Abstract
PURPOSE: Inherited pathogenic variants in genes encoding the metabolic enzymes succinate dehydrogenase (SDH) and fumarate hydratase predispose to tumor development through accumulation of oncometabolites (succinate and fumarate, respectively; ref. 1). Noninvasive in vivo detection of tumor succinate by proton magnetic resonance spectroscopy (1H-MRS) has been reported in SDH-deficient tumors, but the potential utility of this approach in the management of patients with hereditary leiomyomatosis and renal cell cancer syndrome or Reed syndrome is unknown.
EXPERIMENTAL DESIGN: Magnetic resonance spectroscopy (1H-MRS) was performed on three cases and correlated with germline genetic results and tumor IHC when available.
RESULTS: Here, we have demonstrated a proof of principle that 1H-MRS can provide a noninvasive diagnosis of hereditary leiomyomatosis and renal cell cancer syndrome or Reed syndrome through detection of fumarate accumulation in vivo.
CONCLUSIONS: This study demonstrates that in vivo detection of fumarate could be employed as a functional biomarker.
