BACKGROUNDBisphosphonates have been used to treat many bone diseases in clinic. Bisphosphonates have also been proven useful in the management of bone metastasis in patients with breast and prostate carcinoma as demonstrated in a number of trials in vitro and in vivo, but, it is little known that the effect of bisphosphonates on lung cancer, one of the most common bone metastatic malignant tumors. This study is to investigate the effect of several bisphosphonates on inhibiting proliferation of different lung cancer cell lines in vitro, and to validate whether this inhibitive effect is comprehensive or selective.

METHODSThe cytotoxic effect of bisphosphonates on lung cancer cells and human normal liver cells was determined by sulforhodamine B (SRB) assay.

RESULTSAfter incubation of lung cancer cells with bisphosphonates for 72h, the proliferation was inhibited in different degrees. The inhibiting activity of medronate (MDP) was the lowest, while the activity of ibandronate and incadronate (YM175) was between MDP and alendronate. The effects of bisphosphonates on human normal liver cells were different. The toxicity of MDP, ibandronate and YM175 was low, while alendronate had high toxicity. The sensitivity of lung cancer cells to bisphosphonates was also different. The sensitivity of H446 and SPC-A1 was comparatively lower, while H460 and A549 were more sensitive.

CONCLUSIONSBisphosphonates can inhibit the proliferation of lung cancer cells and human normal liver cells in different degrees. The inhibiting effect is associated with the kind and concentration of bisphosphonates, and also the kind of lung cancer cells.

Objective:To study the anti-tumor efficacy of endostar microbubble combined with focused ultrasound radiation in colon cancer liver metastases.Method:29 mice with colon cancer liver metastasis were randomly divided into four groups. Group 1(8 mice), as the control group. Group 2(7 mice) were treated only with ultrasonic radiation. Group 3 (7 mice) treated with the ultrasonic radiation combined with SonoVue microbubbles without carrying any medicine. Group 4(7 mice), treated with the ultrasonic radiation combined with microbubbles carrying endostar. The mice were sacrificed and the tumor specimens were weighted on the 12 days after ultrasound radiation. Immunohistochemistry was used to assess CD34 expression within the metastatic tumor.Results:The tumor weight in group 4 (0.79±0.49)g was significantly lower than that in group 1 (2.67±0.61)g, group 2 (2.60±0.60)g and group 3 (1.74±0.33)g ( F=20.629, P<0.01). The liver metastatic tumor weight in group 4(0.55±0.16) g was much lower than that in group 1 (1.47±0.22)g, group 2(1.42±0.28) g and group 3 (0.95±0.27)g ( F=23.758, P<0.01). There was no obvious difference among the four groups in the number of nodules of metastatic tumor in liver ( F=0.167, P=0.918). The level of CD34 in group 4 were (8 037±1 708) , significantly lower than that in any other group, ( F=15.779, P<0.01). Conclusion:Endostar microbubble combined with focused ultrasound radiation decreases tumor angiogenesis in liver metastasis, and inhibits the growth of both primary and metastatic tumor.
