Treatment of experimental pancreatic cancer by doxorubicin-, mitoxantrone-, and irinotecan-drug eluting beads

Abstract

Peritoneal carcinomatosis is a common cause of death in pancreatic cancer patients. In this metastatic stage of the disease, few patients show a sustained response to therapy. In the palliative situation, targeted and compartment restricted delivery of drugs offers the opportunity to focus drugs directly to the tumor site, which is a prerequisite for avoiding toxic side effects. Here, we demonstrate the therapeutic efficiency of biocompatible polyvinyl-alcohol hydrogel drug eluting beads (DEBs) containing doxorubicin, mitoxantrone and irinotecan in vitro and in vivo in a syngenic model of experimental pancreatic cancer.
