High FDG uptake on PET is associated with negative cell-to-cell adhesion molecule E-cadherin expression in lung adenocarcinoma

E-cadherin is a main cell-to-cell adhesion molecule. A negative expression of E-cadherin correlates with distant metastasis in lung cancer. Recently, it was reported that there is an association between FDG up...
