NCT04286386

Brief Summary

This trial examines if a prostate magnetic resonance spectroscopic imaging can be performed on a 3T scanner using an investigational contrast called hyperpolarized 13-C pyruvate for the development of a clinical prostate cancer exam. 3T refers to the strength of the magnetic resonance spectroscopic imaging (MRSI) machine. MRSI is a magnetic resonance imaging (MRI) technique that can show certain chemical differences in healthy and diseased prostate tumor tissue compared to standard multiparametric MRI that may not detect the tumor. Hyperpolarized (HP) 13-C pyruvate is a contrast drug that may help the scanner see the tumor site better during imaging. Hyperpolarization of 13-C pyruvate may allow pyruvate and its metabolites to be detected upon injection, which in turn, allow the prostate cancer to be found and treated.

Outcome Measures

Primary Outcomes (2)

  • Reproducibility of the kpl measurement

    Will be assessed using a test-retest study design. Will be summarized by the intra-class correlation coefficient (ICC). Data from patients at both MD Anderson and University of San Fransisco, San Fransisco (UCSF) will be pooled if possible to increase significance. Bland-Altman analysis will be included if the ICC proves unreliable as a measure of reproducibility. ICC is sensitive to data range; thus, Bland-Altman plot, limits of agreement, repeatability coefficient, and the within-patient coefficient of variation (wCV) may be included as appropriate.

    3 years

  • Reproducibility of the normalized area under the lactate curve (nLac)

    Will be carried out using data from N=40 patients on active surveillance at MD Anderson. Will be summarized by the ICC. Data from patients at both MD Anderson and University of San Fransisco, San Fransisco (UCSF) will be pooled if possible to increase significance. Bland-Altman analysis will be included if the ICC proves unreliable as a measure of reproducibility. ICC is sensitive to data range; thus, Bland-Altman plot, limits of agreement, repeatability coefficient, and the within-patient coefficient of variation (wCV) may be included as appropriate.
