RESUMO

PURPOSE: Patients with cancer often experience nutritional challenges and are vulnerable to muscle mass loss. While substantial research is directed towards understanding how nutritional interventions affect clinical outcomes, insights into patients' personal experiences during these trials remain limited. This qualitative study aimed to gain a deeper understanding of how participation in the Protein Recommendations to Increase Muscle (PRIMe) trial affected patients' relationships with food. METHODS: A subset of patients who completed a minimum of one follow-up visit in the PRIMe trial participated in a semi-structured interview about their experience implementing dietary modifications to increase protein intake. Data from 26 patients with a recent diagnosis of stage II-IV colorectal cancer (non-cachectic) were included. Interviews were audio recorded, transcribed verbatim, and qualitative content analysis was applied. RESULTS: Most patients were male (65.4%) with stage II or III (69.2%) colorectal cancer and were a mean age of 57 ± 10 years. Five key themes emerged to provide a deeper understanding of patients' relationship with food after the PRIMe trial: (1) new positive perspectives on nutrition and coping with a cancer diagnosis; (2) embracing a comprehensive approach to food and nutrition; (3) facilitators promoting adherence to the intervention; (4) barriers challenging adherence to the intervention; and (5) shaping future dietary intake. CONCLUSION: This qualitative study explored the emotional and psychological effects of a clinical nutrition trial on patients, focusing on their relationship with food. It underscored the trial's comprehensive intervention and its enduring influence on patients, extending beyond the immediate intervention phase. The role of current perspectives, motivation, and knowledge acquisition on ability to adhere to dietary changes to increase protein intake were emphasized by patients and are key considerations for both clinicians and researchers.

RESUMO

Fortified snacks can increase nutrient intake among patients with cancer. The aim of this study was to identify snack foods preferred as potential vehicles for fortification and how experienced symptoms influence preferences.A study-specific survey among 150 patients identified snack foods for fortification, influence of symptom presence, desired nutrients and characteristics of a fortified snack, and perception of oral nutritional supplements.Patients had mainly breast, gastrointestinal, lung, and colorectal tumors. Soup, yogurt, cheese, fruit juice, egg products, and protein bars were identified as suitable fortified snacks by >60% of subjects. Desired characteristics for snacks included nutritious, flavorful, convenient, ready to eat, easy to chew, and easy to swallow. Vitamins, minerals, and protein were the nutrients of interest. Three clusters of symptoms were identified that predicted patients' desired characteristics of fortified snacks and satisfaction with food-related life. Patients in High and Moderate symptom clusters were more likely to have reduced food intake and higher consumption of oral nutritional supplements.Preferences for fortified snacks and their characteristics are influenced by symptom presence. The results of this study provide insight to guide the development of fortified snacks for patients with cancer.

RESUMO

PURPOSE: Oral nutritional supplements and fortified foods, here considered supplemented food products (SFP), are recommended as part of nutrition therapy guidelines to treat malnutrition among cancer patients. However, their successful use is limited by patients' failure to meet recommended intakes. This systematic review aimed to identify sensory preferences for SFP among cancer patients and evaluate the methodologies employed in sensory preference assessment. METHODS: A systematic search was conducted in several relevant databases yielding 1056 papers of which 19 met the inclusion criteria. Two authors independently selected papers and extracted findings. The included papers were categorized according to the focus of the preference assessment. RESULTS: Studies comparing sensory preferences for SFP of cancer patients with those of a control group suggested that the liking for SFP by cancer patients differs from healthy participants. Patient heterogeneity in site and stage of tumor, variation in study methodologies, and type of treatment complicated a conclusion regarding the effects of cancer treatment and taste changes on taste preferences. However, some general results were observed among the studies, such as the preference for fresh milk-based supplements when compared with other supplement types. CONCLUSION: This review highlighted the need for consistent reporting and control of variables that influence the sensory characteristics of SFP when sensory preferences are assessed in the clinical setting. Attention to these methodological details will enhance the reliability and accuracy of sensory preference assessment among cancer patients for realistic evaluation of SFP targeted to their nutritional needs.

