Brief Summary

Cancer patients are at high risk for undernutrition. A study with head and neck cancer patients showed that 50% suffered from undernutrition (Prevost et al., 2014). Sensory alterations may also involve sensory changes from the physiological structures of the mouth or neural pathways and hedonic changes, i.e., although food may taste the same as usual, that taste is no longer judged as pleasant. These changes lead to an aversion to food and a decrease in the pleasure of eating (Bernhardson et al., 2009).

Despite the large number of published studies on taste and smell alterations in diverse cancer populations, few have examined other dimensions of oral sensory alterations. Studies focusing on somesthesia have mostly been conducted in the area of oral physiology or stomatology in relation to oral pain and rehabilitation (Howes, Wongsriruksa, Laughlin, Witchel, \& Miodownik, 2014).

Regarding food perception, somesthesia provides information about both texture, temperature, and trigeminal sensations. These sensations are detected by mechanical, thermal, nociceptive receptors present throughout the oral epithelium (Simons \& Carstens, 2008). In addition to taste and smell, food perception is influenced by oral somatosensation and studies have demonstrated an interrelated relationship between these oral sensations (Spence, Piqueras-Fiszman 2016). Therefore, ther might have a correlation between oral somatosensation and food preferences, subsequently influencing eating behavior and food consumption. A standard method, using a so-called Von Frey Hair monofilament, to assess tactile sensation was developed by Etter et al. (Etter, N. M et al.,. J. Vis. Exp. 2020) but has so far been only minimally used in Ear, Nose and Throat (ENT) cancer (Bearelly, Wang, \& Cheung, 2017; Bodin, Jäghagen, \& Isberg, 2004; Elfring, Boliek, Seikaly, Harris, \& Rieger, 2012).

The aim of the study is to determine the variability and role of somatosensory perception (texture, pungency transmitted through the trigeminal system, and temperature) on food preferences in cancer patients compared to healthy volunteers.

Primary Outcome Measures

Name	Time	Method
Oral tactile sensitivity score	Up to 3 months after recruitment.	The primary endpoint of the study is to measure oral tactile sensitivity using the Von Frey Hair monofilament pressure test in head and neck cancer patients compared to healthy volunteers. This will be assessed at recruitment for healthy volunteers and between 1 to 3 months after recruitment for head and neck cancer patients.

Secondary Outcome Measures
