Acute Complications After High-Dose Chemotherapy and Stem-Cell Rescue in Pediatric Patients With High-Risk Neuroblastoma Treated in Countries With Different Resources

J Glob Oncol. 2018 Sep;4:1-12. doi: 10.1200/JGO.17.00118.

Abstract

Purpose: High-dose chemotherapy with autologous stem-cell rescue (SCR) is a key component of high-risk neuroblastoma (HRNB) therapy. Carboplatin, etoposide, and melphalan (CEM) or busulfan and melphalan (Bu/Mel) are the most evaluated, effective high-dose chemotherapy for HRNB on the basis of results from major cooperative group studies. Toxicity profiles vary between these regimens, and practice variation exists regarding the preferred high-dose therapy (HDT). We sought to evaluate the safety of HDT and autologous SCR for HRNB in a resource-limited country (Egypt) compared with the resource-rich United States.

Patients and methods: We performed a retrospective comparative review of single CEM-based HDT/SCR outcomes through day 100 for HRNB at the Fred Hutchinson Cancer Research Center (FH) in the United States (2005 to 2015) versus Bu/Mel-based HDT at El-Sheikh Zayed Specialized Hospital (SZ) in Egypt (2009 to 2015).

Results: Forty-four patients at FH and 77 patients at SZ were reviewed. Pretransplant hepatic comorbidities were significantly higher at SZ (29 of 77 v nine of 44; P = .05), with 19 of 77 patients at SZ having hepatitis infection. Engraftment was delayed after SZ-Bu/Mel therapy compared with FH-CEM therapy for neutrophils (median 12 days v 10 days, respectively; P < .001) and platelets (median 20 days v 18 days, respectively; P < .001). Sinusoidal obstruction syndrome occurred later, after SZ-Bu/Mel therapy (median 19 days v 7 days; P = .033), and four of eight cases were fatal (six of eight patients had underlying hepatitis infection), whereas three of three cases after FH-CEM therapy were moderately severe. Resource utilization associated with the number of days with fever, antibiotic use, and the number of transfusions administered was significantly higher after FH-CEM therapy than after SZ-Bu/Mel therapy.

Conclusion: Use of autologous stem-cell transplantation is feasible in the context of a resource-limited country.
