【 摘 要 】

Abstract Background In 2018, leukaemia accounted for 2.6% of all new cancers, it being the 13th most common cause of cancer and the 10th most common cause of cancer death. Glucocorticoids are commonly used in lymphoid leukaemia treatment, where they are cytotoxic. The aim of this review is to highlight ongoing research of steroid use in myeloid leukaemias. Main text Glucocorticoids increase infection risks in acute myeloid leukaemia, but with adequate antifungal cover, they can help in hyperleucocytic disease. They also show some benefits in sensitising multidrug-resistant AML cell lines to cytotoxic agents, induce differentiation marker expression and can also induce CD38 expression, making AML cells possible targets of daratumumab. Cardiotonic steroids, like digitalis, are being recognised as sensitising AML cells to the chemotherapeutic effects of many cytotoxic agents, primarily by inhibiting efflux pumps, thus minimising AML resistance. Ecdysteroids enhance sensitivity in multidrug-resistant AML, but also in non-resistant AML cell lines, through pathways including the activation of mitochondrial apoptosis. Their anti-apoptotic effects on non-malignant cell lines help their target specificity. Sensitisation is chemotherapy-specific, enhancing the effects of doxorubicin and tubulin inhibitors but increasing resistance to cisplatinum. Short conclusion Cardiotonic steroids and ecdysteroids both show chemosensitisation to the cytotoxic effects of chemotherapy on AML cell lines. It is likely time to consider clinical trials to assess whether these, as well as traditional glucocorticoids, can contribute to the AML armamentarium, particularly in chemo-resistant disease.
