Due to low efficacy of chemotherapy in the treatment of liver cancer, several methods of drug targeting have been investigated. Liposomes designed to carry cytotoxic drugs to the liver are currently under clinical evaluation. While experimental evidence shows promise, this method of drug delivery has several disadvantages that include short shelf life and poor drug delivery into tumour tissue. An alternative strategy for targeted drug delivery involving use of ion exchange microspheres may overcome these limitations while still reducing systemic toxicity and maintaining therapeutic efficacy. The purpose of this study was to determine the relative antitumour efficacy of these two drugs carrying systems in the treatment of liver cancer. Compared to controls, DOX treatment with free drug, liposomes or microspheres significantly reduced tumour growth by 56% (P < 0.001), 51% (P < 0.01) and 79% (P < 0.001) respectively. Furthermore, the DOX-microsphere treatment was significantly better than either of the other DOX treatments (53%, P < 0.05) or the sham-microsphere treated group (64%, P < 0.05). Thus, drug microspheres can increase the anti-tumour efficacy compared to either free or liposomal drug while simultaneously reducing systemic toxicity.
