Patients with L1CAM positive tumours presented more often at the highest FIGO stage (31.1% vs 6.9%, P=.023) and if they had lymph node metastasis, it was more likely to be bilateral (31.3% vs 8.0%, P=.029) and with extracapsular growth (37.5% vs 12.6%, P=.024). This evidence concerns the gene L1CAM and metastatic malignant neoplasm in the lymph nodes.
