<p>Here we report the guidelines for surgical intervention on vulnerable elderly patients with colorectal cancer. Appropriate preoperative and intraoperative evaluations are important when performing surgery to treat elderly patients with colorectal cancer. Preoperative risk factors including deterioration of physical and cognitive function, malnutrition, comorbidities, polypharmacy, and decreases in skeletal muscle mass are associated with increased rates of postoperative complications and death. Limiting intraoperative fluid administration, fluid management based on goal-directed therapy (GDT), and anesthesia-depth management using EEG monitoring to prevent hypothermia, cutaneous injury, muscular damage, neuropathy, and circulatory disturbance lead to reduced postoperative complications. However, there are insufficient data to establish a clinically significant association between risk factors and postoperative complications. Moreover, there are no data to determine if surgical intervention results in acceptable outcomes for vulnerable patients who undergo invasive surgery and who are poor candidates for standard treatment. In order to solve these problems, it is necessary to accumulate and analyze data based on comprehensive geriatric assessment (CGA).</p>
