OBJECTIVES: The purpose of this study was to evaluate the complications and diagnostic accuracy of computed tomography-guided percutaneous transthoracic needle biopsy (PTNB) in patients aged 80 years and older. MATERIALS AND METHODS: Consecutive PTNB procedures performed in an academic institution between July 2009 and June 2013 were reviewed. Procedures were performed according to a standard protocol using conscious sedation and rapid on-site pathology evaluation. Patient demographics, lesion characteristics, complications, and final tissue diagnosis were reviewed. Patients below 80 years of age and over 80 years were compared using binary logistic regression. RESULTS: Of 894 biopsies, 141 (16%) were performed on patients over 80 years of age. Comparison of patients over and below 80 years of age did not differ significantly with regard to lesion size and morphology (P=0.663 and 0.453, respectively), and diagnostic accuracy (P=0.268). Pneumothorax rates were 23% versus 24% (P=0.682), and chest tube insertion was required in 2% of both groups (P=0.924). Hemoptysis rates were 3% versus 2% (P=0.376). CONCLUSIONS: PTNB is a safe and accurate procedure in patients aged 80 years and older. Complications and diagnostic accuracy are similar to those observed in younger patients.
