A 72-year-old woman having abdominal pain and high fever was diagnosed with KRAS wild-type sigmoid colon cancer, invading the urinary bladder and uterus with a pelvic abscess. Considering the difficulty of curative resection, we first performed sigmoid colostomy and abscess drainage. Remarkable tumor regression was indicated by CT and colonoscopy after 1 course of FOLFIRI and 5 courses of FOLFIRI+panitumumab. Following an additional 2 courses of panitumumab, sigmoidectomy and partial cystectomy were performed. Six courses of FOLFIRI+panitumumab were administered postoperatively and no recurrence has been observed for 7 months. FOLFIRI+panitumumab may be an effective preoperative chemotherapy for patients with KRAS wild-type locally advanced colon cancer.
