Abstract
Aim. To assess the outcomes of autologous hematopoietic stem cell transplantation (auto-HSCT) in systemic AL Amyloidosis patients treated at the R.M. Gorbacheva Scientific Research Institute of Pediatric Oncology, Hematology and Transplantation.
Materials & Methods. In the period from 2005 to 2022, auto-HSCT was performed in 33 patients with systemic AL Amyloidosis. In 7 of them, auto-HSCT was not preceded by the induction therapy “upfront”. From 2012 all patients received induction therapy prior to transplantation. The median age of patients was 54 years (range 38–68 years); among them there were 17 women and 16 men.
Results. The 3-year follow-up period showed hematological response rate of 76 % (95% confidence interval [95% CI] 50–90 %), heart response rate of 27 % (95% CI 6–55 %), renal response rate of 76 % (95% CI 41–93 %), and hepatic response rate of 26 % (95% CI 8–50 %). The 5-year overall (OS) and progression-free (PFS) survivals were 71 % (95% CI 49–85 %) and 53 % (95% CI 32–71 %), respectively. The OS parameters in the group with delayed auto-HSCT, i.e., after induction therapy, were better than in the “upfront” group: 82 % (95% CI 60–93 %) vs. 43 % (95% CI 10–73 %) (p = 0.03). The OS parameters were affected by health status (p = 0.03), reduced left ventricular ejection fraction < 60 % (p = 0.006), stage of heart disease (p = 0.016), and stage III kidney disease (p = 0.007). The PFS parameters depended on ECOG performance status (p = 0.004) and stage of heart disease (p = 0.041).
Conclusion. The presented data confirm the results of the studies emphasizing the importance of induction therapy prior to auto-HSCT in the treatment of systemic AL Amyloidosis. More stringent parameters of renal function, left ventricular ejection fraction, and ECOG performance status can be used as criteria for auto-HSCT eligibility. Reduced melphalan doses, as conditioning regimen, can be administered to patients with pronounced comorbidity.
