Merging Genomics Public Datasets with Clinical Cancer Registry Data - Lessons Learned.

Publicly available datasets - for example via cBioPortal for Cancer Genomics - could be a valuable source for benchmarks and comparisons with local patient records. However, such an approach is only valid if patient cohorts are comparable to each other and if the documentation is complete and sufficient. In this paper, records from exocrine pancreatic cancer patients documented in a local cancer registry are compared with two public datasets to calculate overall survival.
