Özet

Angiogenesis, cellular growth and invasion of a cancer cell are attractive targets for new treatment strategies of malignancies in recent years. The evidences are accumulating that ACE inhibitors and angiotensin II type 1 antagonists could be novel anti-angiogenic, anti-invasive, and even anti-growth agents against neoplastic tissues: The renin-angiotensin system promotes angiogenesis directly or indirectly and growth of neoplastic cell. Some tumors carry angiotensin II type 1 receptors. Angiotensin II antagonists and angiotensin-I-converting enzyme inhibitors have shown some anti-neoplastic actions. Angiotensin II receptor blocker losartan antagonises platelets, which are thought to modulate via vascular endothelial growth factor. They may even protect the patient from the major toxicity of chemotherapy and/or radiotherapy, myelotoxicity, enabling us to give higher doses and end up with higher success rate. We believe that these agents can be useful on clinical grounds and suggest their incorporation into clinical studies. (C) 2002 Elsevier Science Ltd. All rights reserved.
