OBJECTIVE: To evaluate the effectiveness of a step-by-step protocol for GT-guided transthoracic biopsy in verification of peripheral lung tumors.
MATERIAL AND METHODS: A retrospective analysis of the results of GT-guided transthoracic biopsies of focal lung neoplasms was performed between October 2019 and December 2020. The analysis included the results of 176 biopsies in 158 patients.
RESULTS: Primary biopsy was informative in 139 (87.97%) out of 158 patients. There were 155 (88.07%) informative and 21 (11.93%) non-informative biopsies. Lung adenocarcinoma was diagnosed in 41 (25.95%) patients, squamous cell carcinoma in 35 (22.15%) patients, and small cell carcinoma in 9 (5.7%) patients. There were 17 (10.76%) patients with uninformative biopsy results. Sensitivity, specificity and accuracy were 86%, 95.5%, and 87.8%, respectively. PPV was 98.9%, NPV - 58.3%. Various complications occurred after 65 (36.93%) out of 176 biopsies (95% CI 30.15-44.27). Pneumothorax followed by pleural drainage was detected after 8 (4.55%) biopsies.
CONCLUSION: Accuracy of a step-by-step protocol for transthoracic biopsy was 88% that is not inferior to similar results in large-scale studies devoted to specialized navigation systems.
