The efficacy and safety of bortezomib-based chemotherapy for immunoglobulin light chain amyloidosis: A systematic review and meta-analysis
2019
Abstract Background The role of bortezomib in the treatment of immunoglobulin light chain (AL) amyloidosis is not well defined. We performed this meta-analysis to evaluate the efficacy and safety of bortezomib-based regimens in patients with AL amyloidosis who are not eligible for or refuse autologous stem cell transplantation. Methods A systematic search of Medline, Embase, and the Cochrane Library was conducted to identify related studies. Results Twenty-four studies with 1238 patients were included. The pooled overall response rate (ORR) and complete hematological response rate (CHR) were 0.72 (95% CI, 0.67–0.77) and 0.35 (95% CI, 0.30–0.40), respectively. Bortezomib significantly improved the outcome of ORR compared to other regimens (RR 1.28, 95% CI, 1.04–1.57, P = .02). Similar results were observed in CHR (RR 1.90, 95% CI, 1.45–2.50, P Conclusions Current evidence indicates that bortezomib-based regimens might be effective and safe therapies for patients with AL amyloidosis. There is a great need to conduct more well-designed randomized controlled trials to provide high-quality evidence.
