Taste and smell dysfunction in patients receiving chemotherapy: a review of current knowledge

Abstract.

Disorders of taste are prevalent in patients undergoing chemotherapy and often have a negative impact on quality of life and nutrition. We now present a review of the physiology of taste and smell and a discussion of the multiple causes of disturbances in these senses in patients undergoing standard- and high-dose chemotherapy. A better understanding of the complex and often multifactorial etiology of taste dysfunction should enable the clinician to institute measures to minimize the impact of these disturbing changes.
