Influence of a multidisciplinary program of diet, exercise, and mindfulness on the quality of life of stage IIa-IIb breast cancer survivors.

Abstract

193 Background: Integrative oncology has proven to be a useful approach to control cancer symptoms and improve the quality of life (QoL) and overall health of patients, delivering integrated patient care at both physical and emotional levels. The objective of this randomized trial was to evaluate the effects of a triple intervention program on the QoL and lifestyle of women with breast cancer. Methods: Seventy-five survivors of stage IIA-IIB breast cancer were randomized into 2 groups. The intervention group (IG) received a 6-month dietary, exercise, and mindfulness program that was not offered to the control group (CG). Data were gathered at baseline and at 6 months postintervention on QoL and adherence to Mediterranean diet using clinical markers and validated questionnaires. Between-group differences at baseline and 3 months postintervention were analyzed using Student’s t test for related samples and the Wilcoxon and Mann-Whitney U tests. Results: At 6 months postintervention, the IG showed significant improvements versus CG in physical functioning ( p =.027), role functioning ( p =.028), and Mediterranean diet adherence ( p =.02) and a significant reduction in body mass index ( p =.04) and weight ( p =.05), with a mean weight loss of 0.7 kg versus a gain of 0.55 kg by the CG ( p =.05). Dyspnea symptoms were also increased in the CG versus IG ( p =.066). Conclusions: These results demonstrate that an integrative dietary, physical activity, and mindfulness program enhances the QoL and healthy lifestyle of stage IIA-IIB breast cancer survivors. Cancer symptoms may be better managed by the implementation of multimodal rather than isolated interventions.
