SOMESTHESIA IN CANCER PATIENTS: VARIABILITY AND INFLUENCE ON EATING EXPERIENCE

The context and objectives:
In the context of cancer patients’ malnutrition, enhancing food liking and eating pleasure is a crucial and a well-known way to contribute to patients’ quality of life. Previous research results showed that chemotherapy-induced olfactory and gustatory modifications influence food behavior of cancer patients. However, food perception is a multi-sensory phenomenon that also involves the sense of somesthesia (touch). Somesthesia includes various sensations: tact (perception of roughness), mechanics (perception of consistency, firmness), temperature and the trigeminal system (irritating or pungent sensations). These kinesthetic sensory characteristics constitute food somesthetic properties. Evidence showed that chemotherapy induced side effects includes mouth dryness and mouth sores, which could further impact cancer patients’ food choices and preferences. Somesthesia is linked with food texture, yet the importance of it in relation to the overall food perception remains unexplored in cancer patients.

It is hypothesized that modifying the food physical properties would improve the appreciation and intake of foods that could help cancer patients who encounter somesthesia related side effects. The overall objective of this PhD project is to explore the role of somesthesia in the food liking and its cross-link with taste and smell perception in cancer patients.

Main missions:
The PhD candidate is expected to:

  • Review the existing literature on cancer patients’ somesthesic sensitivity in relation to the physical properties of food and beverages.
  • Learn standard self-reported and instrumental methodologies including running questionnaires, interviews and focus groups, and psychophysical sensory tests.
  • Formulate original research hypotheses and contribute to the design of the experiments and to the ethical file.
  • Conduct /coordinate the clinical intervention studies. Conduct the statistical analyses.
  • Write scientific papers targeting top ranked international journals.
  • Attend congresses, workshops, meetings, media events in order to disseminate research results.
  • Work on the compensation of the alterations observed in patients and formulate recommendations about personalised healthcare and support tools for patients.

The profile and eligibility:
The candidates must have obtained a Master’s level degree in Food science, Clinical nutrition, Sensory sciences or related fields in food behavior or medical science. A strong interest in the field of cancerology would be appreciated.

Additional skills are required, such as:

  • Strong skills in statistics
  • Interest in both theoretical and empirical questions
  • Excellent communication skills
  • Real interest for translating scientific results and methodologies into deliverables directly exploitable in the clinical field
  • International mobility
  • Advanced level in both oral and written English
  • Knowledge of French would be appreciated

The conditions:

  • September 2020 – August 2023: 36-month PhD position at University Lyon 1/University of Copenhagen/Institut Paul Bocuse Research Center
  • Salary: PhD position 25k€ € gross/year (based on French ANRT recommendations for CIFRE)
  • Travel expenses for secondments in Denmark

The location:
The PhD student will be mainly based at IPBR (in Ecully, near Lyon) as part of the Nutrition and Eating Behaviour Group with frequent interactions with University Claude Bernard Lyon 1 (easily accessible from Institut Paul Bocuse). Planning and length of secondments at the Department of Food Science at the University of Copenhagen in Denmark will be defined according to the project and candidates’ profile.

Occasional trips to attend congresses, conferences, workshops and meetings with external collaborators are expected as part of the usual researcher’s life.
