An Investigation Into Dielectric Testing for the Evaluation and Characterisation of Breast Tissue Using a Novel Time-Domain Bioimpedance Tool

Sponsor: Zedsen Limited

Summary

Capacitance measures a material's ability to store the movement of electrical energy in the electric field. Different of the human body are known to have different capacitance values. Research is looking into utilising capacitance differences, using a method called bioimpedance, to detect signatures of cancer. Breast cancer is the most common type of cancer in women globally, and the bioimpedance of healthy breast tissue is different to cancer tissue. Breast tissue is accessible by non-invasive means and has well-established clinical tools for cancer detection. However, results from studies vary and research is needed to understand how bioimpedance can be used in cancer research and the development of less invasive detection tools. Zedsen Limited developed the ZedScanner capable of measuring capacitance. Previous versions of the Zedscanner were investigated in a proof-of-concept study and shown to be safe to use. The proposed study aims to establish the feasibility, safety, and performance of the updated ZedScanner in classifying healthy, benign, and cancer tissue. We will recruit 220 women attending a breast appointment at Charing Cross Hospital (40 without lesions, and 90 with malignant lesions and 90 with benign lesions). Invited women will have their breasts scanned after routine imaging and before any biopsy. Data will be fed into AI algorithms to enhance the ZedScanner performance. The ZedScanner's ability to measure capacitance of tumours that are being treated with neoadjuvant chemotherapy will be explored. Twenty women with a malignancy who consent to being followed up over their treatment course, will have 2 additional scans. Finally, participants will be asked to share their experience of the ZedScan in a questionnaire. Results from this study can further our understanding on how capacitance and such devices can be used in breast cancer clinical management.
