Evidence for a prognostic role of aberrant L1CAM expression has been found in endometrial cancer [13], oral squamous cell carcinoma [14], carcinosarcoma of the uterus [15], cervical cancer [16], serous carcinoma of the ovary [17], adenocarcinoma of the lung [18], ductal adenocarcinoma of the pancreas [19], esophageal squamous cell carcinoma [20], colorectal cancer [21] and neuroblastoma [22]. This evidence concerns the gene L1CAM and endometrial cancer.
