Abstract

Osteosarcoma is the most common malignant bone tumour and the second leading cause of cancer‑related death in children and adolescents. Microwave ablation has an excellent therapeutic effect on bone tumours by instantaneously increasing the temperature in the tumour; however, there is a risk of damaging the surrounding healthy tissues by exposure to a high temperature when the treatment power is too large. In the present study, two anti‑tumour reagents, a heat shock protein 90 (HSP90) inhibitor (PF‑04929113) and a transforming growth factor‑β1 (TGF‑β1) inhibitor (SB‑525334) were employed to enhance the therapeutic effect of mild‑power microwave ablation. It was revealed that microwaving to 48˚C combined with HSP90 and TGF‑β1 inhibitors significantly increased the apoptotic rate of VX2 cells. The same results were observed during in vivo experiments using New Zealand rabbits to model osteosarcoma. In addition, the results indicated that the expression of cytochrome c, caspase‑3 and caspase‑9 were upregulated in response to the treatment, which indicated that the mitochondrial apoptotic signalling pathway had been activated. These findings may provide a novel strategy for the development of microwave ablation in osteosarcoma treatment, which could effectively kill tumour cells without damaging the surrounding normal tissues.