RESUMO

This study assessed dietary and micronutrient intakes of head and neck cancer (HNC) patients at key points in the disease trajectory and evaluated the contribution of oral nutritional supplements (ONS) to micronutrient intake. HNC patients (n = 114) completed a three-day dietary record and a tool to assess Nutrition Impact Scores (NIS) at baseline, post-treatment, and follow-up. Foods were classified into food categories. Micronutrient, protein, and energy intakes were compared to European Society for Parenteral and Enteral Nutrition guidelines for cancer patients. The majority of patients did not meet recommended dietary intakes for vitamins D, E, C, folate, and magnesium at any study time point. Relative to baseline, the proportion of calories from milk, soup, and ONS significantly increased at post-treatment, while grain, meat, potato, baked dessert, and oil and sugar decreased (P < 0.03). At all study time points, patients categorized as high ONS consumers (>15% of total daily calories from ONS) had higher intakes of micronutrients (P < 0.003). They also had a higher NIS (P = 0.006) and experienced greater weight loss (P < 0.04) during the study, despite having similar energy intake to patients consuming <15% kcal from ONS. Fortification of usually consumed foods to improve micronutrient intake among cancer patients should be evaluated.

RESUMO

Hyperphagia and obsessive preoccupation with food are hallmark characteristics of Prader-Willi Syndrome (PWS). Although hyperphagia in PWS is linked to hypothalamic dysfunction, the underlying mechanisms behind this problem are poorly understood. Moreover, our understanding of how chemosensory perceptions and food choice/preferences relate to hyperphagia in individuals with PWS is very limited. This narrative review synthesizes studies that assessed chemosensory perceptions, food choices and food-related behaviours in PWS individuals and highlights knowledge gaps in research for further exploration. Twenty seven publications from relevant databases met inclusion criteria and were organized thematically by study technique in the review. Results suggested that PWS individuals have consistent preferences for sweet tastes and in most studies have exhibited a preference for calorie-dense foods over lower calorie foods. No firm conclusions were drawn concerning the chemosensory perceptions of PWS individuals and their influence on food preferences or choices; chemosensation among PWS individuals is an understudied topic. Current evidence suggests that eating behaviour in PWS is a complex phenomenon that involves a dysfunctional satiation and not excessive hunger. Food preferences, choices, and related behaviours and the impact of these on obesity management in those with PWS remain poorly understood and require further study using validated tools and methodologies.

RESUMO

PURPOSE: The purpose of this review was to examine studies of interventions for the prevention and management of taste and smell alterations (TSA) experienced by adult oncology patients. METHODS: Articles published between 1993 and 2013 were identified by searching CINAHL, MEDLINE and Food Science & Technology Abstracts (FSTA) and were included if they were in English and focused on adult oncology patients. Only interventions within the scope of nursing practice were reviewed. RESULTS: Twelve articles were identified for inclusion. Four research groups examined zinc supplementation, with two claiming that zinc supplementation was an effective intervention and two claiming it had no effect on TSA. The remaining research groups examined eight other interventions, with varying results. Marinol, megestrol acetate and Synsepalum dulcificum interventions appear promising. CONCLUSION: Based on this review, there does not yet appear to be an effective approach for preventing or managing TSA in adult oncology patients. Although some interventions show promise, further research is necessary to determine their efficacy.

RESUMO

UNLABELLED: This study of patients under investigation for lung cancer (LC) aims to: 1) examine the prevalence of self-reported taste and smell alterations (TSAs) and their relationships with demographic and clinical characteristics; and 2) explore nutritional importance of TSAs by examining their associations with patient-reported weight loss, symptoms interfering with food intake, and changes in food intake. METHODS: Patients were recruited consecutively during investigation for LC from one university hospital in Sweden. Patient-reported information on TSAs, demographics, six-month weight history, symptoms interfering with food intake, and changes in food intake was obtained. Relationships between TSAs and other variables were examined using two-tailed significance tests. In addition, putative explanatory factors for weight loss were explored in those patients diagnosed with LC, since a relationship between TSAs and weight loss was found in this group. RESULTS: The final sample consisted of 215 patients, of which 117 were diagnosed with primary LC within four months of study inclusion and 98 did not receive a cancer diagnosis. The 38% prevalence of TSAs was identical in both groups, and were generally reported as mild and not interfering with food intake. However, a statistically significant relationship between TSAs and weight loss was found among patients with LC, with a median weight change of - 5.5% and a higher frequency of weight loss ≥ 10%. Patients with LC and weight loss ≥ 10%, had higher frequency of reporting TSAs, of decreased food intake and of ≥ 1 symptom interfering with food intake compared with those with less weight loss. CONCLUSION: TSAs, although relatively mild, were present in 38% of patients with and without LC. Relationships between TSAs and weight loss were found among patients with LC, but not fully explained by decreased food intake. This highlights the complexity of cancer-related weight loss.

