Glucose metabolic profiles evaluated by PET associated with molecular characteristic landscape of gastric cancer

Abstract: Background Although FDG-PET is widely used in cancer, its role in gastric cancer (GC) is still controversial due to variable [ 18 F]fluorodeoxyglucose ([ 18 F]FDG) uptake. Here, we sought to develop a genetic signature to predict high FDG-avid GC to plan individualized PET and investigate the molecular landscape of GC and its association with glucose metabolic profiles noninvasively evaluated by [ 18 F]FDG-PET. Methods Based on a genetic signature, PETscore, representing [ 18 F]FDG avidity, was developed by im… Show more

“…Hemoglobin subunit theta 1 (HBQ1) is often used as an indicator related to tumor metabolism. When patients with breast cancer were treated with the combination of bevacizumab and doxorubicin, HBQ1 was often differentially expressed (Borgan et al, 2013;Bae et al, 2022) and IGKV1D-8 was primarily involved in immune response (Gaudet et al, 2011). However, there have been a few reports on AC023449.…”

“…There has also been the suggestion that the differentiated phenotype can alternatively be divided into gastric and intestinal subtypes, related to the cell of origin and the presence of mucin (gastric subtype) [ 17 ]. The metabolic profile of gastric carcinoma is highly variable by FDG PET-CT, and may reflect molecular and histologic growth-type differences in gastric carcinoma [ 18 ]. Whether FDG PET-CT is useful in staging non-GE junction gastric cancer is controversial.…”
