Abstract

Iressa, a new molecular targeting medicine, has some effects on advanced non-small cell lung cancer, but its effect on hepatocellular carcinoma (HCC) has seldom been reported. This study was to observe the efficacy and adverse effect of Iressa on HCC Hep-3B and HepG2 cell xenografts in nude mice. The nude mice with Hep-3B and HepG2 cell xenografts were randomized into control group (8 mice), low-dose group (8 mice), and high-dose group (8 mice), and received daily oral gavage of 5% glucose solution, 100 mg/kg Iressa, and 200 mg/kg Iressa, respectively, by 5 days each week for 3 weeks. The mice were killed 2 days after treatment. Inhibitory rate (IR) of tumor growth was calculated. Tumor volume, mice weight, and spleen index (SI) were compared between groups. Body weight and tumor volume of the mice were caparable before treatment. IRs of Hep-3B cell xenograft growth were 32.77% in low-dose group and 46.99% in high-dose group; IRs of HepG2 cell xenograft growth were 68.57% and 75.24%, respectively. Body weight and SI of nude mice with either Hep-3B or HepG2 cell xenografts were significantly lower in high-dose group than in control group, but no obvious difference was observed between low-dose group and control group. Iressa has...Continue Reading
