The Potential Influence of Dietary Counseling on Nutritional Status and Dietary Supplement Consumption in Breast Cancer Patients: A Pilot Study.

INTRODUCTION

Cancer, in particular breast cancer, is one of the leading causes of death among women. Good nutritional status contributes to the efficacy of treatment and recovery, and nutritional interventions can minimize the adverse effects of cancer therapy.

AIM

The aim of this study was to describe the potential role of dietary counseling in breast cancer patients. The impact of nutritional advice on the nutritional status of patients, the use of dietary supplements, and the knowledge of phytoestrogens were assessed.

MATERIALS AND METHODS

The study was conducted between April and July 2016 in the Lublin Oncology Center on a group of 173 female patients undergoing breast cancer treatment. The patients filled out a questionnaire containing 34 open-ended and closed-ended questions. The collected data were processed in Excel and Statistica 5.0 programs, and the results were regarded as significant at P < 0.05.

RESULTS

The mean age of the evaluated patients was 66.8 ± 11.3 years. The duration of disease was significantly correlated with the patients' nutritional status expressed by the body mass index (P = 0.0368). The main sources of knowledge about nutrition in cancer care were nurses (29.71%), physicians (12.31%), and nutritionists (13.78%). Patients who received nutritional advice had significantly greater knowledge about phytoestrogens (P = 0.0001), and they were of the opinion that a diet rich in phytoestrogens was safe (P = 0.001). More than 85% of the polled subjects used dietary supplements during treatment, and 2/3 of them did so without professional advice. In this study, 73.07% of the respondents regularly monitored their body weight. Patients who did not receive dietary advice less frequently informed their physician about weight changes.

CONCLUSIONS

The nutritional status of patients was correlated with access to nutrition and dietary advice during illness. The risk of malnutrition was minimized when patients received and understood educational materials. The patients who did not receive dietary advice more frequently overdosed on dietary supplements. Phytoestrogens were more widely used by patients who regularly attended a dietitian.
