Another study regarding L1CAM expression (technical details not provided) was conducted in 392 low-grade (endometrioid adenocarcinoma, grade 1 and 2) and 183 high-grade (grade 3 endometrioid adenocarcinoma, serous and clear cell carcinoma) cases, showing the independent significance of L1CAM expression in predicting recurrence only in the high-grade group in the multivariate analysis integrating several parameters but not the molecular classification [70]. Here, L1CAM is linked to endometrioid adenocarcinoma.
