About this trial
In 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.
