von Willebrand factor antigen levels in plasma of patients with malignant breast disease

Abstract: von Willebrand factor (vWF) is a protein that mediates platelet adherence to the subendothelium during primary hemostasis. High plasma vWF concentrations have been reported in patients with various types of cancer, such as head and neck, laryngeal and prostatic cancer, probably representing an acute phase reactant. In the present study we determined the plasma levels of vWF antigen (vWF:Ag) by quantitative immunoelectrophoresis in 128 female patients with breast cancer as well as in 47 women with benign breast… Show more

“…In our study, patients with GBM had higher plasma VWF:Ag levels than those with benign expansive brain lesions. At variance with many of these, we took patients with benign brain expansive lesions as controls rather than healthy subjects considering that VWF:Ag usually raise in all patients with both benign and malignant neoplastic diseases 28, so rendering the finding of significantly higher levels in malignant gliomas more robust.…”

“…Cancer patients have been shown to have higher VWF levels and lower ADAMTS‐13 levels than the general population, often also in a stage‐dependent intensity …”

“…O aumento dos níveis séricos de fvW é associado com maior risco de eventos clínicos da doença cardiovascular, principalmente tromboembolismo, infarto agudo do miocárdio e acidentes vasculares cerebrais 12 . Níveis elevados de fvW foram também descritos em alguns tipos de cânceres (cabeça e pescoço, próstata) e bem correlacionados ao câncer de mama 13 . Em um estudo foi comparada a dosagem de fvW em 128 pacientes com câncer de mama, em 47 pacientes com doença mamária benigna e em 27 controles.…”

“…Em um estudo foi comparada a dosagem de fvW em 128 pacientes com câncer de mama, em 47 pacientes com doença mamária benigna e em 27 controles. A média e desvio padrão da dosagem de fvW no grupo controle foi de 130,6 ± 45 U/dl, nas pacientes com doença benigna 148,4 ± 59 U/dl e nas com câncer 170,7 ± 78 U/dl, sendo significativa a diferença encontrada entre as pacientes com câncer e os outros dois grupos 13 . Durante a fase ativa da angiogênese tumoral, são sintetizados fator de crescimento do endotélio vascular (VEGF) e fator de crescimento de fibroblasto (FGF-2), que contribuem para a proliferação e diferenciação do endotélio vascular, o maior produtor de fvW, resultando em aumento dos níveis séricos de fvW 14 .…”
