Genomic profiling of early-stage lung cancer for patterns of recurrence.

Abstract

e23126 Background: Currently there is no evidence to support molecular profiling for early stage resected lung cancer patients. However, up to 50% of patients experience recurrence following resection. This is a first-of-a-kind study utilizing comprehensive genomic profiling technology to characterize genomic patterns for risk of recurrence in early stage lung cancer patients within the community hospital setting who have undergone lung surgery. Methods: A total of 60 Stage I-II lung cancer patients, all having undergone pulmonary resection, were evaluated with molecular profiling of their primary lung cancer tissue using Foundation Medicine’s FoundationOneÒ test. Patient age in years ranged from 39-86, and all patients were confirmed Stage I or II based on final pathologic analysis. Samples were taken from three community hospitals that are part of the Addario Lung Cancer Foundation Centers of Excellence program. Patients whose tumors were resected between the years of 2009-2017 were included in this combined retrospective and prospective study. Results: More than 300 genes were evaluated using FoundationOneÒ and patients were segmented to establish similarities and differences. Analysis of segments include gender, recurrence, smoking status among others. Gene patterns across segments are beginning to reveal possible predictive profiles. Final analysis will be completed shortly. Conclusions: Genomic profiling could help predict lung cancer recurrence for early stage lung cancer patients. Similarities amongst patients with recurrences imply that early genomic profiling of lung cancer patients could help predict those patients who would benefit from adjuvant therapies including conventional chemotherapy. Genomic profiling for early stage lung cancer should be studied further and in greater detail to help predict those patients who would benefit from potentially early adjuvant therapies.
