SIALIC-ACID CONCENTRATION IN SERUM AND TISSUE OF ENDOMETRIAL CANCER-PATIENTS

Serum total sialic acid (TSA) level was determined in the group of 45 patients with endometrial neoplasia. Moreover, the sialic acid content in 23 surgically obtained tumor tissue specimens has been estimated. The mean value of serum total sialic acid level of the cancer patients (2.38 mmol/l) was significantly higher (P<0.0001) than the sialic aci d level in the control group (1.52 mmol/l). The elevation of serum tot al sialic acid level was associated with the burden of the tumor (2.30 mmol/l and 2.68 mmol/l for stages I and II + III, respectively). Tiss ue sialic acid content showed no significant differences between early and advanced clinical stage of the disease. (C) 1998 Published by Els evier Science Ireland Ltd.
