OBJECTIVE: To investigate the anti-tumor effect of interventional chemotherapy with liposome doxorubicin for hepatic metastasis of pancreatic tumor in nude mice. METHODS: After the establishment of hepatic metastatic model of pancreatic tumor, the nude mice received various formulations via a spleen injection to imitate the interventional chemotherapy. In each of two following experiments, 42 nude mice were randomly divided into 6 groups. They received liposomal doxorubicin (including high, intermittent and low-dose), free doxorubicin, gemcitabine plus cisplatin and control respectively. In the first experiment, the doses were 6, 3, 1.5, 3, 3 mg/kg and 100 µl 10% glucose for each group respectively. And in the second experiment, 9, 6, 3, 6, 6 mg/kg, and 100 µl 10% glucose respectively. The efficacies of interventional injection of liposomal doxorubicin with different doses were examined in terms of tumor growth retardation for the hepatic metastatic foci of pancreatic tumor. RESULTS: In the first experiment, the difference of median hepatic tumor volume was significant among the three groups of mice receiving liposomal doxorubicin with incremental doses in a dose-dependent manner [high dose: (3 ± 1) mm(3), middle dose: (55 ± 18) mm(3), low dose: (90 ± 23) mm(3), P < 0.05]. The liposomal doxorubicin led to a substantial delay of tumor growth as compared to the free drug or gemcitabine plus cisplatin at the same dose (both P < 0.05). In addition, all animals were well-tolerated...
