From guidelines to clinical practice: a roadmap for oncologists for nutrition therapy for cancer patients

Tackling malnutrition in cancer patients remains one of the most challenging tasks in clinical practice. Even though robust evidence exists stressing the role of nutritional status in relation to treatment outcome, its appropriate consideration in clinical practice is often lacking. In this review, we discuss the significance of nutritional status and of malnutrition for the cancer patient. Drawn from experience and from current recommendations of the European Society for Clinical Nutrition and Metabolism (ESPEN), we propose concrete and manageable steps to routinely incorporate nutritional aspects in today’s oncological clinical practice.
