Nutritional Status and Information Provided to Polish Cancer Patients Assessed Using the EORTC QLQ-INFO25 Questionnaire.

: Malnutrition in cancer patients may significantly affect various aspects of the quality of life, outcomes, and prognosis, while satisfaction with the information provided may also influence these aspects. This study aims to assess the nutritional status of Polish cancer patients and its association with the level of information received, their potential need for more information, and the resultant quality of life. : A cross-sectional study was conducted in 104 cancer patients. Validated European Organization for Research and Treatment of Cancer questionnaires EORTC QLQ-C30 and EORTC QLQ-INFO25 were used, and nutritional assessment was conducted using Subjective Global Assessment (SGA). : Male patients reported receiving more information than females about the disease, treatment, and care options, as well as greater satisfaction, and a higher overall score. Patients receiving enteral nutrition were more satisfied compared to those not receiving it, even if the scores for the information obtained within the specific areas did not differ, but they still wished to receive more information. Older patients reported higher scores than younger patients, indicating a higher level of information received regarding medical tests and higher satisfaction. The EORTC QLQ-INFO25 global score showed strong or moderate positive correlations with the majority of modules, and the level of information provided significantly influenced satisfaction. : Female patients, those not receiving enteral nutrition, and young patients were less satisfied with the information received, which may negatively influence their quality of life. Effective communication with patients highlights the need for personalized informational support to enhance quality of life.
