Ceramidases are ubiquitous amidohydrolases that catalyze the cleavage of ceramides into sphingosine and fatty acids. This reaction exerts a cytoprotective role in physiological conditions, while altered ceramidase activities favour a number of human diseases. Among these diseases, several reports point to important roles of ceramidases, mainly the acid ceramidase, in the initiation and progression of cancer, and the response of tumors to radio- or chemotherapy. Multiple reports confirm the interest of acid ceramidase inhibitors as anticancer drugs, either alone or in combination with other therapies. Sphingolipid metabolism plays a role in hematological malignancies and appears as an interesting target for therapeutic intervention. Although the use of ceramidase inhibitors in chemotherapy of hematologic cancers has not been widely investigated, a number of indirect evidence suggest that inhibition of specific ceramidases could potentiate the effect of drugs in clinical use to treat hematologic malignancies and may afford strategies to combat relapses. The arsenal of ceramidase inhibitors so far available is wide and hopefully, upcoming research will assess the feasibility of this approach.
