Abstract

We appraised Warburg effect through analysis of mitochondrial DNA (mtDNA) copy number and maximum standard uptake value (SUVmax) of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) scan and their alterations in esophageal squamous cell carcinoma (ESCC). Later T-status and longer longitudinal tumor length were associated with lower mtDNAESCC copy number (p < .05) but higher SUVmax-ESCC (p < .05), respectively. Lower mtDNAESCC copy number correlated with higher SUVmax-ESCC, reciprocally (p < .05). ESCCs expressing mutant p53 protein had lower mtDNAESCC copy number (p = .056) but higher SUVmax-ESCC (p = .046). We conclude that mutant p53 protein may be involved in the Warburg effect of ESCC.
