This project seeks to develop a quantitative imaging biomarker for evaluating and monitoring treatment response in ovarian cancer metastases and assess its potential in monitoring treatment response. This will involve standardising DW-MRI for the abdomen and pelvis across multiple centres and platforms, assessing reproducibility of the measurement in patients planned for neoadjuvant chemotherapy and assessing its utility as an early response biomarker in patients with platinum-sensitive relapse due to receive therapy with carboplatin. Scanning measurements will be correlated with histopathological markers in tumour samples in order to link the biomarker with response mechanisms.
Development of a Quantitative Imaging Biomarker for Evaluating Ovarian Cancer Metastases and Assessment of its Potential in Monitoring Treatment Response. [ Time Frame: 4.0 years ]
Diffusion-weighted magnetic resonance imaging (DW-MRI) for visualising peritoneal metastases will be developed.Reproducibility will be assessed in a multi-centre setting across multiple vendor platforms and field strengths by comparing 2 baseline scans per person and plotting absolute difference in ADC against mean of the 2 measurements.Biological validation will be achieved by correlating scan data (ADC change) following chemotherapy with histology of the tumour(amount of cell death) at surgery.
Biospecimen Retention: Samples With DNA
Tumour samples taken at surgery for histological analysis
