The purpose of this study is to examine whether a nutrition and exercise program can improve pathologic complete response (pCR) in women with triple-negative breast cancer (TNBC) receiving chemo-immunotherapy before surgery. Pathologic complete (pCR) response means that no cancer in the breast is seen after chemotherapy.
Women with stage II-III triple-negative breast cancer (TNBC) undergoing neoadjuvant chemo-immunotherapy will be enrolled in the study. Following screening, consent, and baseline assessment, participants will be randomized to either the intervention group (nutrition and exercise counseling) or the usual care group. Participants randomized to the intervention group will complete weekly remote sessions with the interventionist throughout the duration of chemotherapy. Each counseling session will last about 30 minutes and will be conducted remotely. The exercise regimen is home-based. Study activities include completing surveys and attending two in-person study visits, each of which will include a blood draw, a 6-minute walk test to assess aerobic capacity and endurance, and a Dual Energy X-Ray Absorptiometry (DXA) scan to measure body composition. The primary outcome is the pathologic complete response. Researchers will also compare the exercise and nutrition program to usual care to determine if the program improves residual cancer burden, symptoms related to cancer treatment, body composition, and blood biomarkers.

RECRUITINGPathologic Complete Response (pCR)
Pathologic Complete Response (pCR) is defined as having no invasive residual disease in the breast or regional lymph nodes after completing neoadjuvant chemotherapy (ypT0 ypN0 or ypT0/is ypN0)
Time frame: Post breast cancer surgery, an average of 6 months
Residual Cancer Burden (RCB)
Residual Cancer Burden (RCB) is a continuous pCR measure.
Time frame: Post breast cancer surgery, an average of 6 months
