Dexmedetomidine is a centrally acting α2 adrenoreceptor agonist used in perioperative medicine due to its sedative, analgesic and sympatholytic properties. Recently animal data has pointed towards potential role of dexmedetomidine in promoting cancer recurrence and metastasis when used perioperatively especially after breast surgeries. This is because of presence of α2 adrenoreceptors in breast cancer tissue. We reviewed existing literature in which dexmedetomidine was used in cancer surgeries and investigated its role in recurrence and metastasis.
