Chemotherapy is the most commonly utilized therapeutic strategy among the numerous cancer treatments. These chemotherapeutic agents have a variety of adverse reactions, one of which is taste alteration (TA), which substantially influences the patient's nutritional status and quality of life (QoL). The study aims to assess TAs, associated factors, and the nutritional status and QoL of cancer patients undergoing chemotherapy. An observational cross-sectional study was carried out for 6 months, among cancer patients diagnosed with TA. Data was collected using a chemotherapy-induced taste alteration scale (CiTAS). Demographic details of the patients, factors associated with TA, details regarding chemotherapeutic agent used, number of current chemotherapy cycles etc, were recorded using a self-designed data collection form. Nutritional status and QoL on cancer patients were collected using Mini nutritional assessment – short form (MNA-SF) and EuroQol 5 dimension 5 levels (EQ5D5L), respectively, and statistical package for the social sciences (SPSS) software version 29 was used for the analysis of data. A significant association was observed between TA and QoL. There was also a significant association between TA and predisposing factors such as nausea and dry mouth, which was obtained from the Chi-square test. Male patients were found to have higher TA than female patients. TA has also affected various aspects of QoL, such as mobility, pain, and discomfort. Patients experiencing mouth dryness or xerostomia had higher TA than others. A negative association was seen between TAs and nutritional status. This study shows a significant relationship between gender and TA, dry mouth, nausea, and TA. Several QoL factors like mobility, pain/discomfort, and TA were also observed. Despite this study not observing any statistical association between nutritional status and TA, clinically, most of the patients with higher TA were malnourished. This study concluded that there was a relationship between TA and QoL and that nausea and dry mouth are the predisposing factors for TA.
