The enhanced permeability and retention (EPR) effect is a controversial concept by which molecules of certain sizes (typically liposomes, nanoparticles, and macromolecular drugs) tend to accumulate in tumor tissue much more than they do in normal tissues. The general explanation that is given for this phenomenon is that, in order for tumor cells to grow quickly, they must stimulate the production of blood vessels. VEGF and other growth factors are involved in cancer a… WebIntroduction. The enhanced permeability and retention (EPR) effect was defined by Matsumura and Maeda as an intratumoral phenomenon resulting from the increased leakiness of newly forming tumor vessels as well as decreased lymphatic drainage. 1 Therapy based on the EPR effect has not been the expected success, 2 possibly due to …
