AIM: To compare the success and complication rates of computed tomography (CT)-guided percutaneous core-needle biopsy (PCNB) based on the density of lung nodules, using propensity score matching (PSM).
MATERIALS AND METHODS: This single-centre retrospective study included 1,312 PCNB cases of lung lesions, including solid (n=1,120), part-solid (n=115), and non-solid nodules (n=77), that were detected between March 2013 and March 2021. The diagnostic accuracy and complication rates of pneumothorax and pulmonary haemorrhage were analysed before PSM. To perform PSM, part-solid and non-solid nodules were combined and newly defined as sub-solid nodules. The diagnostic accuracy and complication rates of pneumothorax and pulmonary haemorrhage were then compared between solid and sub-solid nodules after PSM.
RESULTS: Among the 1,312 included cases, the success rate and incidence of pneumothorax after CT-guided PCNB for solid, part-solid, and non-solid nodules were not statistically different (p=0.080 and 0.410). However, the rates of overall pulmonary haemorrhage showed statistical differences (p<0.001), particularly between solid and part-solid nodules (p<0.001) and between solid and non-solid nodules (p<0.001). After PSM, the incidence rates of overall pulmonary haemorrhage in solid and sub-solid nodules were 8.9% (17/192) and 29.7% (44/182), respectively, showing a statistically significant difference (p<0.001).
CONCLUSION: There is increased risk of haemorrhage in CT-guided needle biopsy of sub-solid nodules compared to solid nodules. Increased emphasis should be placed on the risk of pulmonary haemorrhage when consenting these patients.
