The impact of body mass index on the treatment response to neoadjuvant chemotherapy in patients with breast cancer: A systematic review and meta-analysis
Many studies have highlighted that elevated body mass index (BMI) not only correlates with an elevated likelihood of developing breast cancer (BC) but may also influence patients’ responsiveness to therapeutic regimens and long-term survival outcomes. The impact of BMI on therapeutic response to neoadjuvant chemotherapy (NAC) in patients with BC remains inconclusive. This study seeks to evaluate the effect of BMI on treatment response in the BC population undergoing NAC via a meta-analysis, thereby providing evidence-based support for clinical decision-making.