RESUMO

PURPOSE: Taste and smell alterations (TSAs) in patients with lung cancer are poorly understood. This study investigates characteristics of TSAs when most severe, reported by patients after starting treatment for lung cancer. METHODS: Data was collected regarding TSAs, symptoms, food intake and nutritional status through structured interviews using the Taste and Smell Survey, the Patient-Generated Subjective Global Assessment and 3-day food diaries. This data derives from a longitudinal project and the interview with each patient when TSAs were most severe was purposefully selected for analysis. RESULTS: Sixty-one of the 89 patients reported TSAs, and the TSAs group were on average younger and more frequently smokers. Thirty-one patients reported symptoms impacting negatively on food intake, with 87 % in the TSAs group and 13 % in the no-TSAs group. Most commonly reported were loss of appetite, nausea and early satiety. Gender differences were seen with more women reporting stronger sensation(s) and more men reporting weaker sensation(s) and other changes. TSAs were described as affecting enjoyment of food and eating. A trend was seen where energy intakes declined with increasing TSAs. Energy intakes in the total study population were below recommended. CONCLUSION: TSAs varied in characteristics and interacted with other symptoms. Gender differences may highlight a need to investigate approaches for identification and management of TSAs in men and women. Patients reported TSAs impacting on food enjoyment, and the hypothesis that patients with higher TSS scores have lower nutritional intakes should be followed up with a larger study in the lung cancer population.

RESUMO

Oat milk was fortified with ß-glucan at a level that attains health benefits and protein at a level equivalent to that of cow's milk. This study aimed to identify consumer perceptions and evaluate the sensory attributes of fortified plain and chocolate oat milks. Oat milk consumers (n = 106) evaluated four samples: C (Control), 0Pro (6.25 g/L ß-glucan), LPro (6.25 g/L ß-glucan and 15.23 g/L oat protein), and HPro (6.25 g/L ß-glucan and 30.45 g/L oat protein); and they completed free-word association (FWA), liking ratings, just-about-right (JAR), check-all-that-apply (CATA), and conjoint analysis (CA). Oat milk was associated with sensory descriptors, environmental sustainability, and health benefits. C and 0Pro products were liked significantly more than LPro and HPro. C and 0Pro oat flavors and thicknesses were rated "just about right" by majority of the participants, while LPro and HPro were rated "too much". Positive CATA attributes were "smooth", "fresh", and "oat-like" while negative attributes were "rancid", "sandy", and "grainy". The CA results showed consumer interest in oat milk fortified with oat protein, containing ß-glucan at a level recommended for health benefits, and with protein levels higher than cow's milk. Based on the results, ß-glucan-fortified oat milk is acceptable while oat protein fortification requires reformulation or substitution with another source.

RESUMO

BACKGROUND: Dietary changes often accompany management of a cancer diagnosis, but how and why patients with colorectal cancer (CRC) make dietary decisions requires further investigation. OBJECTIVE: To learn about patients' food-related beliefs and understand whether and why dietary changes were made by patients starting chemotherapy after a CRC diagnosis. DESIGN: A qualitative semi-structured interview study was conducted as a secondary analysis among a subset of patients with stages II-IV CRC enrolled at baseline in a randomized controlled trial. PARTICIPANTS/SETTING: Twenty-nine patients participated in the interview. Data were collected at the University of Alberta (Edmonton, Alberta, Canada) from 2016-2019 before any trial intervention. QUALITATIVE DATA ANALYSIS: Audio-recorded interviews were transcribed verbatim then coded inductively by two research team members. Qualitative content analysis was applied to capture emergent themes. RESULTS: Patients reported varied degrees of dietary change that stemmed from internal and external influences. Four main themes emerged to describe patients' dietary decisions after a CRC diagnosis: 1) Medical Influences: eating to live; 2) Health Beliefs: connecting lived experiences with new realities; 3) Static Diets: no changes postdiagnosis; and 4) Navigating External Influences: confluence of personal agency and social constraints. CONCLUSION: The extent to which patients altered their dietary choices depended on perspectives and beliefs. These included the degree to which dietary decisions provided some agency (ie, feeling of control) for dealing with physical ramifications of cancer treatment, individuals' personal understandings of healthy foods, and the role of diet in managing their new physical reality postdiagnosis. This information provides registered dietitian nutritionists and health care providers with insight into dietary intentions of select patients being treated for CRC. These findings can guide future research focused on effective strategies for streamlined nutritional support that aligns with patient needs.

