Abstract

Objective: To determine the necessity of percutaneous lung biopsy in patients with a single known primary malignancy and multiple pulmonary nodules. Design: Retrospective study. Setting: Tertiary care university hospital. Results: We reviewed all percutaneous lung biopsy specimens over a 6-year period. One hundred forty-six patients with a single known primary malignancy and multiple pulmonary nodules had biopsies performed up to 19 years following diagnosis of the primary neoplasm. One hundred thirty-seven biopsy specimens (93.8%) were positive for metastases. Eight patients (5.5%) had a nondiagnostic biopsy specimen; however, subsequent imaging studies and the clinical course strongly suggested diffuse metastatic disease. One patient (<1%) with breast carcinoma developed nodules 3 years after initial diagnosis and had resolution without a definitive diagnosis or therapy. Conclusion: Patients with a single known primary malignancy and multiple pulmonary nodules who present for percutaneous needle biopsy will have pulmonary metastases in the vast majority of cases. Biopsy in these patients rarely changes the clinical course as other diagnoses are rarely established.
