Long-term graft-versus-tumor effect following reduced intensity hematopoietic stem cell transplantation in a child with metastatic renal cell carcinoma.

Pediatric renal cell carcinoma (RCC) is rare and different from adult RCC. Although target agents have recently been introduced, allogeneic hematopoietic stem cell transplantation exploiting graft-versus-tumor effect still remains an important treatment option for metastatic RCC. A 2-year-old male with RCC developed hepatic metastases 6 months following radical nephrectomy and subsequent cytokine therapy.

Selective embolization of the internal iliac arteries for the treatment of intractable hemorrhage in children with malignancies.

Purpose: Acute internal hemorrhage is an occasionally life-threatening complication in pediatric cancer patients. Many therapeutic approaches have been used to control bleeding with various degrees of success. In this study, we evaluated the efficacy of selective internal iliac artery embolization for controlling acute intractable bleeding in children with malignancies.
