complications were hemorrhage and pneumothorax. Hemorrhage rate in re-biopsy, male was 18.5% (10/54), and female was 3.4% (2/59). Re-biopsy needle size 17G (Angiotech 17G coaxial trocar together with Biopince 18G automatic biopsy needle) was 5.7% (5/87), and needle size 18G (18G Angiotech soft biopsy needle) was 26.9% (7/26). The mean frequency of intraoperative needle adjustment with and without hemorrhage was 3.3±1.8 vs 2.2±1.6. The mean distance (cm) of pleurato-target in with and without hemorrhage was 3.7±1.5 vs 2.3±1.9. High rate of pneumothorax for needle through interlobular septal puncture in re-biopsy, 62.5% (5/8). CT-guided percutaneous transthoracic needle re-biopsy of NSCLC was showed in Figure . Conclusion: First biopsy and re-biopsy complications were similar. Both of hemorrhage and pneumothorax were acceptable. CT-guided percutaneous transthoracic needle re-biopsy of NSCLC showed safe and feasible.
