Feasibility of a Lifestyle Intervention for Women With Triple-negative Breast Cancer Under Neoadjuvant Immunotherapy
About this study
Triple-negative breast cancer (TNBC) is considered a tumor with a high risk of recurrence and metastasis and requires aggressive systemic therapy combining immunotherapy and chemotherapy. If the therapy leads to complete remission (pCR), this is prognostically beneficial for patients. Studies demonstrating the influence of the microbiome on the development of cancer and on the efficacy and toxicity of immunotherapy and chemotherapy underscore the potential of targeted nutritional interventions. Current data from microbiome research indicate that a high-fiber, gut-healthy diet modulates the microbiota in such a way that the response to and toxicity of immunotherapy and chemotherapy could be improved. The aim of this project is to translate these findings into clinical care. The study will investigate whether an online integrative oncology group training program with mind-body elements supports and is feasible for the implementation of a high-fiber diet in patients with TNBC undergoing neoadjuvant immunotherapy and chemotherapy. The program will be compared with a control group that receives a flyer with nutritional recommendations. If the feasibility of this complementary medicine approach can be demonstrated, a confirmatory study is planned to investigate the expected effect on the pathological complete remission of TNBC.
