Abstract
BACKGROUND/AIM: Chemotherapy-induced taste alterations (TAs) affect approximately 53-84% of breast cancer patients with significant consequences on flavor perception, possibly leading to food aversion and changes in daily dietary habits. The aim of this study was to investigate the relationship between TAs and changes in food habits and body weight among early breast cancer (EBC) patients undergoing adjuvant chemotherapy. PATIENTS AND METHODS: TAs were prospectively evaluated in 182 EBC patients from April 2014 to June 2018. TAs, dietary habits, and body weight were collected by a trained dietician. TAs were classified into different subtypes according to the following basic taste perception: metallic, sweet, bitter, salty, sour, and umami taste. RESULTS: During adjuvant chemotherapy, a significant reduction in the consumption of bread, breadsticks, red meat, fat salami, snacks, added sugar, milk, and alcoholic beverages was observed, regardless of TAs onset. No correlation between these dietary changes and different TAs subtypes was found. Body weight remained stable in most EBC patients (71.4%) and was not influenced by TAs onset and by different TAs subtypes. CONCLUSION: EBC patients change their dietary habits during adjuvant chemotherapy, mostly following the World Cancer Research Fund recommendations, irrespective of TAs onset and without affecting body weight.
