Background: Next-generation sequencing (NGS) of cancer gene panels is now standard-of-care for patients with advanced solid tumors. In July 2016, the Veterans Health Administration (VHA) launched the National Precision Oncology Program (NPOP) to increase access to NGS testing to VHA cancer patients across the country. A review of the prescription patterns among patients with highly actionable mutations is warranted to measure the impact of NPOP.

Purpose: The objective of this study is to assess the use of targeted therapies among patients with advanced solid tumors who received a Level 1, 2A, or R1 recommendation based on NGS results. For cases in which patients failed to receive targeted agents, underlying reasons will be identified. Study results will be used to improve outcomes of veterans undergoing NGS testing and the cost-benefit of NPOP.

Methods: This study will be conducted as a retrospective analysis of veterans who received oncologic care through the VHA and underwent NGS testing. From program inception in July 2016 until January 2019, the tumor samples of 5,897 patients have undergone NGS testing through NPOP. NGS results were categorized by Watson for Genomics (WfG), an artificial intelligence decision-support system. Among these, 608 (10.3%) samples noted to have at least one genetic variant with Level 1 or 2A actionability. The NPOP database will be queried to identify these patients who had a recommendation to receive a targeted agent. Prescribed and dispensed drugs will be identified from the Corporate Data Warehouse to indicate patients who have received targeted agents through VHA and compute the percentage of those who were not prescribed therapy through VHA. The medical records of patients who did not receive a corresponding targeted drug will be reviewed to identify non-VA drug use and code reasons if no record of drug administration is recorded. These codes will be examined for association with patients and tumor characteristics, sites of treating oncologists, and types of cancers. The most frequent coded reasons will be recorded, and assessment of this data will be performed to identify potential interventions to improve the utility of NGS testing for veterans.
