Condition: Hepatocellular Carcinoma (HCC) · Sponsor: Chang Gung Memorial Hospital
Increased pyruvate-to-lactate conversion is a hallmark of HCC metabolism. In parallel, activation of pro-inflammatory immune cells triggers a metabolic switch towards anaerobic glycolysis. Hyperpolarized carbon-13 (13C) pyruvate MRI is a state-of-the-art non-invasive imaging method that offers real-time insights into tissue metabolism. Recent studies have demonstrated its promising potential in predicting responses to radiotherapy and immunotherapy in solid tumors, given the significance of pyruvate as a downstream metabolite in glycolysis. However, its application in assessing treatment response in hepatocellular carcinoma (HCC) patients remains unclear. The establishment of quantitative imaging biomarkers for predicting responses to radio-immunotherapy is an unmet need in the management of HCC patients. While radiotherapy (RT) effectively controls localized tumors through the induction of unrepairable DNA double-stranded breaks (DSBs) and cell death, its therapeutic efficacy on distal, non-irradiated tumor cells is limited, with out-of-field recurrence being a common pattern of failure in HCC patients treated with high-dose irradiation. Atezolizumab (anti-programmed death-ligand 1; anti-PD-L1) in conjunction with bevacizumab (anti-vascular endothelial growth factor; anti-VEGF) has recently emerged as the standard first-line systemic treatment for unresectable hepatocellular carcinoma (HCC). Despite an objective response rate (ORR) of only 27%, the majority of patients succ…
