Conditions studied: Breast Neoplasms
In brief
This study will determine how the intestinal microbiome differs between patients with obesity and early triple-negative breast cancer who achieve a pathologic complete response from preoperative anti-PD-1 immunotherapy (pembrolizumab) versus patients who do not.
