title: [Clinical effectiveness of degradable starch microspheres (DSM) in patients with liver cancer].
abstract: Recently, degradable starch microspheres (DSM) have become available for use in patients with liver cancer in Japan. When DSM combined with a cytotoxic drug are infused through the hepatic artery, the steep drug concentration gradient to the tumor tissue results in a higher tissue drug concentration, which may elicit an increased antitumor response by blocking regional blood flow. Furthermore, the reduced systemic exposure of a coinjected drug can be translated into an increased regional extraction ratio due to blood flow reduction. DSM is infused via a catheter connecting to a subcutaneously implanted reservoir in outpatients. Pain is experienced by all patients. Other frequently observed adverse reactions are nausea and vomiting. However, these symptoms improve within a few hours. These observations indicate that intra-arterial chemotherapy combined with DSM may provide a more potent anticancer effect than a cytotoxic drug alone.
