old man who had undergone pelvic exenteration for colorectal cancer (CRC). He was treated with a modified FOLFOX6 chemotherapy regimen after the operation. Thirteen months later, his laboratory data showed severe liver dysfunction. His hepatitis B surface antigen (HBsAg) test was positive, and his HBV-DNA level was elevated. We diagnosed the patient with HBV reactivation as his HBsAg test was negative before starting chemotherapy. His liver dysfunction improved after administration of entecavir. This is the first report describing HBV reactivation following chemotherapy for an HBsAg-negative CRC patient.
