THE THYMIDINE KINASE-1(TK-1) AS A POTENTIAL TUMOR MARKER: SERUM LEVELS IN SERUM OF PATIENTS WITH SOLID AND SYSTEM MALIGNANCE NEOPLASMS

Abstract

The review summarizes the results of studies of levels and/or activity in the blood serum of a metabolic marker thymidine kinase-1 (TK-1) of proliferating cells in patients with lymphoproliferative diseases (LPD) and malignant neopasms (NM).Comparison of the data in the literature in some cases have been difficult due to the fundamentally different methods of detection the activity or concentration of TK-1, used by authors, even despite the presence of relatively high (but not absolute) correlation between these parameters (maximum 0.8).Many clinical and laboratory studies have shown levels of correlation and/or TK-1 activity with clinical stages and different types of LPD and solid MN and can serve as a prognostic factor for overall and recurrence-free survival of patients. When solid MN shown that the activity of TK-1 accurately reflects the proliferative status of tumor.A comparison of the dynamics of TC-1 in the process of chemotherapy and its clinical efficacy, different authors have received fundamentally different results: in some cases the marker reduction was associated with treatment efficacy, and in part of publications they show that the clinically relevant effects of the treatment observed increase in the marker after the first chemotherapy.The entire set of received data demonstrates the relevance of the further development of the algorithm use of TK-1 in oncology practice.
