Abstract | BACKGROUND & OBJECTIVE: METHODS: Forty T739 nude mice bearing highly metastatic LA795 cells were randomized into 5 groups: control group, vehicle group, TNP-470 (30 mg/kg) group, CTX (40 mg/kg) group, and combination group ( TNP-470 plus CTX). All mice were killed 3 weeks laterû the subcutaneous tumors were weighted to calculate inhibitory rate. The metastatic tumor foci on lung surface in mice were counted to calculate occurrence rate and inhibitory rate of metastases on lung surface. The microvessel density (MVD) and the expression of tumor metastasis-related factor P-selectin in subcutaneous tumor were detected by immunohistochemistry and analyzed with image analysis system. RESULTS: The inhibitory rate of tumor was significantly higher in combination group (81.5%) than in other groups (P<0.01). TNP-470 plus CTX showed synergetic effect on inhibiting metastasis on lung surface with a Q value of 1.21. The metastatic foci on lung surface were significantly fewer in combination group, TNP-470 group, and CTX group than in control group (1.75+/-1.71, 4.75+/-3.34, and 8.50+/-2.67 vs. 12.13+/-4.02, P<0.05). The MVD and the expression of P-selectin in subcutaneous tumor were also significantly lower in combination group and TNP-470 group than in control group (9.13+/-1.61 and 12.13+/-2.84 vs. 20.50+/-3.12, P<0.01; 5.25+/-2.27 and 7.13+/-3.01 vs. 13.75+/-3.38, P<0.01).
