Changes in the sense of taste and smell in cancer patients

The HungerNdThirst Foundation has now signalled a possible negative impact of changes in the sense of smell and taste on patient recovery and quality of life. The foundation is focusing its attention on finding ways to improve the sensation of taste for cancer patients (and ex-patients) by modifying food, for example. The foundation has asked the Science Shop at Wageningen University and Research to help answer certain research questions in order to provide patients and care professionals with suitable practical information on taste and smell changes and the impact of these changes on nutrition.

Results

Within the various subprojects it appeared that the prevalence of changes in smell and taste is high in cancer patients who undergo chemotherapy. This makes it important to discuss smell and taste problems in the daily care practice. Tailor-made solutions for the patient are needed, with a focus on taste perception and tasty food, instead of eating because it has to be done.

In practice it proves difficult to have cancer patients eat well and tastefully. That is why it is important to translate the available knowledge into practical solutions that can be used in the daily care practice and in the daily life of the patient. More research into the validation of available tools for the daily care practice can also contribute to the improvement of the care surrounding olfactory and taste changes in cancer patients.

As a result of the project, four fact sheets were drawn up: for doctors, nurses, dietitians and the patients themselves. These factsheets (in Dutch) contain information about smell and taste changes and practical tips and advice. With these factsheets we hope to give patients and caregivers the tools to continue making healthy choices during illness and treatment, despite smell and taste changes. This allows the recovery to be promoted and patients can continue to eat tasteful for a better quality of life.
