title: [Influence of neoadjuvant therapy on VEGFR-2 levels in tumor and blood serum from breast cancer patients].
abstract: Degree and trends of changes taking place in the angiogenic factors VEGF and VEGFR-2 were studied in cytosols and blood serum sampled from breast cancer patients in the course of neoadjuvant therapy. Such evidence was evaluated vis-alpha-vis basic indices for clinic-morphological features of the disease. The study included 30 cases of locally-advanced tumors. Our results pointed to an influence produced by preoperative therapy on the levels of angiogenic factors both in tumor and serum. However, trends of development of such parameters are different and independent of therapeutic modality. Correlation was established between VEGF and VEGFR-2 levels in residual tumor, on the one hand, and degree of therapeutic pathomorphosis, on the other.
