Supervised Physical Activity in Young Women With Early Breast Cancer During Neoadjuvant Chemotherpy

• Status: Active, not recruiting
• Trial end date: 2026-12-31

Summary

The main goal of this study is to assess the impact of supervised intense physical activity (IPA) on outcomes of neoadjuvant chemotherapy in young women with breast cancer (YWBC). In this project standard neoadjuvant chemotherapy will be used concordant with summary of product characteristics (SPC). However during treatment (including days of chemotherapy application) an additional modifier of therapy will be carried out in the form of intense physical activity. This strategy is not recognized in SPC. This project aims to improve the results of breast cancer treatment in young women. According to available data, nowadays this subset of breast cancer patients has worse therapy results in comparison to older women. This is partially because of the different tumor characteristics; young women are more likely to present with human epithelial growth factor receptor 2 (HER2) receptor overexpression or with triple negative breast cancer. In the treatment of YWBC, preoperative chemotherapy is most often the first step. This enables the opportunity to assess the effectiveness of additional interventions in a mode it was never tested before. It is believed that physical activity improves the results of breast cancer treatment, however there are only few reports describing its benefit and role in terms of preoperative chemotherapy.

In the current project, the investigators planned to introduce supervised increased physical activity concurrently with neoadjuvant treatment in YWBC at early stage of disease. The main goal of the study is to assess the effect of physical activity on preoperative chemotherapy outcomes. The change of tumor size after neoadjuvant chemotherapy, as well as the impact on Quality of Life (QoL) and Patients' Reported Outcome (PRO) in described above treatment modality. Secondary endpoints are the following: the pathologic Complete Response (pCR), disease free survival after 3 years (3-yr DFS), overall survival (OS), cardiotoxicity of treatment, the effect of physical activity on tumor microenvironment and Ki67 as well as the impact of increased physical activity on further patients' lifestyle changes.
