Malignant solid tumors recruit the blood vessel network of the host tissue for
nutrient supply, continuous growth, and gain of metastatic potential.
Angiogenesis (the formation of new blood vessels), vessel cooption (the
integration of existing blood vessels into the tumor vasculature), and vessel
regression remodel the healthy vascular network into a tumor-specific vasculature
that is in many respects different from the hierarchically organized
arterio-venous blood vessel network of the host tissues. Integrative models based
on detailed experimental data and physical laws implement in silico the complex
interplay of molecular pathways, cell proliferation, migration, and death, tissue
microenvironment, mechanical and hydrodynamic forces, and the fine structure of
the host tissue vasculature. With the help of computer simulations high-precision
information about blood flow patterns, interstitial fluid flow, drug
distribution, oxygen and nutrient distribution can be obtained and a plethora of
therapeutic protocols can be tested before clinical trials. In this review, we
give an overview over the current status of integrative models describing tumor
growth, vascular remodeling, blood and interstitial fluid flow, drug delivery,
and concomitant transformations of the microenvironment. WIREs Syst Biol Med
