[Tumor markers at the preoperative examination and monitoring of surgical treatment of patients with colorectal cancer].

Comparative analysis of using tumor markers in 159 patients with colorectal cancer was made. Carcinoembryonal antigen, skin reaction of hypersensitivity of slow type with autologous modified lymphocytes and a diagnostic test of tumor growth were used as oncomarkers. Each of three markers may be used for preoperative staging of colorectal cancer, postoperative monitoring of patients and determination of the disease prognosis.

[Staged oncological screening with TG test].

The authors present their analysis of screening methods used for early diagnostics of cancer of various localization and for detection of high-risk individuals. They offer a program of step-by-step screening that makes it possible to cover more population with prophylactic examination and to reduce the need for special examination methods. TG-test is a universal and the most informative blastomatous process indicator at any stage, including the preclinical one.

[Phenotype of peripheral blood lymphocytes in patients with lung cancer].

The expression of surface markers of blood lymphocytes was studied in 32 lung cancer patients. Tumor process involved enhanced expression of the activation markers CD25, CD71 and HLA-DR as well as differentiation antigens CD4, CD8, CD22 and CD16. The expression of the markers was higher than in control, irrespective of stage, localization and histological pattern of tumor.
