Somesthesia in Cancer Patients: Variability and Influence on Eating Experience

Patients with cancer are at high risk of denutrition, in France 39% of these patients suffer of malnutrition. This can affect the immunity, the mental balance and impact the treatment response and the quality of life. Cancer treatments cause many side effects related to food intake as well as sensory alteration, important factor contributing to reduced appetite and inadequate food intake to cancer patients. SOMEST'ALIM2 is a prospective, non-randomized, monocentric, multisite study that aims to evaluate the appreciation of patients with different types of cancer (digestive, gynecological, breast, ear, nose and throat (ENT) or lung) of two different food versions (sweet and salty), in standard and enhanced version. Patients must be under treatment from at least two months, and before food testing their sensory capacity and quantity and the quality of their saliva will be tested. They will also be asked to answer to different questionnaires: socio-demographics, appreciation of food samples, self-assessment of oral symptoms and sensory perceptions, MD, Quality of Life Questionnaire (QLQ-C30) and food quality of life questionnaire. In a context of sensory alterations patients should appreciate more the enhanced food versions. Patients perception of food will be evaluated using a visual analogue scale and results will be correlated with saliva characteristics, subjective sensory perceptions and oral symptoms.
