A Prospective Study to Evaluate FDG-PET, Breast MRI, and Breast Ultrasonography in Monitoring Tumour Responses in Patients With Locally Advanced Breast Cancer (LABC) Undergoing Neoadjuvant Chemotherapy

The overall goal of this study is to determine how FDG-PET, breast MRI and breast ultrasound can be incorporated into the assessment of treatment responses in women with LABC undergoing neoadjuvant chemotherapy. A prospective cohort study will be conducted evaluating the ability of FDG-PET, breast MRI and breast ultrasound to detect the presence of residual tumour in patients with LABC who have completed treatment with neoadjuvant chemotherapy prior to mastectomy.
