Outcomes of patients with multiple myeloma undergoing autologous transplant with suboptimal pretransplant response

Abstract

There are scarce data in the literature focusing on newly diagnosed multiple myeloma (NDMM) patients who undergo autologous haematopoietic cell transplantation (autoHCT) after achieving suboptimal response to induction. To address this, we performed a retrospective, single-centre analysis of patients with NDMM who underwent upfront autoHCT between 2005 and 2021 with a pretransplant response of less than very good partial response ( < 0.001 and HR 0.51, p < 0.001) were associated with superior PFS and OS respectively. In conclusion, NDMM patients who received upfront autoHCT with a pretransplant response of 3 years and median OS of >8 years. Post-transplant maintenance further improved survival outcomes.
