Bortezomib with dexamethasone as first-line treatment for AL amyloidosis with renal involvement
2016
AbstractAlthough bortezomib has reported efficacy in light chain (AL) amyloidosis, the role of bortezomib in combination with dexamethasone (BD) as the first-line treatment for patients with AL amyloidosis has not been determined. We analyzed the outcomes of 72 consecutive unselected patients, which received primary therapy with BD in a single center. The patients were newly diagnosed with AL amyloidosis with renal (100%), cardiac (72%), hepatic (19%) or nervous system (10%) involvement and underwent a median of 2 (1–6) cycles of BD treatment. A hematologic response was achieved in 75% of the patients within a median period of 2 months, and 45% of those patients achieved a complete response. A renal response was achieved in 50% and 60% of patients at 1 year and 2 years, respectively, and a cardiac response was achieved in 40% and 46% of patients at 1 year and 2 years, respectively. After a median follow-up period of 24 months, the median duration of progression free survival was 45 months, and the estimat...
