Prognostic Role of L1CAM in Endometrial Cancer.

The L1 molecule is a cell adhesion molecule (L1CAM) that was originally implicated in neuronal development. In recent years, studies of several large cohorts of patients with endometrial cancer have revealed that L1CAM acts as a poor prognostic factor, in most cases independent of other parameters. It seems to be an important factor, especially in the non-specific molecular profile subgroup (p53 normal expression, MMR proficient, POLE not mutated) of endometrial cancer, and a factor predictive of the response to chemotherapy. This review aims to gather most of the current knowledge regarding this promising prognostic factor.
