Overview
To learn if participating in a supervised exercise program can help participants with early-stage TNBC who are receiving ICI therapy before undergoing breast surgery.
Description
Primary Objective To evaluate the feasibility of a supervised cardiorespiratory exercise program in patients with clinical stage 2-3 Triple Negative Breast Cancer (TNBC) undergoing neoadjuvant chemotherapy with immune checkpoint inhibitor therapy.
Secondary Objectives To explore the relationship between cardiorespiratory exercise and circulating immune (CD8+ T) cells in the peripheral blood.
