Conclusion
- Percutaneous transthoracic CT-guided lung biopsies are a useful, safe, and minimally invasive procedure in the diagnosis of lung lesions.
- There is a better success rate with FNA and core biopsies, but this may be related to a comparatively larger lesion size for this group.
- Whilst the rate of pneumothorax in this overall group of patients was relatively high compared to international literature; few required invasive treatment. Furthermore, the presence of any air in the pleural cavity was identified as a pneumothorax in this audit; it is unclear what criteria is used in international literature.
- Pneumothorax rates are higher for FNA only biopsies, but this may be due to smaller average lesion size increasing the difficulty of the biopsy.
- Ongoing use of FNA and core biopsies enable cytologic, molecular and histopathological analysis of lung pathology, contributing to advances in personalised cancer treatment.
