Core Tip

Core Tip: This is a retrospective study aiming at investigating the relationship between the expression levels of transcriptomic features (eight N6-methyladenosine RNA methylation regulators and five up-regulated microRNAs) and radiomic features extracted from computed tomography images that were significantly associated to clinical outcomes (stage, alcohol history, body mass index) in patients with esophageal cancer . Radiogenomic analysis revealed significant correlations between the expression of the N6-methyladenosine RNA regulators, as well as five up-regulated microRNAs, and several computed tomography radiomic features associated with three investigated clinical outcomes of esophageal cancer patients.