RESUMO

Temporal sensory methods can be used to highlight the impact of sodium reduction on the dynamic sensory profile of foods targeted for sodium reduction. Study aims were to compare the temporal sensory attribute profiles of regular and sodium-reduced food products elicited by TDS and TCATA, over single and multiple oral intakes. A total of 20 semi-trained participants evaluated commercially available regular and sodium-reduced canned corn, cooked ham (single intakes), potato chips and cream of mushroom soup (5 intakes) using both TDS and TCATA. Regular and sodium-reduced products differed in not only salty but also other sensory attributes, noticeably dry for chips, sweet for corn, bitter and metallic for ham, thick, creamy, sweet, and starchy for soup. TDS and TCATA provided comparable information for the key sensory attributes characterizing and differentiating the regular and sodium-reduced products. TDS profiled significant differences between samples for a larger number of attributes than TCATA, while TCATA profiles were more consistent across intakes. Multiple intakes changed the duration of attribute dominance but not the number of significantly dominant attributes in TDS profiles. The current findings provide insight for applications of temporal profiling to other food products and development of sodium-reduced foods with attribute profiles acceptable to consumers.

RESUMO

Labelling and information have been shown to increase acceptance of novel food technologies. The novel technology of 3 Dimensional Printing (3DP) of foods is not well known among consumers. The study aim was to investigate the effect of the 3DP label and benefits information on consumer acceptance and perception of plausible 3DP foods. Commercially available foods, such as milk chocolate swirls, gummy candy carrots, and baked potato Smiles®, represented 3DP benefits, and each was evaluated in a sensory panel. Participants rated acceptance and perceived quality after each of three product presentations; first labeled "conventional", then labeled "3D printed", and again labeled 3D printed after information presentation. Participants indicated product preference after the third presentation. Food Technology Neophobia (FTN), attitude, and previous 3DP knowledge were queried. Quality rating of chocolate swirls and gummy candy carrots increased when labeled as 3DP versus conventional; information did not further increase quality ratings. Participants preferred 3DP chocolate swirls and gummy candy carrots to conventional in the final evaluation. Label and information did not change flavor, texture, or overall acceptance ratings for any product. Attitude towards 3DP of foods increased with lower FTN. Future studies could tailor information to consumer interests and knowledge gaps that highlight relevant benefits of 3DP.

RESUMO

BACKGROUND: Dietary fiber is an integral part of a healthy diet, but questions remain about the mechanisms that underlie effects and the causal contributions of the gut microbiota. Here, we performed a 6-week exploratory trial in adults with excess weight (BMI: 25-35 kg/m2) to compare the effects of a high-dose (females: 25 g/day; males: 35 g/day) supplement of fermentable corn bran arabinoxylan (AX; n = 15) with that of microbiota-non-accessible microcrystalline cellulose (MCC; n = 16). Obesity-related surrogate endpoints and biomarkers of host-microbiome interactions implicated in the pathophysiology of obesity (trimethylamine N-oxide, gut hormones, cytokines, and measures of intestinal barrier integrity) were assessed. We then determined whether clinical outcomes could be predicted by fecal microbiota features or mechanistic biomarkers. RESULTS: AX enhanced satiety after a meal and decreased homeostatic model assessment of insulin resistance (HOMA-IR), while MCC reduced tumor necrosis factor-α and fecal calprotectin. Machine learning models determined that effects on satiety could be predicted by fecal bacterial taxa that utilized AX, as identified by bioorthogonal non-canonical amino acid tagging. Reductions in HOMA-IR and calprotectin were associated with shifts in fecal bile acids, but correlations were negative, suggesting that the benefits of fiber may not be mediated by their effects on bile acid pools. Biomarkers of host-microbiome interactions often linked to bacterial metabolites derived from fiber fermentation (short-chain fatty acids) were not affected by AX supplementation when compared to non-accessible MCC. CONCLUSION: This study demonstrates the efficacy of purified dietary fibers when used as supplements and suggests that satietogenic effects of AX may be linked to bacterial taxa that ferment the fiber or utilize breakdown products. Other effects are likely microbiome independent. The findings provide a basis for fiber-type specific therapeutic applications and their personalization.

