Selecting valuable patient cohorts for cancer biomarker discovery
Providing a scientist with prioritised datasets based on their scientific relevance to the research that the scientist wants to carry forward, allows for improved data selection, encourages data reuse and hence makes datasets more valuable.
Systematic and explicit data prioritisation is at the heart of Eagle's translational medicine platform. In a case study we show how the platform was used to select and prioritise the most valuable patients in the context of a specific customer project, namely the identification of genetic (haplotype) associations with skin cancer prognosis from publicly available information
We used the well-known patient dataset from the International Cancer Genome Consortium (ICGC), with over 20,000 patient donors. ICGC is unique in providing links to primary sequence data across many contributing projects. This provided our association analysis to include a greater number of samples than any single project such as The Cancer Genome Atlas (TCGA).
The stepwise process, from data modelling to usage and exploitation, enabled by our translational medicine platform is described in the following figure.
The systematic data organisation and valuation model provided by Eagle’s translational medicine platform allows for fast and effective patient selection for cohort building, followed by robust and reproducible correlation and association analysis.
We demonstrated the benefits of our prioritisation approach whereby we were able to select and prioritise the most relevant patients on explicit, well understood criteria and access their associated datasets in order to run complex comparison analysis between groups of patients to identify biomarkers, assist with stratification of patients and perform biological analysis of targets.
