Sialic acid, ferritin and CEA levels in peripheral blood and blood draining from the tumor in breast cancer

Concentrations of total serum N-acetyl-neuraminic acid, carcinoembryonic antigen, ferritin, lactate dehydrogenase, creatine phosphokinase and total proteins were measured in both tumor drainage blood (axillary vein) and in peripheral blood taken during surgery from 44 breast cancer patients. There were no significant differences in any of the markers between mean values in peripheral and tumor drainage blood, between cancer patients and healthy controls, between patients with or without axillary lymph node metastases, or according to the site of breast mass.
