BACKGROUND: Aggressive surgical removal of the primary tumour is the preferred treatment, but with tumour progression, some tumours cannot be completely removed surgically. Anaesthetics are administered to facilitate surgery. However, anaesthetics act as a potential factor in tumour recurrence or metastasis. MATERIALS AND METHODS: Normal breast cells and cancer breast cells were treated with different doses of muscle-relaxant anaesthetics. The effects on breast cancer cell invasion, adhesion and migration of these anaesthetics were then investigated using in vitro models. RESULTS: With increasing dose of rocuronium bromide and suxamethonium chloride CRS, the number of MCF-10A and MCF-7 cells, but not that of MDA-MB-231 cells, decreased. There was almost no difference in the number of cells when the three cell lines were treated with different doses of vecuronium bromide. The study also demonstrated that rocuronium bromide promoted the invasion, adhesion and growth of MDA-231 cells, while suxamethonium chloride CRS had no effect. Interestingly, vecuronium bromide did not affect the motility and invasion of breast cancer cells significantly. CONCLUSION: An understanding of the effect of anaesthetics and their impact on tumour metastasis is important, thus using an appropriate aesthetic strategy could improve long-term survival in some patients.
