Primary

Measure	Time frame
Five-year overall survival rate of laparoscopic surgery group and open surgery group	—

Secondary

Measure	Time frame
Comparative study of 5-year recurrence-free survival rate between laparoscopic surgery group and open surgery group Safety and efficacy of preoperative treatment cases (adverse events, treatment completion rate, response rate, recurrence-free survival, overall survival, etc.) Study on surgical procedure, postoperative complication rate, and risk factors for postoperative complications Study on postoperative abdominal scar hernia Whether postoperative adjuvant chemotherapy is performed and its details Study on recurrence site and post-recurrence treatment Effects of postoperative complications on long-term outcome Treatment results of cases invading other organs Treatment results of a case with distant metastasis (cStage IV) Treatment results in obese cases (BMI, VFA, SFA) Treatment results of laparoscopic surgery in the elderly Treatment results of para-aortic lymph node dissection Treatment results for patients with coexisting diseases (heart disease, lung disease, oral antiplatelet drug etc.) Examination of the depth of primary lesion and the diagnostic ability of lateral lymph node metastasis by preoperative MRI Short-term and long-term results of lateral dissection Study on lymph node dissection effect using dissection index Subgroup analysis Analyze the above evaluation items for each subgroup such as tumor occupancy site and pStage	—
