The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.

Overcoming Barriers to International Clinical Trials for Rare Cancers
Friday, December 10, 2010
Location:
Bethesda,
Maryland
Description: The goals of this conference were to introduce key institutional players to the topic of international clinical trials in rare cancers and to establish an ongoing dialogue. Participants left the meeting with a set of specific priorities that need to be enacted to promote these trials. The meeting promoted consensus on the way that resources are prioritized to address rare cancers. Participants were asked to convey the content of the meeting to their constituencies and to follow up with pilot concepts.
