The water-perfusable tissue fraction of colorectal cancer metastases is increased by the selective PDGF-receptor inhibitor imatinib but not the IL-1 receptor antagonist anakinra, a study using serial dynamic 15O-water PET.
High interstitial fluid pressure (IFP) in colorectal cancer metastases may decrease the uptake and, thus, the effects of anti-tumor drugs. Imatinib, a selective inhibitor of PDGF receptors, and anakinra, an interleukin-1 receptor antagonist, respectively, increase drug uptake and/or decrease IFP in preclinical models of carcinoma. Drug-induced decrease in IFP in human metastases has not been objec
