title: [Antigens CA-50 and CA-242 in digestive tract and thyroid neoplasms].
abstract: The aim of the study was to assess the CEA antigen and glycoproteins associated antigen CA-50 and CA-242 in tumours of digestive tract and thyroid gland. 84 patients were the material of the study-33 with digestive tracts' neoplasms (among them 22 cases of large bowel cancer and 11 with cancer of pancreas) and 51 with thyroid neoplasms (30 patients with well differentiated thyroid cancer, 21 follicular adenomas of thyroid). There were assessed level of CA-50 and CA-242 glycoprotein associated antigens. Results were compared with CEA-for digestive tract cancer and Tg levels in thyroid neoplasm respectively. In large bowel cancer (22 cases) there were in 10 patients (45%) with elevated level of CEA, 14 patients with elevated CA-50 (63%) and the same number for CA-242 (14 patients-63%). In cancer of pancreas (total 11 patients) there were CEA elevated level in 3 (27%) patients, CA-50 in 7 (64%) patients and CA-242 in 6 (55%) patients. Patients with well differentiated thyroid cancer (30 cases) revealed elevated level of Tg in 24 (80%) patients, CA-50 in 4 (13%), and CA-242 in 4 (13%) ones. The patients with follicular adenomas (21) had elevated Tg level in 17 (80%) cases, CA-50 in 3 (14%) cases and CA-242 in one patient (4.7%).
