Oral Equilibrium in Cachexia

Oral cancer, a part of head-and-neck cancer (HNC), is associated with a high risk of cancer-associated weight loss causing cachexia which is still an understudied illness. Cachexia is a host-phagocytic syndrome caused by the multiple factors, resulting in the severity of heterogenic fashion. For the current review, a bibliographic search was done in PubMed and other databases for the English articles published from the year 1980 to 2021. Recent studies have revealed that cachexia associated with 35%-60% of all the oral cancer patients is either due to the implication of the tumor or obstruction of food intake for which a strong need for nutritional assistance and hydration is desired. The health of cancer individuals undergoing chemotherapy or bone marrow transplant is negatively affected by poor oral health and reduced dentition status. The impact of a deficient oral condition is not clearly understood to date, possibly due to the limited number of studies and a lack of widely accepted clinical trials to prevent cachexia. The masticatory function of such patients is drastically affected thus contributing to the decreased nutritional status causing wasting of tissues. The aim of this article is to provide substantial evidence that poor oral hygiene with an altered dentition status negatively influences the energy balance of oral cancer patients who experience wasting.
