PURPOSE Taste alterations (TA) and oral discomfort in cancer patients are neglected side effects of the disease and treatments. They contribute to poor appetite, decrease food intake and affect quality of life, leading to adverse outcomes such as malnutrition and depression. The study aimed to explore TAs in relation to other oral conditions causing discomfort in cancer patients. Additionally, the correlation between patients' acidity of saliva and experienced TAs and oral discomfort was evaluated. METHODS A case study including 100 patients diagnosed with cancer receiving chemotherapy or immunotherapy. Data were collected using two questionnaire forms: the Chemotherapy-induced Taste Alteration Scale (CiTAS) and an additional information questionnaire. Saliva samples were collected for each patient and measured with a pocket pH meter. Data were analysed using descriptive statistics, and comparisons were performed using the Kruskal-Wallis H test, Mann-Whitney U test and Fisher's exact test. RESULTS The prevalence of reported TAs was 93%. Patient age, oral discomfort and swallowing difficulty were found to be significant factors for experienced TAs (p < 0.05). No correlation between patients' acidity of saliva and reported TAs and oral discomfort was found. CONCLUSION CiTAS proved to be a convenient tool to collect information about TAs in cancer patients. Using the CiTAS tool, a high prevalence (93%) of reported TAs in cancer patients receiving chemo- or immunotherapy was found. CiTAS provides a fast and cheap recognition of symptoms and causes of TAs that can be addressed.

PURPOSE Taste and smell disturbances in patients affected by cancer are very common, but often under-recognized symptoms. If not addressed properly, they may impact nutritional status, food enjoyment, and quality of life. Treatment tools available for clinicians to manage chemosensory alterations are limited and are often based on personal clinical experiences. The aim of this study was to assess current oncological and palliative care literature through a scoping review, in order to identify av...

Background Taste and smell abnormalities (TSA) commonly occur in cancer and are associated with anorexia, early satiety, malnutrition, weight loss and reduced quality of life. A recent study found a high TSA prevalence in newly diagnosed cancer patients before treatment. This suggests that TSA may originate from the tumour itself. No previous study has examined TSA, both subjectively and objectively, in newly diagnosed, treatment-naive cancer patients. This study aimed to address this gap.

Purpose Taste changes due to chemotherapy may contribute to the high prevalence of malnutrition in cancer patients. It is believed that 50–70% of patients with cancer suffer from taste disorders. The aim of the present study was to analyze the taste alterations in patient population compared with that in controls, also in relation to gender. In this way, it could open to a new approach for a personalized diet to prevent and/or reduce taste alterations and malnutrition in cancer patients.

Purpose Dry mouth is a highly prevalent and significant symptom in patients with advanced progressive diseases. It is a poorly understood area of research, and currently, there is no standardised outcome measure or assessment tool for dry mouth.

Diet and nutrition are critical in health and disease and are highly impacted by the presence and treatment for head and neck cancer (HNC). The purpose of this paper is to present oral examination findings and taste and smell test results in patients during and following HNC. Patients with HNC were evaluated during and following radiation therapy with/without chemotherapy. Oral examination findings including mucositis, saliva, oral hygiene (plaque levels, gingivitis), and taste and smell testing...

Abstract Purpose The chemotherapy-induced taste alteration scale (CiTAS) is a reliable and valid instrument to comprehensively assess patients’ taste alterations in an easy way. We aimed to translate it and test its psychometric properties among Chinese cancer patients undergoing chemotherapy. Method A convenience sample of 227 cancer patients were recruited in a tertiary cancer hospital in Beijing. The Chinese version of the CiTAS (C-CiTAS) was developed via rigorous translation methods. An exp...

Individuals undergoing treatment for cancer can experience changes in taste or smell that are often assumed to affect constructs related to food behavior, although this relationship is rarely measured directly. To ascertain the extent to which measured changes in taste and smell during and after cancer treatment affect food behavior, we conducted a scoping review and completed a comparative analysis for studies that met our criteria, which were: they directly measured cancer patients’ (a) psycho...

Background: Cancer is the leading cause of death worldwide. Of the various therapeutic approaches, chemotherapy is the most widely used treatment. Among the various side effects associated with this treatment, taste alterations (TAs) have received little attention, even though they have a serious impact on the nutritional aspect and quality of life (QoL) of patients. TAs concern 75% of the patients receiving chemotherapy, and this figure is still considered to be underestimatedbeacuse could be d...

Abstract Introduction Taste and smell alteration is a frequent side effect of chemotherapy. However, little is known about their influence on patients’ food behavior and the mechanisms underpinning their occurrence. This lack of clarity is likely due to a series of factors among which heterogeneity in chemotherapy-induced taste and smell modifications may play a prominent role. The present review provides a critical overview of the evidence on the association between taste and smell alterations ...

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.
