Autologous Haematopoietic Stem Cell Transplantation in Multiple Sclerosis: a Review of Current Literature and Future Directions for Transplant Haematologists and Oncologists.

Purpose of Review: We summarise the current development of autologous haematopoietic stem cell transplantation (AHSCT) in treating multiple sclerosis (MS) and discuss future directions for the general neurologist, transplant haematologist and oncologist. Recent Findings: AHSCT was initially performed to treat MS over 20 years ago. Over recent years, the evidence base has grown, especially in relapsing-remitting MS (RRMS), with significant improvements in safety and efficacy through better patient selection, choice of transplant technique and increase in centre experience. Summary: AHSCT is now a treatment option in very carefully selected patients with severe, treatment-resistant RRMS. However, it is important for transplant haematologists and oncologists to work closely with specialist MS neurologists in patient selection, during transplant and in long-term follow-up of patients. Data should be registered into international transplant registries and, ideally, patients should be enrolled on prospective clinical trials in order to build the evidence base and refine transplant techniques.
