Progress of imaging in efficacy evaluation of neoadjuvant chemotherapy for breast cancer / 肿瘤研究与临床

Breast cancer has become the most common malignant tumor among women worldwide. Neoadjuvant chemotherapy (NAC) is a systemic cytotoxic drug therapy for breast cancer before local therapy, which can reduce the tumor staging, improve the pathological complete response rate and breast preservation rate. The therapeutic efficacy of NAC is affected by many factors. Imaging examination is of great clinical value to accurately evaluate the efficacy of patients undergoing NAC. This article reviews the progress of imaging methods such as X-ray, ultrasound, magnetic resonance imaging and PET in evaluating the efficacy of NAC in breast cancer.
