After the surgery, adjuvant chemotherapy will be administered, and total perioperative chemotherapy will be administered with 12 cycles. The primary end points is overall survival, also the short-term perioperative outcomes and long-term oncological outcomes will be compared between the control and experimental group. Random allocation will be carried out with the consent of patients and their guardians after successful SEMS placement, and 204 patients will be distributed between the two groups by 1:1.', 'detailedDescription': 'It is known that approximately 30-40% of colorectal cancer require emergency surgery. Of these, the colonic obstruction accounts for 80% of situations requiring emergency treatment and colon perforation appears in 20%. In patients with colorectal cancer patients who require emergency surgery, there are higher postoperative complication rates, mortality rates, and ostomy formation rate than those who do not. In aspect of oncologic outcomes, long-term survival also appears to be worse in patients undergoing emergency surgery. Despite recent active screening for colorectal cancer, some studies have reported that the proportion of colorectal cancer obstruction and perforation requiring emergency surgery still occur as before. However, research on treatments to reduce postoperative complications and to increase long-term survival for patients with symptomatic colorectal cancer requiring emergency surgery remains inadequate.\n\nEmergency surgery cannot be avoided when colorectal perforation occurs due to colorectal cancer. Obstructive colorectal cancer has also traditionally been performed in emergency surgery with colorectal resection and ostomy composition. However, with the development of endoscopic equipment and technology, endoscopic stent (self-expandable metallic stent, SEMS) insertion has been feasible for patients with obstructive colon cancer and many researches about a bridge to surgery which means a surgery after adequate decompression and bowel lavage using SEMS placement have been reported that a bridge to surgery can reduce postoperative complications, stoma formation, and postoperative mortality in selective cases. Currently, such studies recommend the use of SEMS to improve short-term postoperative outcomes. However in aspect of long-term oncological outcomes, the results have not yet been established.\n\nIn this study, patients with obstructive colon cancer will be divided into two groups; in the control group, curative surgery will be performed within 2 weeks after successful SEMS placement, and in the experimental group, 3 cycles of neoadjuvant chemotherapy will be administered into patients who undergo successful SEMS placement and then curative surgery will be performed after neoadjuvnat chemotherapy. After the surgery, adjuvant chemotherapy will be administered, and total perioperative chemotherapy will be administered with 12 cycles. The primary end points is overall survival, also the short-term perioperative outcomes and long-term oncological outcomes will be compared between the control and experimental group. Random allocation will be carried out with the consent of patients and their guardians after successful SEMS placement, and 204 patients will be distributed between the two groups by 1:1. Through this study, we would like to identify that neoadjuvant chemotherapy followed by curative resection after successful SEMS placement for obstructive colon cancer can bring the improvement of short-term perioperative outcome and long-term oncological outcome.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '74 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* i.
