The study investigates taste disorders that commonly occur during or after cancer treatment, often leading to issues such as malnutrition and treatment discontinuation. Although many non-pharmacological recommendations exist, it is unclear which methods are suitable for which individuals. This randomized study aims to compare the effectiveness of individualized dietary recommendations (Gustabor group) with the current standard of care -general recommendations (Control group). Participants will undergo an objective assessment of taste disorders using taste strips and questionnaires. Based on the results, the Gustabor group will receive both general and specific dietary suggestions. These will be accomapnied by AI-generated recipe suggestions tailored to specific taste disorders (e.g., more cold foods in cases of metallic taste). The control group will receive the current standard: a flyer containing general dietary advice for oncology patients previously shown to be beneficial for managing taste alterations. The primary endpoint is the PG-SGA score within 12 weeks of inclusion.

NOT_YET_RECRUITINGPatient-generated Subjective Global Assessment (PG-SGA) Score
PG-SGA measures four key areas: weight history, including recent unintentional weight loss; the presence of nutrition-impacting symptoms such as nausea, taste changes, and appetite loss; current food intake compared to normal levels; and functional status, which measures the ability to perform daily activities. Based on the responses, a numeric score is calculated, with higher scores indicating a greater risk of malnutrition and the need for dietary intervention.
Time frame: Within 12 weeks of inclusion
Identification of measures that were perceived as helpful
Feedback rating regarding the individual tested measures as helpful / not helpful. Rating using a 3-point scale: "Tried it and it didn't help", "Was somewhat helpful" and "Was very helpful".
Time frame: Within 12 weeks of inclusion
Correlation of PG-SGA progression (PG-SGA Questionnaire) with individual taste perceptions (taste strips), tumor type and ongoing tumor therapy (questionnaire)
Correlation of PG-SGA total score progression with individual taste perception, tumor type, and ongoing tumor therapy. The PG-SGA total score is assessed at both visits using the Scored Patient-Generated Subjective Global Assessment (PG-SGA) questionnaire and reflects the patient's nutritional status. Individual taste perception is measured using the Taste Strips and the corresponding rating scheme provided by Burghart Messtechnik. Tumor type (melanoma, multiple myeloma, gastrointestinal tumors, and urogenital tumors) as well as ongoing tumor therapy (chemotherapy, radiotherapy, and immunotherapy) are assessed using a questionnaire.
