ObjectivesThe aim of this study was to evaluate and compare the nutritional status of women with stage I to III breast cancer in the first and third cycles of outpatient chemotherapy and to identify factors associated with it.MethodsThe prospective longitudinal study was conducted at a Reference Hospital for Cancer Care in Brazil and included women aged ≥18 y diagnosed with stage I to III breast cancer receiving outpatient chemotherapy. Assessments were performed during the 1st and 3rd cycles of chemotherapy, including anthropometric measurements, sociodemographic data, clinical information, and quality of life. Nutritional risk was assessed using the NRS-2002.ResultsOverweight was predominant in both chemotherapy cycles. Approximately 6.67% and 10% of patients were at nutritional risk in the 1st and 3rd chemotherapy cycles, respectively. Anxiety/depression was prevalent in the 1st chemotherapy cycle and was significantly associated with nutritional risk (P = 0.002). The variables age in cycle 3 and pain/discomfort in cycle 1 (P = 0.049 and P = 0.043, respectively) showed a significant association with nutritional risk.ConclusionsThis study highlights the complex interaction between nutritional status, neuropsychological symptoms, and sociodemographic characteristics in breast cancer patients during chemotherapy, and underscores the need for personalized interventions to improve oncological care.Copyright © 2024 Elsevier Inc.
