Analysis of Changes in Cancer-Related Fatigue of Breast Cancer Patients Receiving an Integrative Medicine Program

Introduction: Cancer-related fatigue (CRF) occurs frequently in breast cancer patients. The aim of this real-world study was to analyze the longitudinal changes of CRF in breast cancer patients receiving an integrative medicine program, which includes the application of non-pharmacological interventions (NPIs) and Viscum album L. (VA) extracts.

Methods: All data were collected from the clinical register of the Network Oncology of a German certified breast cancer center of the Gemeinschaftskrankenhaus Havelhöhe (GKH). Primary breast cancer patients, treated upon initial diagnosis with integrated NPIs, comprising art and exercise therapy, nursing interventions, and educational components, during their hospital stay, and who had answered the German Cancer-Fatigue Scale (CFS-D) questionnaire at first diagnosis and 12 months later, were included. The associations between NPIs and CFS-D changes were analyzed with adjusted multivariable regression analyses, considering received treatment regimens and demographic variables, using the software R.

Results: 231 female breast cancer patients of all tumor stages were evaluated. While chemotherapy exhibited significant severe deterioration, add-on VA applications seem to partially mitigate this impairment on CRF. 36 separate multivariable regression analyses for all NPIs showed that in particular significant associations between CFS-D improvements and the interventions nursing compresses (6 point change; P = .0002; R² = 28%) or elaborate consultations and life review (ECLR) (4 point change; P = .0002; R² = 25%) were observed.

Conclusions: Breast cancer patients benefit from a hospital-based integrative medicine program. To alleviate fatigue symptoms during oncological therapy, an expansion of this concept should be developed in the future.
