Tumor-associated neoangiogenesis has recently become a suitable target for antineoplastic drug development. In this overview, we discuss specific drug-associated hemostatic complications, the already known pathogenetic mechanisms involved, and the effect of varying antithrombotic strategies. Multiple agents with angiogenic inhibitory capacity (thalidomide, lenalidomide, bevacizumab, sunitinib, sorafenib, and sirolimus) have obtained US Food and Drug Administration approval, and many others have entered clinical trials. Arterial and venous thromboembolism and hemorrhage have emerged as significant toxicities associated with the use of angiogenesis inhibitors. We present a detailed analysis of the literature on thrombotic complication of antiangiogenic drugs. Close attention to hemostatic complications during antiangiogenic treatment is warranted. Further studies are required to better understand the pathophysiologic mechanisms involved and to define a safe prophylactic strategy.

    • "The risk is additionally increased if chemotherapy is combined with steroids (Shen et al, 2011) or erythropoietin (Bennet et al, 2008). The inhibitors of angiogenesis (thalidomide, lenalidomide, bevacizumab, sunitinib, sorafenib, and sirolimus) used as novel antineoplasic therapy are associated with an increase in arterial and venous thromboembolism and hemorrhage (Zangari et al, 2009). Gemcitabine is a deoxycytidine analogue related to cytarabine, that has been shown to improve evolution in patients with advanced PC. Deep venous thrombosis was found in one study in 3.2% of patients treated with gemcitabine (Kaye,1994). "

    • "As a result, abnormal apoptosis of endothelial cells leads to the exposure of highly prothrombotic basement membrane (Zangari et al, 2009). In addition, the prothrombotic effect may result from reduced levels of prostaglandin 1-2 and NO, leading to increased platelet activation (Zangari et al, 2009). Table III. "

    ABSTRACT: The pathophysiology of pulmonary hypertension (PHT) in sickle cell disease (SCD) is probably multifactorial. Soluble fms-like tyrosine kinase-1 (sFLT-1) is a member of the vascular endothelial growth factor receptor (VEGFR) family. By adhering to and inhibiting VEGF and placenta growth factor, it induces endothelial dysfunction. We sought to evaluate the association of sFLT-1 with clinical complications of SCD. We confirmed that sFLT-1 was significantly elevated in SCD patients compared to healthy, race-matched control subjects. The level of sFLT-1 was significantly higher in patients with PHT, but no association was observed between sFLT-1 and the frequency of acute pain episodes or history of acute chest syndrome. sFLT-1 was correlated with various measures of haemolysis, erythropoietin and soluble vascular cell adhesion molecule-1. By inducing endothelial dysfunction, sFLT-1 may contribute to the pathogenesis of SCD-associated PHT, although this effect does not appear to be independent of haemolysis.

    ABSTRACT: Inhibition of tumor angiogenesis has become an attractive target of anticancer chemotherapy. However, drug resistance and cytotoxicity against non-tumor associated endothelial cells limit the long-term use and the therapeutic effectiveness of angiogenesis inhibitors, thus increasing the necessity for the development of multi-target agents with minimal side effects. Traditional Chinese medicine (TCM) formulas, which have relatively fewer side effects and have been used clinically to treat various types of diseases, including cancer, for thousands of years, are considered to be multi-component and multi-target agents exerting their therapeutic function in a more holistic way. Hedyotis Diffusa Willd (EEHDW) has long been used as an important component in several TCM formulas to treat various types of cancer. Although recently we reported that EEHDW promotes cancer cell apoptosis via activation of the mitochondrial-dependent pathway, the precise mechanism of its tumoricidalactivity still remains to be clarified. In the present study, we investigated the angiogenic effects of the ethanol extract of EEHDW. Cell cycle analysis was perfomed using flow cytometry. Cell viability was analyzed using MTT assay. We found that EEHDW inhibited angiogenesis in vivo in chick embryo chorioallantoic membrane (CAM). In addition, we observed that EEHDW dose- and time-dependently inhibited the prolife-ration of human umbilical vein endothelial cells (HUVEC) by blocking the cell cycle G1 to S progression. Moreover, EEHDW inhibited the migration and tube formation of HUVECs. Furthermore, EEHDW treatment down-regulated the mRNA and protein expression levels of VEGF-A in HT-29 human colon carcinoma cells and HUVECs. Our findings suggest that inhibiting tumor angiogenesis is one of the mechanisms by which EEHDW is involved in cancer therapy.