RESUMO

The oil sands industry is rapidly expanding surface mining and bitumen extraction operations near the Athabasca River in northeastern Alberta, Canada. There are anecdotal comments that the fish from the Athabasca River have an off-taste, implying that the oil sands operations are the cause. This study was done to determine if the taste of wild fishes caught near the Athabasca oil sands was less preferred than the taste of fishes collected from two other river basins in Alberta. In blinded experiments, consumer sensory panels, of 40 to 44 participants, tasted steamed samples of each of three fish species (walleye (Sander vitreus), northern pike (Esox lucius), and lake whitefish (Coregonus clupeaformis)) from three different sources in Alberta (the Athabasca River, Buck Lake, and McGregor Lake). Data analyses showed that there was no evidence from the consumer preference rankings that the taste of the fish from the Athabasca River was preferred less than the taste of fish from two other water bodies in Alberta.

RESUMO

Sugar-reduced chocolates with desirable sensory qualities and sweetness can be created using a 3D printer by layering chocolates with different sugar concentrations. This study aimed to evaluate the temporal sensory profile, perceived sweetness intensity, and acceptance of prototype sugar-reduced and non-sugar-reduced 3D printed chocolates. A consumer panel (n = 72) evaluated the sensory profiles of six-layered chocolates. Sensory profiles were determined by temporal dominance of sensations (TDS), overall sweetness by a five-point intensity scale, overall liking by the nine-point hedonic scale, and differences among chocolates over time were visualized by principal component analysis (PCA). Layering by 3D printing achieved a 19% reduction in sugar without changes in the perceived overall sweetness and overall liking. Layering order of high and low sugar chocolate influenced the perceived overall sweetness and temporal sensory profiles of 3D printed chocolates with different total sugar concentrations. The dominance of attributes associated with milk chocolate was observed to increase sweetness perception while the dominance of attributes associated with dark chocolate was observed to decrease overall sweetness perception. Three-dimensional food printing technology is progressing rapidly, and further sugar reduction could be achieved with refined research methods.

RESUMO

Reduced consumption of conventional red meats due to environmental and health concerns may create interest in less familiar red meats from alternative animal species. The objective of this study was to identify perceptions of three red meats; beef, a familiar meat, and bison and horse meat, less familiar red meat alternatives. A total of 145 western Canadian participants completed an on-line survey that included a free word association task, food variety seeking and food involvement scales, and meat consumption and demographic questions. The free word association yielded 41 word categories of diverging perceptions of the 3 meats. Beef was described with positive sensory attributes and well-liked foods, yet with environmental, ethical and production concerns, reflecting the 'meat eaters' paradox'. Bison was perceived as a lean game meat, suggesting a lack of awareness of current bison production and retail availability. Horse meat was unfamiliar to 80% of the participants. Horse meat was acknowledged to be consumed in other regions, however as a companion animal and pet, the dominant perception of horse meat was that it was unacceptable for eating. Participants were clustered into four groups based on the combined food-related personality traits of variety seeking and food involvement. The high food involvement cluster associated bison with positive eating quality attributes and may be amenable to its consumption when provided with accurate information about bison production.

RESUMO

Oat-based beverages are a nutritious product with the potential to support increased nutrient intake of patients with cancer. The aim of this research was to evaluate the sensory acceptance of oat-based beverages and perceptions of oats among patients with cancer as future vehicles for nutrient delivery. In study 1, three flavors of oat-beverages were well accepted without significant difference in liking among flavors or serving temperature, or between patients with cancer and healthy participants. Patients with cancer more frequently rated the beverages as too sweet compared to healthy participants; flavor intensity was just about right for all participants. In the second study, one of two formulations fortified with protein and fish oil was not different in liking compared to the unfortified chocolate product. Patients associated oat food products with specific oat-based food products and oat health benefits in a free-word association task in the third study. Together, sensory acceptance and the perceived health benefits of oats indicate the potential for oats to be incorporated in fortified and unfortified products tailored for patients with cancer. PRACTICAL APPLICATION: The three studies presented here to assess the sensory acceptance of oat-based beverages and perceptions of oats among patients with cancer demonstrate that oats can be incorporated in fortified and unfortified products tailored for patients with cancer. Inadequate nutrition is highly prevalent among oncology patients and there is a lack of available products targeted to improve their nutritional intake. These findings can support product developers and sensory scientists in the development and evaluation of food products acceptable to this population.

