Patient identification and data elements

Patients included in this study had commercial health plan coverage from Anthem at the time of their HIRE-Oncology record of interest and could be linked to HealthCore’s administrative claims database. HIRE-Oncology data from June 23, 2014 through June 1, 2015 for patients with breast, lung, or colorectal cancer were used for this study. The data elements obtained for this study included cancer type, cancer stage (0, I, II, III, IV, or limited), biomarkers unique to each cancer type (breast: estrogen receptor [ER], progesterone receptor [PR], and human epidermal growth factor receptor 2 [HER2]; lung: epidermal growth factor receptor [EGFR] mutation, anaplastic lymphoma kinase [ALK] mutation; colorectal: KRAS gene mutation), and the histology of lung cancer (small cell vs non-small cell). Additionally, age and gender were captured from the HIRE-Oncology data.
