Superficial and early cancers of the esophagus.

The following, from the 12th OESO World Conference: Cancers of the Esophagus, includes commentaries on the evolution of Barrett's dysplasia to early cancer; the early detection of esophageal cancer in China; new technologies of treatment for dysplasia; the prognostic value of molecular markers expression in esophageal squamous cell carcinoma; the follow-up schedule after ablation of high-grade dysplasia; intramucosal cancers; and tubular widespread endoscopic esophageal submucosal dissection with high-dose steroid stricture prevention.

CRABP1 provides high malignancy of transformed mesenchymal cells and contributes to the pathogenesis of mesenchymal and neuroendocrine tumors.

CRABP1 (cellular retinoic acid binding protein 1) belongs to the family of fatty acid binding proteins. Retinoic acid binding is the only known functional activity of this protein. The role of CRABP1 in human carcinogenesis remains poorly understood.
