We report a case of advanced sigmoid colon cancer resected via laparoscopic surgery after preoperative chemotherapy. A- 55-year-old man visited our hospital with diarrhea. CTrevealed a giant tumor in the sigmoid colon, and surrounding lymph node enlargement was also noted. The tumor appeared to be locally advanced; thus, preoperative chemotherapy was started. Due to the possibility of obstruction, we constructed an ileostomy laparoscopically. The tumor was found to be RAS wild, and 4 courses of mFOLFOX6 plus panitumumab were given. Follow-up CTshowed remarkable tumor reduction allowing laparoscopic resection; as such, laparoscopic sigmoidectomy was performed successfully. Chemotherapy with molecular-targeted drugs is a promising method to make laparoscopic surgery possible for advanced colorectal cancer.
