Angiogenese-Inhibitoren und Radiotherapie


Riesterer, O (2012). Angiogenese-Inhibitoren und Radiotherapie. Praxis, 101(16):1031-1037.

Abstract

Tumor angiogenesis, i.e. the formation of new blood vessels, is a promising therapeutic target. Whereas angiogenesis inhibitors (AI) are selectively aimed against the tumors' vascular system, irradiation targets both, tumor cells and tumor vasculature. Biological interaction of both modalities has been shown on the level of tumor endothelial cells and the microenvironment. The clinical testing of this novel combined treatment strategy so far has been hindered, because AI intuitively increase tumor hypoxia and hypoxic tumors are radio-resistant. However preclinical studies demonstrate that AI can even induce vascular normalization. Furthermore, consolidation therapy with AI after radiotherapy is a promising approach due to the specific biology of irradiated tumor bed. Based on these findings clinical studies are now increasingly been conducted.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
