Trait: pancreatic ductal adenocarcinoma

Experimental Factor Ontology (EFO) Information
Identifier EFO_0002517
Description An infiltrating adenocarcinoma that arises from the epithelial cells of the pancreas. It affects males more often than females and the patients are usually over 50 years of age. Microscopically it is characterized by the presence of glandular (ductal) differentiation and desmoplastic stroma formation. Signs and symptoms include pain, loss of weight, and jaundice. It grows rapidly and is usually detected after it has metastasized to other anatomic sites. The prognosis is usually poor. [NCIT: C9120]

Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.
