Reduction of Chemotherapy–Induced Side Effects by Complementary Medicine in Breast Cancer Patients

This clinical investigation was performed to evaluate the benefit of Complementary Medicine (CM) in breast cancer patients undergoing adjuvant Chemotherapy (ChT). Patients and Methods: The patients (n=668) were treated according to international guidelines with adjuvant ChT. As to reduce the side effects, the patients were complementarily treated with a combination of sodium selenite, proteolytic plant enzymes (bromelaine and papain) and Lens culinaris lectin. On Case Report Formulas (CRFs) assessment of side effects of ChT was documented at defined times during adjuvant ChT and additional complementary treatment. Validation was carried out by scoring from 1 (no side-effects/optimal tolerability) to 6 (extreme side-effects/extremely bad tolerability), however, only patients suffering from severe side effects (symptom scores 4 and higher) were enrolled into this investigation. Results: The severity of side-effects of ChT was significantly reduced by complementary treatment. Mean scores of symptoms declined for sleep disorder, fatigue, lack of drive (p<0.05) and for arthralgia, hot flushes, mucosal dryness, nausea, vomiting, diarrhea, loss of appetite, pain of tumour (p<0.001). Conclusion: This investigation confirms benefits of indication-based complementary treatment with the combination of sodium selenite, proteolytic enzymes and Lens culinaris lectin in breast cancer patients, e.g. reduction of side-effects of adjuvant ChT.
