Test Description and clinical significance
Disease:
Adenocarcinoma, excludig mesothelioma
BG8 Lewisy, also known as Lewisy Blood Antigen or simply BG8, is a blood group antigen that has been identified in many studies as a potential marker for differentiation between pulmonary adenocarcinoma (PACA) and epithelioid mesothelioma (EM). It has been reported that sensitivity of non-mesothelial antigens for adenocarcinoma is organ-dependent. When attempting to differentiate epithelioid mesothelioma from adenocarcinoma, BG8 Lewisy performed at a sensitivity of 98% in the breast cancer group, and 100% in the lung cancer group.
