Autologous stem cell transplantation (ASCT) is standard of care in the treatment concept of adult patients with multiple myeloma (MM), malignant lymphomas (including diffuse large B-cell lymphomas (DLBCL), mantle cell lymphomas, follicular lymphomas or T-cell lymphomas), acute myeloid leukemia (AML) and relapsing germ cell tumors. The number of patients treated with ASCT is steadily increasing, e.g. by +17% alone in Switzerland in the year 2015, to a total of 464 ASCT per year in Switzerland. The Inselspital (University Hospital) in Berne is the leading hospital in Switzerland for ASCT, with 145 ASCT in the year 2015. Among these 145 transplants, 31 patients had DLBCL.
