[Taste and smell changes resulting from cancer therapies]

Cancer therapies often cause changes in taste and smell. In this article, three patients treated with immunotherapy, chemotherapy and targeted therapy who experience changes in taste or smell are presented. These patients report lower quality of life and altered eating habits due to these changes. The prevalence and type of taste and smell changes is diverse among different cancer treatments and individual patients. In clinical practice, diagnosis is supported by questionnaires, taste strips or smell sticks. It is important to acknowledge the changes in taste and smell and inform the patient about these changes. More tools become available to provide patients with personalized advise to adjust their meals to their new sense of taste and smell at home. Furthermore, hospital cooks are implementing new strategies to adjust meals to taste and smell alterations and individual preferences. Smell training is an option for patients with severe smell disorders.
