[A Resectable Case of Highly Locally Advanced Cecal Cancer in an Elderly Patient after Bypass Surgery and Chemotherapy].

ABSTRACT

An 83-year-old woman underwent an examination for right lower abdominal pain and was diagnosed with highly advanced cecal cancer. CT showed no metastasis; thus, we attempted resection or bypass surgery. While no liver metastasis or peritoneal dissemination was observed intraoperatively, the circumflex region was highly infiltrated to the peritoneum and retroperitoneum. Considering the patient's age, resection was deemed overly invasive, so an ileum and transverse colon bypass surgery was performed. To downsize and safely remove the primary lesion, capecitabine plus bevacizumab was started. A CT examination performed after 3 courses revealed that the tumor had decreased in size. After the 4th course, surgery was performed. Intraoperative findings showed no obvious peritoneal dissemination, the tumor size was reduced, and the tumor was movable. A laparoscopic right hemicolectomy plus D3 dissection was performed. She was discharged on postoperative day 5. No obvious recurrence has been observed 6 months after surgery.
