Three-year Follow up of GMCSF/bi-shRNA(furin) DNA-transfected Autologous Tumor Immunotherapy (Vigil) in Metastatic Advanced Ewing's Sarcoma.

Ewing's sarcoma is a devastating rare pediatric cancer of the bone. Intense chemotherapy temporarily controls disease in most patients at presentation but has limited effect in patients with progressive or recurrent disease. We previously described preliminary results of a novel immunotherapy, FANG (Vigil) vaccine, in which 12 advanced stage Ewing's patients were safely treated and went on to achieve a predicted immune response (IFNγ ELISPOT).

Pilot Trial of FANG Immunotherapy in Ewing's Sarcoma.

We report on 12 consecutive patients with advanced/metastatic Ewing's sarcoma who were treated as a separate cohort of a phase 1 trial of FANG autologous immunotherapy (1 × 10(6)-2.5 × 10(7) cells/intradermal injection each month for minimum 4 months). Safety and clinical response were monitored.

Pre- and post-natal treatment of hemophagocytic lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a rare autosomal recessive disorder of infancy and childhood that is invariably fatal if not treated. We report on the first patient to receive post-natal HSCT for HLH after receiving in utero chemotherapy for disease stabilization.

Translocation (4;19)(q35;q13.1)-associated primitive round cell sarcoma: report of a case and review of the literature.

We report the 4th case of a primitive round cell sarcoma with the translocation (4;19)(q35;q13.1) as the primary cytogenetic abnormality. This undifferentiated sarcoma shows some features of Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET), including a diffuse reactivity for FLI1, but it shows only focal and weak reactivity for CD99 and is negative for a rearrangement of EWS, the molecular signature of ES/PNET.

Busulfan and cyclophosphamide as a conditioning regimen for pediatric acute lymphoblastic leukemia patients undergoing bone marrow transplantation.

Bone marrow transplantation (BMT) has become the standard therapy for children with relapsed acute lymphoblastic leukemia. The authors report their experience with histocompatible BMT for 52 children with acute lymphoblastic leukemia conditioned with a non-total body irradiation (TBI) regimen using busulfan and cyclophosphamide (Bu/Cy). The efficacy and long-term toxicity of the Bu/Cy regimen were determined.
