Double high-dose chemotherapy and stem cell transplantation in adult Wilms’ tumor
2010
High-dose chemotherapy intensification and hematopoietic stem cell support remains a valuable treatment option for the rare patient with relapsed Wilms’ tumor. We report a 22-year-old adult male with an initially diagnosed stage II Wilms’ tumor, treated by nephrectomy followed by adjuvant chemotherapy. After 1 year, an intra-abdominal relapse was treated with salvage ifosfamide carboplatin etoposide chemotherapy followed by autologous hematopoietic stem cell mobilization. It was intended that he would receive two tandem cycles of high-dose chemotherapy; the first consisting of melphalan etoposide carboplatin; however, the patient did not return to receive the second cycle while in remission, but did return later with grossly relapsed disease. He was then treated with a novel preparative regimen incorporating high-dose topotecan (topotecan, melphalan and cyclophosphamide). This case confirms the feasibility of double high-dose chemotherapy with hematopoietic stem cell support in relapsed Wilms’ tumor. A de...
