특집: 암 환자의 혈당관리

Both diabetes mellitus and cancer are common diseases whose incidence is increasing globally. Epidemiologic evidence suggests that the prevalence of cancer is increasing in diabetic patients, and both hyperglycemia and hypoglycemia may lead to poor prognosis and complications in such patients undergoing cancer therapy. Nevertheless, managing glucose in patients with diabetes and cancer can pose a significant clinical challenge. As there are no evidence-based guidelines for treating diabetes in patients with cancer, an individualized approach is required. Diabetes self-management education is a critical element of care for cancer patients with diabetes. We discuss the management of diabetes in relation to cancer surgery, chemotherapy including glucocorticoids, and enteral and parenteral nutrition. We also discuss management of hyperglycemia in patients with advanced cancer approaching end of life care.
