Popis: TPS12138 Background : Cardiotoxicity is a significant challenge associated with common first-line breast cancer (BC) chemotherapy (CTx) treatments including anthracyclines (AC) and targeted therapies, such as anti-Her-2 therapy. For targeted therapies, cardiac complications typically resolve once treatment is completed or stopped. For ACs, treatment may lead to permanent long term cardiac damage, and elevated risk for major adverse cardiovascular events (MACE). Black/African American (B/AA) women are at higher risk for AC-based cardiotoxicity compared to Non-Hispanic White (NHW) women. To date, most efforts have targeted managing and defining mechanisms of large vessels and cardiac damage. However, impaired microvascular function, a powerful but clinically underused predictor of future MACE, may also be implicated. Extensive evidence shows that exercise interventions reduce systemic inflammation and possibly MACE. However, few cardio-oncology studies have utilized exercise to mitigate cardiotoxicity, and none have quantified microvascular endothelial function. A further gap in cardio-oncology research is a paucity of studies focused on understanding and addressing disparities. This research project aims to 1) test the feasibility and efficacy of an exercise intervention designed to mitigate the effects of CTx, Take Charge during Treatment (TCT) and 2) examine the influence of socio-ecological factors on endothelial function in response to an exercise intervention. Methods: B/AA (n=50) and NHW (n=50) women diagnosed with non-metastatic BC, scheduled to receive AC and/or anti-HER-2 therapy, will be recruited and randomized to participate in the TCT intervention or usual care (NCT05223322). TCT is a virtual exercise coaching program with weekly coaching sessions, six of which include supervised exercise. Assessments to assess socio-ecologic and vascular outcomes are presented in the Table. Assessments will be completed prior to treatment (T1), after treatment completion (18-24 weeks, T2), and 12-months post treatment (T3). Clinical trial information: NCT05223322. [Table: see text]
