Vascular endothelial growth factor (VEGF) levels and mutation of the BRCA1 gene in breast cancer patients.

The aim of the study was to compare VEGF serum levels in breast cancer patients with and without BRCA1 gene mutation. We enrolled 80 patients, 22 premenopausal and 58 postmenopausal. We found statistically significant lower levels of VEGF in patients with BRCA1 gene mutation as compared with breast cancer patients without this mutation.
