A matter of taste: alteration in patients with cancer

Abstract

Taste alteration (dysgeusia) is a common nutritional impact symptom in people affected by cancer, as a result of either the cancer itself or its treatments. It can have a significant impact on oral intake and nutritional status. Taste alteration can also have a negative impact on food behaviours and quality of life. There is a paucity of evidence both on how the problem is assessed in patients and on strategies and guidelines to manage it. This article gives an overview of taste alterations in cancer, highlights recent reviews and summarises some key practical management themes.
