BACKGROUND: Lung cancer screening with low-dose computed tomography has demonstrated at least a 20% decrease in lung cancer-specific mortality, but it has the potential harm of unnecessary invasive procedures performed because of false-positive results. This study reports the outcomes of a structured multidisciplinary lung cancer screening program in an area of endemic histoplasmosis.
METHODS: A retrospective review of patients undergoing lung cancer screening from December 2012 to March 2019 was conducted. Findings suggestive of lung cancer were presented to a multidisciplinary thoracic tumor board. Patients were assigned to interval imaging follow-up, additional diagnostic imaging, or referral for an invasive procedure. Invasive procedures were then compared between benign and malignant diseases.
RESULTS: A total of 4087 scans were performed on 2129 patients; 372 (9.1%) were suspicious and were presented to a multidisciplinary thoracic tumor board. Ultimately, 108 procedures were performed: 55 bronchoscopies, 7 percutaneous biopsies, and 46 operations. A total of 25 patients (1.2%) underwent bronchoscopy resulting in benign pathologic findings, significantly associated with an indication of an endobronchial lesion (P = .01). All percutaneous biopsy specimens revealed malignancy. Five patients (0.2%) who underwent resection had benign disease. Lung cancer was diagnosed in 67 patients (3.1% of the entire cohort), 46 of whom had stage I or II disease.
CONCLUSIONS: Lung cancer screening in a structured, multidisciplinary program successfully identifies patients with early-stage lung cancer with limited unnecessary surgical interventions. Patients with isolated endobronchial lesions should undergo short interval imaging follow-up to avoid bronchoscopy for benign disease. Future studies to minimize unnecessary procedures could incorporate biomarkers and advanced imaging analysis into risk assessment models.
