[The specificity of expression of molecular biological markers in tumors of the mammary gland].
Data are described on a retrospective immunohistochemical study of the Ki-67, PCNA, Bcl-2, BAX, BclX and VEGF expression in tumors of two groups of patients with breast cancer (BC) and with the favorable and unfavorable clinical courses. A reliably high level of VEGF expression was detected in tumors of patients with an early BC relapse. Apart from VEGF, higher levels of the Ki-67 and PCNA expression were registered in tumors of the discussed patient's category. It can be suggested that the expression parameters of VEGF, Ki-67 and PCNA in the primary tumor can be made use of in evaluating the BD prognostications or describing the features of high-risk groups with a high probability of early disease relapses.
