Lymphovascular invasion (LVI) is associated with increased recurrence and metastatic risk in breast cancer. LVI amplifies the impact of genetic mutations on lipid regulation, leading to the deregulation of lipid composition. Currently LVI is estimated using the biopsy sample, while definitive LVI can only be determined after surgery, precluding patients on neoadjuvant chemotherapy or hormonal treatment. Double quantum filtered correlation spectroscopy (DQF-COSY) is a method capable of accurate non-invasive lipid composition quantification. We therefore examined the role of lipid composition using DQF-COSY in differentiating the status of LVI.
