Cancer recurrence monitoring using hyperpolarized [1-13C]pyruvate metabolic imaging in murine breast cancer model

Magn Reson Imaging. 2017 Nov;43:105-109. doi: 10.1016/j.mri.2017.07.014. Epub 2017 Jul 15.


The purpose of this work was to study the anatomic and metabolic changes that occur with tumor progression, regression and recurrence in a switchable MYC-driven murine breast cancer model. Serial 1H MRI and hyperpolarized [1-13C]pyruvate metabolic imaging were used to investigate the changes in tumor volume and glycolytic metabolism over time during the multistage tumorigenesis. We show that acute de-induction of MYC expression in established tumors results in rapid tumor regression and significantly reduced glycolytic metabolism as measured by pyruvate-to-lactate conversion. Moreover, cancer recurrences occurring at the tumor sites independently of MYC expression were observed to accompany markedly increased lactate production.
