Immunotherapy in children: report from the Reisensburg-Symposium October 20-22, 2004 and recent advances.

Immunotherapy of childhood malignancies has a magic aura of promising an easy way to cure. It is not only the public, but also the medical community, which has caused this hope. Therefore, it was worthwhile to bring together a panel of experts working in the field of immunotherapy in order to discuss ongoing projects, and to show hopes and disappointments. The result was a fascinating symposium sponsored by The Kind Philipp Leukemia Foundation (Mönchengladbach, Germany). The symposium took place in the Reissensburg near Ulm (Germany) which gives the ideal location for such an event.
