Management
of renal cell carcinomas (RCCs) is reliant on imaging, which cannot reliably differentiate malignant RCCs from benign renal tumors. RCCs
exhibit increased glycolysis, resulting in elevated lactate production. This can
be used to differentiate RCCs from benign renal tumors using the hyperpolarized
13C MRI, a molecular imaging technique that can measure real-time
dynamic pathway-specific metabolic fluxes. Our aim was to investigate the pyruvate-to-lactate
flux in living patient-derived renal tissues using hyperpolarized [1-13C]pyruvate.
We have shown that rapid lactate efflux is a distinguishing feature of clear
cell RCCs (which comprise 90% of all RCCs), and can be detected using hyperpolarized
[1-13C]pyruvate.
