Biopsy Frequency And Complications Among Lung Cancer Patients In The United States

Objective: This study aimed to describe the frequency and distribution of biopsy procedures for patients diagnosed and treated for primary lung cancer.Study design:Retrospective cohort study within an administrative database. Materials & methods: This observational study used data from the IBM MarketScan(R) Databases between 2013 and 2015. Results: The total number of lung biopsies performed among eligible subjects was 32,814; an average of 1.7 biopsies per patient. Bronchoscopy and percutaneous approaches accounted for 95% of all procedures. Complication rates by procedure are remarkably similar irrespective of biopsy frequency. Conclusion: Nearly half (46%) of patients in this population experienced multiple biopsies prior to diagnosis. Further, biopsy choice or sequence in patients receiving multiple procedures was unpredictable.
