[Registries and clinical trials in geriatric oncology in Germany]

Regardless of the fact that elderly cancer patients in Germany are more and more recognized as a cohort with special characteristics and potentially specific needs, there is a lack of sound data from clinical trials that could guide the care of this population.

Finally, an overview of current clinical trials and registries in Germany is presented.
