A 68-year-old man with abdominal mass and anorexia was diagnosed with transvers colon cancer invading the abdominal wall. Considering the difficulty of curative resection, we first performed ileostomy. After surgery, the patient received mFOL FOX6 with bevacizumab as neoadjuvant chemotherapy. After 10 course of the regimen, computed tomography revealed shrinkage of the lesion, with the efficacy evaluated as a partial response. The patient underwent right hemicolectomy and partial resection of the abdominal wall. The pathological findings was ypT3(SS), ypN3, ly0, v1, ypPM0, ypDM0, ypRM0, ypStage III b. On histopathological examination, the efficacy of the chemotherapy was evaluated as Grade 1b. The patient received adjuvant chemotherapy with mFOLFOX6 and remains well without any evidence of recurrence more than 7 months after surgery.
