Shutter-Speed Model DCE-MRI for Assessment of Response to Cancer Therapy

Wei Huang, Ph.D
Grant Number: U01 CA154602

In clinical oncology and drug development there is genuine need for sensitive and reproducible quantitative imaging methods for early prediction of therapy response and accurate assessment of post-therapy residual cancer. Such methods have the potential to spare non-responding patients from ineffective therapies and associated long and short term toxicity, improve clinical management of individual patient, and accelerate efficacy evaluation of novel therapies. Dynamic-Contrast-Enhanced (DCE) MRI can provide an excellent measure of therapy-induced changes in tumor microvasculature. The Standard-Model (SM) for pharmacokinetic DCE-MRI analysis incorrectly assumes effectively infinitely fast equilibrium inter-compartmental water exchange kinetics and, as a result, often underestimates the pharmacokinetic parameters Ktrans and ve. The Shutter-Speed Model (SSM) accounts for finite water exchange kinetics effects and corrects the imaging biomarker underestimations. SSM parameters have proven more sensitive to vascular changes than the SM parameters. In addition, SSM DCE-MRI allows quantification of a novel imaging biomarker, τi (mean intracellular water lifetime), which is a potential marker of metabolic activity. In Specific Aim 1, applied to a phase I/II clinical trial of soft tissue sarcoma and standard of care neoadjuvant chemotherapy treatment of breast cancer, SSM DCE-MRI is compared with SM DCE-MRI, diffusion-weighted MRI, and tumor size measurement for assessment of therapy response. In Aim 2, the effects of data acquisition and processing schemes, including temporal resolution, measurement of native tissue T1, quantification of arterial input function, and DCE-MRI acquisition duration, on DCE-MRI biomarker values are investigated within the context of therapeutic monitoring. In Aims 1 and 2, pathologic response results are used as endpoints for correlation with imaging results and statistical analyses. In Aim 3, caBIG-compliant software tools are developed that utilize a single and/or a set of imaging biomarkers to aid clinical research.
