Popis: BACKGROUND: Genomic signatures are revolutionizing the definition, identification, and treatment of breast cancer subtypes. The ability of genomic signatures to enable fine grained stratification of breast cancers to the granular disease level is still generally untested because of the difficulties in aggregating large clinical data sets. In order to stratify breast cancers into actionable subtypes both the full genome data and clinical data must be collected for patients at scale. DESIGN & METHODS: FLEX is designed as a novel, large-scale, population based, prospective registry. All patients with stage I-III breast cancer who receive MammaPrint (MP) or BluePrint (BP) testing on a primary breast tumor are eligible. FLEX utilizes an adaptive design which enables additional study arms at low incremental effort and cost by allowing targeted substudies to be added. Patients who are enrolled in the initial study will also be eligible for inclusion in any additional study arm where they meet all criteria. Additional study arms and substudies may be investigator-initiated. SPECIFIC AIMS: Primary: Create a big-data registry of full genome expression data and clinical data to investigate new gene associations with prognostic and/or predictive value. Secondary: Generate hypotheses for targeted subset analyses and trials based on full genome data. To date the following substudies have been proposed: DR. JENNIFER A.
