Research Abstract |
Chemotherapy delivered in nanocarriers has been developed to improve the clinical treatment of solid tumors by achieving high accumulation of chemotherapeutic agents in tumor tissues but limited accumulation in healthy organs via due to the so-called" enhanced permeability and retention(EPR) effect". We showed that low dose metronomic chemotherapy given the damage in endothelial cells of growing tumor vasculature and tumor cells, increased tumor accumulation of nanocarriers as a result of vascular normalization and enlargement of intratumoral space in solid tumors. This strategy may be breakthrough in anti-cancer chemotherapy with nanocarrier-based anticancer drugs against intractable tumors which have lower vascular density and permeability.