RESUMO

A standard level of sugar addition to bread is 2% (flour base) but sweet baked goods including hamburger buns, hot dog buns and some sandwich bread contain more than 10% sucrose. This study aimed to provide an integrated assessment of different strategies for sugar-reduced bread by using isomaltooligosaccharides (IMO) as bulk sweetening agent, polysaccharide hydrolases to generate sugars from flour polysaccharides, and sourdough. Trained panel sensory analyses of the intensity of sour and sweet tastes were compared to the concentration of organic acids and the sugar concentration of bread. Sourdough fermentation reduced the sweet taste intensity of bread produced with 9% sucrose. This effect was more pronounced with Leuconostoc mesenteroides, which converts fructose to mannitol with concomitant production of acetate. Addition of up to 20% sourdough fermented with Weissella cibaria 10 M, which does not produce mannitol and less acetate when compared to L. mesenteroides, did not substantially reduce the sweet taste intensity. Bread produced with 9% IMO tasted less sweet than bread prepared with 9% sucrose but partial replacement of sucrose with IMO maintained the sweet taste intensity. Addition of 4.5% IMO in combination with W. cibaria sourdough, amyloglucosidase and the fructosidase FruA enabled production of bread with 50% reduced sucrose addition while maintaining the sweet taste intensity. In conclusion, the single use of a sweet bulking agent, of amyloglucosidase or fructanases or the use of sourdough alone, did not maintain the sweet taste intensity of sugar-reduced bread, however, a combination of the three approaches allowed a reduction of sucrose addition without reducing the sweet taste intensity.

RESUMO

Among major contributors of dietary sodium intake, many foods are consumed together with companion foods, specifically condiments and carriers. This study compared sensory profiles and overall liking between commercially available regular and sodium-reduced foods consumed with or without companion foods; and examined changes in sensory profiles and overall liking when foods are consumed in condiment-carrier pairs. Three distinct consumer panels evaluated one of the three condiment-carrier pairs, salsa-corn chips (n = 98, 63% female), ketchup-tater tots (n = 100, 69% female), and soy sauce-cooked rice (n = 98, 70% female). For each panel, consumers evaluated five samples; including the regular and sodium-reduced carriers/condiments alone, the companion food alone, and the regular and sodium-reduced foods each with its companion food. Samples were rated for overall liking (9-point hedonic scale) and the intensity of defining sensory attributes (3-point Rate-All-That-Apply scale). Consumers perceived sensory attribute differences between regular and sodium-reduced corn chips (salty) and soy sauce (salty, sweet), but not ketchup. The presence of the companion food reduced consumer ability to discriminate sensory attributes between regular and sodium-reduced products and changed sensory profiles and liking of the foods. Additionally, consumer heterogeneity in hedonic response identified three consumer segments in each consumer panel. Consumer segments differed in their sensory attribute perception. PRACTICAL APPLICATION: It is possible for the food industry to reduce sodium in a range of companion foods without changing consumer preference. The selection of companion foods is important to consumer evaluation of foods under the context of food pairing; corn chips-salsa and ketchup-tater tots are appropriate food pairs. Future sensory studies on food reformulation toward sodium reduction should target specific consumer segments of product liking and sensory attribute perception, which may in turn be influenced by food consumption frequency.

RESUMO

PURPOSE: Patient-reported questionnaires to assess taste changes (TC) among patients with cancer and the common domains or aspects assessed by those questionnaires are identified in this narrative review. Taste changes are a prevalent symptom experienced by patients with cancer that impact food choice and enjoyment, reduce food intake, and diminish quality of life. Appropriate assessment is essential to detect and manage this symptom. METHOD: A systematic search of relevant databases between 1999 and 2018 yielded 1959 articles; 38 articles were included in the review. RESULTS: Seventeen questionnaires designed specifically to assess patient-reported taste changes among patients with cancer are described in the review. Seven domains were identified among the questionnaires; the most frequently assessed domain was the description of the taste change in 14 questionnaires). Timeframe, scoring, number of items and domains, and item phrasing varied greatly among questionnaires and the approach to domain and item evaluation was inconsistent. Comprehensive questionnaires (n = 7) assessed five or more domains to characterize the taste change experience. The majority of questionnaires have been cited only once or twice. CONCLUSION: Patient-reported taste change assessment in oncology has been achieved by a large number of diverse questionnaires; no standard tool or approach is used. Development of a question bank of validated or standardized taste change modules or items may strengthen the consistency and applicability of research in this area.
